two days to perihelion?

I heard it dropped in magnitude yesterday.

>>6185504
Last observed mag. was 3.8.

>>6185500
I'm so hard for this.

It's expected to stay on the FOV for two days, so it's going to plunge fast!

updated

>>6185587
That's like an hour difference right?

It's amazing how fast that little bugger is going.

so will we be able to see it in daylight?

>ITS HABBENING.jpg

>>6185604
I second this fags question. What is minimum magnitude to see in the daylight? Ive seen Venus in the daytime but Venus isnt RIGHT NEXT TO THE FOCKIN SUN

>>6185604
Not yet. It's too close to the sun, it gets blotted out in its glare.

>>6185613
I'd also like to say that you should be able to see it starting around the 3rd of December.

Im not seeing OPs image but the ive been watching it creep across the HI1 cam for a few days now.

>>6185500

did he died?

He comes.

The Sun greets the new visitor
(standard CME concidence)

Damn, that little guy is really booking it!

>>6186124
Hit the accelerator!

>>6186167
What if the sun was sentient and it's throwing out solar ejections in order to swat down the fly that's buzzing around it's head. Like some sort of perimeter defense.

>>6186274
>What if "hur Durrell dur har de der"

Stop.

>>6186274

This type of electrical interaction is quite common it but has no place in standard science and is always called a coincidence, no matter how often it is observed.

Repeat after me (Axioms of astronomy):
Space is electrically neutral.
Gravitation is all there is.
Comets are dirty little snowballs.
The Ancients were all idiots,
better ignore their records.
Or else..

In a year from now we will probably know better.

There is a recurring theme across many civilizations where they were watching the skies: They knew something like a "dragon" would come and destroy everything as it had done already many times before.

"The earliest recorded myths are those of combat, between a god or hero and a dragon. The dragon was a familiar figure in Greece, Egypt, Mesopotamia, Babylon, India, China, North America and elsewhere. Usually, he has the form of a winged serpent. He is a gigantic monster; he spouts fire and smoke; bellows and hisses; he throws rocks, and is the creator or terrible destruction; and his home is in the sky." - Victor Clube, Bill Napier "The Cosmic Serpent"

>>6186318
>The Ancients were all idiots

No they weren't, but you sure are.

>>6186318
the reason "fireball events" continue to rise is better detection technology.

>>6186318
There is on average one CME per day so yes CMEs and comets is quite common but that isn't strange.

Space is mostly quasineutral, learn some plasma physics.

>>6186261
I see two tails !!

>one CME per day

next one brewing?

By the way, on http://cometison.gsfc.nasa.gov/# the perihelion fly-by will be live.

>>6186701
One is the ion tail and the other is a dust tail :)

HYPEHYPEHYEPHEYPE

I was outside yesterday freezing my arse off standing behind a garage blocking the sun trying to see this piece of shit 5 degrees away from the sun.

Obviously no luck.

HOLY SHIT ISON IS ACTUALLY AN ALIEN AIRPLANE
CAN'T YOU SEE THE WINGS

Antares (lower left) also has 'wings'.
Sensor saturation effect.

will it survive?

>>6188255

doubt it

>>6185500
How did you get picrure, looks like nasa shut it down for iphone users. I've been getting nothing for a day and a half

>>6188259
It works on android.

>>6188255
I can see that comet coming out in lots if pieces as it goes on the turn around and a few strike earth. Awesome shit

>>6188259
That app isn't maintained by NASA nor ESA, it isn't official.

The best site by far is:

>>6188264
Not the person whom your quoting, but on my nexus 5 i don't see on the page... sooooo....

sohowww.nascom.nasa.gov
is currently super slow, use the ESA mirror
soho.esac.esa.int/data/realtime-images.html
but the latest C3 image is still 9:18 UTC

>>6188282
Three hours old? Today? Nice job, SOHO.

Finally, a new image.

>>6188361
Oh man, it's so close.

>>6188365
About 5 hours to perihelion. Kind of exciting.

>>6188361

>>6188374
He of the two tails!

Here's a countdown clock thingie (technical term):

http://www.cometison2013.co.uk/perihelion-and-distance/

That's how it looks from space now. Space Engine.

>>6188380
And that's how it will look on perihelion from surface of the Sun.

Eek!

Actual speed of comet

perihelion soon

Going, going...

Not sure how long we'll have to wait after it passes behind the coronal disk to see if anything comes out the other side. 3-4 hours, maybe? Anyone?

Godspeed little doodle!

>>6188548
Man, SDO satellite will make photos of the comet behind the disk.

http://cometison.gsfc.nasa.gov/#

Starts in 1 hour and 15 minutes.

>>6188548
How are you getting this images so soon before nasa gets them? Tell me the website

>>6188553
Thanks very much. Will be watching.

All images I am getting are from:

Why do the feeds flicker?

>>6188633
Site is down.

>>6188696
NASA pls

Should I grab normal binoculars (don't have anything else) or do you think It's visible without.

>>6188633

This is all I'm getting from the links.

>>6188701
>Visible
>Now

is there a mirror for the streams? i can't get any of these to work

>>6188706

>>6188711
In 2-4 days. Now it's too close to Sun.

That sucks. ;/ I was actually getting into astronomy.

I always wanted to ask. What are those little particles that fly near sun? There are alot of them.

>>6188747
Stars

>>6188751
but stars are motionless and there are some particles that fly with high speed.

>>6188718
>"SOHO IMAGES ARE LOOKING LIKE COMET HAS BROKE UP"


FUG

>>6188753

>stars are motionless

When did this happen?

>>6188762
bugger got vaporized

>>6188766
please answer my question

comet debries?

>particles that fly with high speed.

CCD sensor cannot be shielded from proton impact. Now and then they do a 'bakeout' to counter the degrading effect.

>>6188774
source?

>>6188771

I don't know what those particles are. They could simply be space debris burning up as they approach the sun or they could be ejections of some kind from the sun. They could be neither of these things.

But stars are not motionless. Stars orbit the centre of their parent galaxy and galaxies themselves also move through space with one-another.

Dammit...

I haven't seen a great Comet since Hyakutake in 96. I really thought this one was gonna make it.

>>6188863
I haven't seen a comet ever

>>6188873

>>6188873
We will, one day.

how long until we know for sure it's gone?

>>6188879
not long. It should've reached perihelion 25 minutes ago

>>6188873

You haven't seen Hale Bopp?

wow you really must be 12.

Hold on guys let's not get excited here. I just woke up, soho webiste is slow I decide to check sci. RIP ISON RIP ISON FEELS NEVER SEEN A COMET.

You guys nearly ruined my thanksgiving. Even if it breaks apart it still should be visible. R r right?

they said on the nasa stream that they shouldve seen the comet by now

no comet for u

>>6188906
Us northern hemisphere dudes keep getting fucked. No mcnaught, no lovejoy. I did catch panstarrs last spring. Wooo.

>>6188907
yeah we should be able to see debris... nothing yet? weird

>>6188906
Ah Hale Bopp. I remember it like it was yesterday... still one of my fondest childhood memories

>>6188917
Hale Bopp was northern hemisphere, I saw it from the UK

>apollo 13, houston, do you read?

Maybe its taking longer to emerge because of the lack of moonrocks on board?

>>6188920
Same. And that fucker was visible for quite a long time. 18 months according to wiki

>>6188932
Wasnt visible in Poland. As far i know, last comet visible here was in 1881.

>>6188917
Yeah, I know. Last one I've really "seen" up here. I remember a year or two before hale-bopp there was another comet, forgot the name.

I was like 7.

>>6188921

I saw Hale Bopp in San Diego, in the sky over the morgue where the Heaven's Gate dead people were.

>>6188906
I guess Australians are largely ignorant of such things, I was six at the time and never heard about it from anyone.

>>6188906
I remember staying out for Hale Bopp, but I don't remember the comet, just Cassiopeia constellation

The sun blew up

>>6188942
Someone knocking on SDO while trying to take a pic. Rude.

>>6188937

>>6188942
8 minutes and 19 seconds of sunlight left

>>6188942
I was watching lovejoy perihelion from 2011 last night. On these corona images the comet basically disappears. I'm assuming because they're in UV light. The tail didn't refore until it was like a few solar radii away. Ill see if I can't find video and link to them.

>>618895
This doesn't show the closeup but you get the idea.
http://m.youtube.com/watch?v=XjAS8fOoblo&desktop_uri=%2Fwatch%3Fv%3DXjAS8fOoblo

>>6188938
so, did you get to see this comet, in '07?

>>6188952
Oh yeah I saw that. The comet 'disappeared' in the corona because of the heat. lovejoy disintegrated

>>6188960
No I was only in Australia until 2003

>>6188965
ah damn. You missed out, I wish I could've seen it :(

also, ISON??

>>6188980
nope

http://www.youtube.com/watch?v=D-FCk9CgCRY

It's clearly visible that comet disintegrated.

>>6188988
damn. ISON is kil :(

Please, just let it be that the tail disintegrated...

GIVE ME MY COMET

Anyone else saw it?

Comet ISOFF

wow. Youtube never ceases to amaze me

>>6189001
Hmm...doesn't look like a comet but...

from an hour ago

>>6189001
source?

>>6189023
Alive? Dead? Dying?

If Ison survives will he trump Bopp as the brightest and best visible comet ever?

>>6189024
http://cometison.gsfc.nasa.gov/index/kiosk/dataset/one_0211

>>6189035
Evaporated

>>6189036
If it did survive (pretty much a given it didn't) No, it wouldn't have been as impressive as Hale Bopp was/is.

I think ISON was about.. 10 times smaller than Bopp was or something

>>6189003

>>6188906
Hale Bopp stands out as one of my favorite chapters of my life. I was 18, 19. Partying all night and tripping out stargazing and not really realizing how significant an event it was at the time

gif

>>6189038
>17:49
this is pretty interesting, even shows up on the other cameras

>>6189077
Pretty much sums it up.

>>6189077
yeah, it's a goner :/

But, because of ISON's break-up, proves that one guy's theory of how planets were formed

>>6189001
That's an artifact from a cosmic particle.

Comet in motion. Wahhhh it never made it out

>>6189077
I'm sad that this happened, but on the other side it's amazed that we can watch it happen and have a gif of it. Also I love you /sci/, there's no other source where I can find cool stuff like this so fast.

>>6189069
I remember it as well. I too didn't realize how significant it was, but I was still very impressed at being able to see it, even in the super-bright heart of Paris. My classmates didn't seem to give a shit.

I was just turning 5 when Hale-Bopp passed by Earth. I looked it up and the next time it will come around is circa 4,300 AD. This makes me feel very unimportant. :/

What would happen to the material delivered to the Sun by Comet ISON? Would it give more 'fuel' so to speak, for further nuclear fussion? Or is this amount so negligible that wouldn't improve our suns life span?

Quote:

"..the Sun fuses 620 million metric tons of hydrogen each second."

>620 mln metric tons/sec -> hydrogen

^WTF??? That seems like a ridiculous amount!!!! Any clarifications on this??? ty

>>6189161
it'll evaporate before it hits the sun, whatever minerals/ice it's made of

>>6189161

multiple exclamation marks.

a sure sign of a diseased mind.

>>6189161

Are you 12

I don't think you should be here

>>6189161
To radiation alone the Sun looses about 4 million tonnes a second. The comet material likely wont hit the Sun, it'll either be carried away or continue orbiting.
The Sun doesn't burn all of it's hydrogen, only what's in the core and even then only a certain fraction. Even if the comet hit the surface it's hydrogen would not be burnt.

>>6189171
>>6189174
I don't understand? Simply adding more exclamations to show a certain importance for some desired knowledge is diseased? You're all on 4chan so fuck off with this.

>>6189165
if it'll evaporate i'm sure the gas will be dragged in by the sun's enormous gravitational field.

p.s. still mind boggled at the 620mln metric tons/sec of fussion

>>6189193
wow, thank you for that, can't believe there are people like:

>>6189171
>>6189174

on /sci/.

>tfw we will discover another comet of century in next 10-20 years

From the latest image it appears something has actually come out the other side. Looks like a shell of its former self though and will certainly not be visible from earth.

>>6189203

I can't believe there are people as stupid and clueless as you on /sci/.

>>6189262

>>6189262
...where?

>>6189262
Please let it be

>>6189269
the faint streak near the top left

>>6189257

>>6189269

IT's very faint. Just follow the arc of the comet from the upper left corner of the pic. You can see it poking it's head out from behind the sun (bottom right of the sphere). Not the comet of the century, but it appears to have avoided being totally evaporated.

>>6189262
Someone check the blue soho camera. If it survived, it will be there.

>>6189278
would you say its 'turtling' or 'tipping' ?

>>6189287
ded

Debris following what should've been ISON's path?

Why do you think it's dead? To me it looks like it's at the other side of the sun right now.

>>6189262
plait said this is tiny debris following the path of ison but SDO would see it if it were still a comet

the happening is still happening!

>>6189262
that actually looks like a pretty bright head

maybe some nucleus survived?

Nothing showing on the latest SOHO.

>>6189327
I can't get on the SOHO site

but, if it's not on SOHO, it's probably just debris

Everyone relax. ISON just went back to 1986 for a bit to find some humpback whales. it's now on its way to save Earth.

Sun op.

>>6189327
Not far enough yet. Soon though.

My guess is there was a tail separation event just as the nucleus approached perihelion.

>>6189237
what does it say?

>>6189327
It wouldn't show up on the C3 images just yet. The red C2 images are a bit closer and C3 blocks a larger area. Prolly another hour before C3 can display anything.

>>6189327
i like the comet at 10o'clock

>>6189320
>>6189320
>>6189320

>>6189340
This gives a bit of perspective of the C2 and C3 views. This is from just before the final plunge.

>>6189343
I dont see anything

>>6189361
to the left of the sun

ISON is dead, long live ISON!

Latest SOHO LASCO C2 image

>>6189374
maybe I'm hoping too much here but, is it brightening as it goes? It's probably just a corpse now but... just maybe it survived?

>>6189380
>>6189320

>>6189380
i dont see a nucleus but that looks like something

>>6188820

There is that too and, as others have been saying it it probably protons.

>>6189382
oops, thought that was the prior one.

>>6189380

It just updated again.

Looks hopeful but im no expert

>>6189381
Compare the recent images to the pre-perihelion ones. ISON is kill.

I-i-it's moving!

I-i-it's Alive?

IT'S ALIVE

>>6189390
...
As God as my witness I thought that thing was gone.

I don't care if that thing is a shell of its former self.

Something made it out.

>>6189390
Its just torn-up debris. Compare it with >>6188623

http://www.bbc.co.uk/news/science-environment-25143861

>>6189398
Well it is brightening so hard to say yet. If the comet had partially fragmented, then the Sun's gravity may have cleared its dust cloud. It is now starting to reconstitute. It will take some time for that to happen IF this is the case.

muh NASA conspiracy

TOP LEL

Ison is just running for her bigger, undiscovered brother, to show the sun they didnt ended yet!

>>6189403

>>6189429
Every 15 minutes or so on the C2, 30 minutes on the C3 I think. Times are a bit off with all the server load though.

Nothing yet on the latest C3 but that's expected at this point.

>>6189430

Holy shit how is this even possible? Is there any reasonable explanation for this?

>>6189430

now do one where it's heading straight to the camera, and make it a .gif

(In reality, this thing's solar food. Yum! How many millions of tons of hydrogen were in it?)

>>6189445
it's a shop my friend

>>6189445
I never thought I would see it - supporting evidence of the photoshop effect. This is a massive leap forward in science.

>>6189454

Shit, it's definitely brightening as it comes out of the solar disk, and fairly quickly. It will probably not reach it's former brightness, but still. It's not dead.

>>6189454
why does the sun fart on the opposite side whenever a comet passes by/plunges into it?

Guys, in this at the top left is a dot that moves slowly to the right.

Is that anything specific or some random object in the background?

Does the fact that it's brightening rule out the possibility of it just being a remnant of the tail?

>>6189475
Mercury.

>>6189477
In my entirely unofficial opinion as a space nerd, most likely.

Chances of it being easily visible later, no clue

I want off this ride. I fucking knew that no matter what happened the crazies would jump on it and make bold conclusions. God damn.

I don't know yet... the area where the nucleus should be isn't bright enough imo

I'd love it to have survived but... i dunno

Well you got that right. They believe it all purely because it's fun and sensationalist, but the masses of disinformation is disheartening. Just more people who go to prove they know and want nothing to do with space sciences because it's all evil/cover ups/aliens.

I want a Rendezvous with Rama scenario more than anyone, but damn people are grasping at straws way too fucking hard.

Dust in the wind
all we are is dust in the wind

>>6189518
It clearly surived.

>>6189522
we'll have to wait and see to be sure

>>6189522

That's just loose dust. You're seeing what's left. The nucleus broke apart. A lot of it got gobbled up for Thanksgiving.

Thread's anthem:

That thing is just 1km in diameter. If it got destroyed, I don't think the streak would go on like that. If it was debris, it would have dispersed much more.

So there's no chance now of the whole "see it with the naked eye, huge as fuck" anymore?

>>6189539

:^)

>>6189532
it fragmented, so it would follow a similar path. Jut look at what happened to Shoemaker-levy 9, it disintegrated before hitting Jupiter

Why is the sun always blocked out in such images?

latest image

>>6189553

>>6189553

It has to be so it doesn't block out the rest of the image.
Too bright to look at.

>>6189553

Because pointing all but the most specialized cameras at the Sun is a bad idea. A camera that is meant to see the corona and incoming comets isn't going to do well pointed directly at the Sun.

>>6189554
forgot pic

>>6189543
those explosions were larger than the earth. so scary. ;_; i was getting ready to poo when nasa said that a comet was going to hit mars in 2014. that is too many massive impacts in too short a span of time for it to be uncommon. i think they decided that one is going to miss tho.

>>6189543
that was more of a fragmentation by Jupiter's gravity. the sun actually melted ISON

I want a comet to hit us or the moon.

pls no. i liek being among teh living. i am too soft and useless for a lucifers hammer type apocalypse.

>>6189496

Anybody?

>>6189580
yeah - i think it has something to do with how hubble works. it is common and many tinfoil hats ran with it.

21:48

Did it actually go through the Sun's corona? Shit's way too hot as far as I know.

>>6189580
>>6189496

Yep.

>>6189589

ITS ALIVE

>>6189588

>it is common and many tinfoil hats ran with it.

Hence why it's on the front of /x/ right now. God forbid you try to tell them what it really is though.

>>6189588
yeah and ison was way too small. they first said it was 3 miles wide. now they are saying it was only half a mile. and that is just too small for how close it got.

>>6189589

Meh, it's done.

>>6189596
the internets scares me. when i was watching a nasa hangout on youtube today the comments were embarrassing and insulting to the smartfags who were talking. i bet eventually all comments everywhere will get turned off - you know - except on 4chan.

>>6189569
Oh of course - very different circumstances, but the sun melted the ice in amongst the rock parts, so it probably fragmented much the same way.

Still, there was no force to actually push the pieces apart; the debris would still carry on in the direction ISON was heading due to it's momentum... I guess. I dunno, I'm drunk

>>6189591
yes. what we're seeing here is dust

>>6189617
i think you are right but i heard a nasa guy say that he thought the actual rock fragments were vaporized when it went through a cme. but i bet he doesnt know for sure

>>6189622
How did anything of it even survive millions of degrees?

>>6189627

>millions of degrees

lel try like 6,000

>>6189627
bits of rock mostly

Looking at this, it's clear to see it vaporized before it even reached perihelion

http://www.youtube.com/watch?v=6j6nkLnHyG0

>>6189627

Only about 2500. It didn't enter the corona.

>>6189615

Yeah agreed, I watch the NASA hangouts too well as all their content and it's seriously cringe-inducing to watch the /x/nauts spew their conspiracy shit.

I get why people become all agitated by stuff like comets, but some of it is borderline insulting. And I despise the morons like BPEarthWatch and ThorNews on Youtube who get hundreds of Likes in hours of their brain dead conspiracy uploads yet NASA channels remain relatively barren.

But eh what can ya do.

>>6189627

The surface of the sun is only like 10,000 murrican degrees

the core is like 18mil

>>6189652
We are talking about the corona which can heat up to some millions of degrees.

>>6189642
the surface of the sun is 5800k where as the corona is one to three million kelvin

millions of degrees

The term "degrees" really doesn't translate well when discussing magnetic plasma. Yes, parts of it can be that hot, but only when ___ and only in ___ and it's not really "heat" because ___ (seriously, you'd need to take a college course on this stuff).

Basically, what happened was that the comet was blown to pieces on its way in, and a diffuse cloud of plasma slowed down considerably when being flung through another diffuse cloud of plasma.

“A star just fell from the sky.”

“That is not an ordinary star, my son. That star is the tear of a warrior.”

“What warrior is it?”

“A lost soul who has finished his battles somewhere on this planet. A pitiful soul who could not find his way to the lofty realm where the great spirit awaits us all.”

>>6189665
>but only when ___ and only in ___ and it's not really "heat" because ___
What does that even mean? Why is degrees not good to describe heat? The corona is fucking hot, so what's the deal?

>>6189665
There is nothing wrong with degrees. You can argue that temperature isn't applicable because it isn't in equilibrium but you can define a temperature, so degrees is just fine.

>>6189674

>>6189681
So is empty space, yet it's also cold as fuck.

>>6189674
;___;7

I've been meaning to watch this

>>6189690
do it

>>6189686
i was hoping that was the song you posted. great song for sky watching.

>>6189681
I don't think he knows what he's talking about. Heat in physics is the flow of thermal energy, you shouldn't use it in that context. The corona is very hot indeed, but it is very diffuse.

>>6189688
What exactly are you trying to say.

>>6189688
Space is neither cold nor hot, actually.

22:24

>>6189712
is that supposed to happen?

>>6189708
It's both depending on the definition you use.

/pol/ here

What would happen if you were to go out into space without a protective suit? All UV rays and radiation shit aside

Would your body just prune up into a midget?

>>6189724
You'd freeze or burn to death.

>>6189730
is this just a theory, or has it happened before

>>6189736
both

>>6189739
3 russian dudes died in space ue to hypoxia
why are you such a lying cunt?

>>6189712
I'm 80% sure it's dust now but... looking at this picture... I honestly don't know. I'm still holding out for it to survive in my heart but I know in my head ISON died...

fuck I don't know, it's certainly dimmed but... the tails are back?

ded

22:54

ISON coming back in SOHO's view

It's now with C3's range of view. Looks quite a bit brighter from this camera.

If comets melt so easily in the viccinity of the Sun, then why don't we just deploy all of our atomic waste there. Problem solved?

>>6189786

I was under the impression that spending it there and wasting massive amounts of fuel wasn't worth it.

>>6189724

You wouldn't die until you drown from lack of oxygen. So you'll live a few minutes.

The deadliness of space is vastly, extremely overexaggerated in most media.

>>6189786
Because if something goes horribly wrong, then we dun goofed hard.

>>6189786
Because of the absurd amount of fuel it would take to make something that heavy venture out of the limits of our atmosphere into space, I guess.

>>6189780
I'm not into space stuff... but what's that circle inside the sun?

>>6189724
You can stay in space for up to 90 seconds and still be rescued but you lose consciousness in about 10 seconds.

>>6189811
Mercury's orbit.

>>6189811

It's the event horizon of the mini black hole in the middle of the sun.

>>6189811
The Sun's poophole.

just made this gif

what is this, right now? ISON, you got some 'splain' to do

I feel like an abused wife, I'll never leave you ISON honey, I love you no mater how hard you beat me

>>6189858
Looks like the tail had the crap beat out of it

LIVE
LIVEEEEEEEEE

>>6189865
ah crap I've had too much to drink, sorry for the typos

23:24

>>6189858
I think it got fucked when it hit the plume at 5 o' clock

23:24.

>>6189634
Kelvin or Celsius

>>6189014
That's not exactly a case of youtube retardedness.
That's just your average person right there.

>>6189896
This can't be just debris.

>>6189896
and from C3

>>6189906
It's just a shadow of its former self, though.

Plasma Discharge Comet Model: 1
Dirty Snowball Comet Model: 0

>>6189908
little SOB made it through.

get up early

>>6189929
We probably won't see shit given what's left of it.

23.48

Ison is out of C2 FOV, switching to C3.

>>6188906
Other person, I was 6 when Hale Bopp was around. Don't remember though.

>>6189865
But, from what I remember about comets, isn't it supposed to come out tail first? This is interesting. I think we're all going to die.

>>6189945
Where did you get the 23:48 image? On the SOHO website the latest is still 23:24

>>6190000
It comes out tail first when there's still a nucleus to make a tail from. This is just debris and shit.

Nice quads btw

>>6190002
refresh the page nigger

>>6190007
Thanks.

Like the flames shooting out of WTC #1 after the second plane hit it. This was all over when I fell asleep three hours ago. I find it very disturbing in an "am I really awake?" sort of way.

STEREO B is back

>>6190031
Not too shabby for a "dead" comet

looks like it's still going to be pretty damn bright come mid december

>>6189615
>>6189649

Jesus fucking Christ, despite the NASA videos clearly saying THEY'RE NOT 100% CERTAIN whether it survived the trip or not, all the morons are jumping out spewing bullshit going HAHA NASA WRONG AGAIN, CAN'T YOU GET ANYTHING RIGHT SHILLS HURRDURR.

I just can't wait for this to be over so they can go back into their caves and claim it's all covered up or some shit.

Another gif from LASCO C2

>>6190046
I for one am thankful for this holiday shitfest. Most fun I've had on /sci/ in a while

nasa lied
sci cried

>>6190046
I've had my biggest moments of rage and cringe when reading the comments on Curiosity's feed after it landed, when media attention was at its maximum it attracted hordes of massive retards.

Chris Hadfield's feed also had a fair amount of idiots. But the worst is IFLS's comments, a constant stream of stupid.

>>6190054
its still pretty bright. we should see it tonight, right?

>were still going to pass through the coma and get plague

>>6190046
Of course NASA isn't certain, their the real scientists.

WE on the other hand are professionals at mashing F5 and talking out our ass about the pixels

we're all gonna die

>>6190069

Reminder that this slack-jawed moron has hundreds of Likes and far more views than any sensible/NASA videos in less than 24 hours.

http://www.youtube.com/user/BPEarthWatch?feature=watch

He's spent the past 12 months making hundreds of ISON/Nibiru videos, so he's gonna have to pull some real good shit out of his arse once nothing special happens.

I'm willing to bet ISON will be "Just a sign of the Lord" and other bullshit. I don't mean to get mad over this stuff, but it's so damn disheartening to have people jump on the sensationalist Biblical bandwagon.

A little tidbit from a guy from the Naval Research Lab that helps run LASCO...

Sungrazer Comets @SungrazerComets 29m
Matthew Knight and I have looked at literally a couple of thousand sungrazing comets. We've NEVER seen one behave like #ISON. Astounding!

>>6190054
When we gunna know how much of it survived? Something is there but goddamn it looks pathetic.

>>6190060
GTFO assbitch

>>6190081
That's pretty cool. Shows there's always something new to learn about out there.

>>6190078
Jeez, I wish I was on ISON right now.

who else thinks it might have pulled a shoemaker and fragmented into multiple pieces?

>>6190145
Probably. Also, correct me if I'm wrong, but if it was still in one piece, wouldn't there be a clearly defined tail directed AWAY from the sun by now?

>>6190145
at this point seeing what this little fucker has done this far, I don't believe in anything.

>>6190078
Looks like we've got a winner here.

>>6190161
Ah, science. Always fucking everyone with your "evidence." This is so much better than being anything anyone expected.

https://www.youtube.com/watch?v=RV7Qz640OeM

Sungrazer Comets @SungrazerComets 2m
Alright we're calling it, and you heard it here first: We believe some small part of #ISON's nucleus has SURVIVED perihelion.

>>6190183
You clearly don't understand what science and evidence are.

I wonder what we'll see when SOHO is back up (it drops out for a short period each day hence no updates for the last few hours image wise)

Although it survived, I don't think it's on track to be much of a spectacle... I'd love to be wrong, though.

What's with all these religious conspiratorial drivel in this thread? Fuck off and do so fast.

its a shame its cloudy all over the east coast. i want to SEE

>>6190269

If you're looking for more rage, head on over to /x/.

best chance for naked eye visibility is after Dec 6 according to this

The tail is swinging around. Check them latest .gifs.

update. bitch is go.

>>6190520
I would hazard a guess here and say it's getting slightly brighter


Brilliant news to wake up to :)

BBC

>Comet Ison, or some part of it, may have survived its encounter with the Sun, say scientists.

The giant ball of ice and dust was initially declared dead when it failed to re-emerge from behind the star with the expected brightness.

All that could be seen was a dull smudge in space telescope images - its nucleus and tail assumed destroyed.

But recent pictures have indicated a brightening of what may be a small fragment of the comet.

Astronomers admit to being surprised and delighted, but now caution that anything could happen in the coming hours and days.

This remnant of Ison could continue to brighten, or it could simply fizzle out altogether.

"We've been following this comet for a year now and all the way it has been surprising us and confusing us," said astrophysicist Karl Battams, who operates the US space agency-funded Sungrazing Comets Project.

"It's just typical that right at the end, when we said, 'yes, it has faded out, it's died, we've lost it in the Sun', that a couple of hours later it should pop right back up again," he told BBC News.

The European Space Agency (Esa), too, which had been among the first organisations to call the death of Ison, has had to re-assess the situation. A small part of the nucleus may be intact, its experts say.

Excellent work tonight, gentlemen.

/sci/

When will this be visable in Euroland, and do we know how much has survied yet? I've got the opertunity to use our holiday house to go see this, it's in the north of scotland with almost no light pollution.

I've never seen a comet before so I think it'll be pretty interesting

Battered comet, anyone?

http://www.youtube.com/watch?v=g-xElDCtgS0
it look like there is something left of the core, i could make a crappy gif but i'm sure someone will make one.
>>6190729
see
>>6189929, as whatever is left of ison moves away from the sun it will rise in the east earlier and earlier each day. binoculars may be helpful.

>>6190673
It looks to be following this simulation pretty closely, including the tail twisting around:
