VY Canis Majoris- Largest star known to man

try this one

This is the kind of shit that really ruins a five year olds' perception of reality.

I was doomed as soon as I first looked up at night.

>>2546111
That's fun and all, but there is no analog to nerve impulses in the universe at that scale.

>>2546150
Fractal reality, negro.

I guess this is cool. In 4.5 billion years this bad boy is going to collide with our own galaxy.

If you didn't read any science fiction, get the fuck out of /sci/ and go back to your imaginary college buddies.

The Universe, in a sentence: Hydrogen is a light, odorless gas, which, if given enough time, becomes everything.

starfox?

im sorrry starfox but i cant let you do that

>>2546111
Fucking saved!

>>2546155
Dude... buzzkill, Also my face melted. Hopefully my hovering thetan will survive this merger.

Here's an extremely simplified version of how you get to the moon.

>>2546200

The small blue dot in the very top of Buzz Aldrin's visor, above the reflection of Neil Armstrong, is the planet Earth.

It is said that, from the surface of the Moon, the Earth is so small that it can be completely and utterly hidden behind a thumb held out at arms length. Everything that has ever happened, anything that you've ever known, so small that even from just 250,000 miles away, it's small enough to hide behind a finger.

>>2546184

By that time the sun will be close to dying. When stars are close to dying they expand. Our sun will expand to about 256 times what it currently is. That means that it will engulf earth whole.
You won't survive shit.

This is a picture of the space shuttle docking with the International Space Station (zoom in), during the 1/4 when they passed in front of the sun. Picture taken from a cow pasture in France.

Space ships are great pool toys.

Saturn from the dark side.

i would be cool to be the first person to be on mushrooms or lsd on the moon

>>2546231
ok nigga anser me this

buzz aldrin shadow is fall towards the camera

yet in the helmet the shadow is falling away from the the camera

so fuck you

Look at the picture closely. Think about what you would see if you photographed yourself in a mirror. Now think about what you would see if that mirror was spherical in shape and also on the moon.

dammit

Apollo dump

>>2546286

LOL so that's what NASA does with our tax money
Space ship pool parties.
I'd imagine that bastard is full of beer

>>2546231
The Carl Sagan claptrack only works if the person you're talking to is stoned.

>>2546089
Here OP, its the same image, but three times bigger

>>2546318
The poor bastard holding the rope probably has a PhD.

That's pretty fucking crazy, to think there's all that shit out there. One of them looks like a flying saucer.

Best picture out of apoloo IMO

>>2546320
There was a gif form of this where it was saying how that image came from a tiny, empty portion of space, seemingly with nothing in it, that the hubble telescope analysed for a month. The large yellow galaxy in the corner there apparantely is so big it defies the laws of physics.

Pic, the earth, blows my mind

>>2546347
I stand corrected

>>2546338
Yeah, I think the Command Module is probably the reason people believe alien spacecraft would look the way we reckon they would. As it turns out, that's what real space ships look like.

Since most of us are in our late teen's or twenties the amazing thing is that we will most likely be able to go to the moon in out lifetimes now that Private space is taking off

>>2546388
I think you over estimate what private space is doing. They're not even planning on going to earth orbit.

Thanks. Yeah, I have that one but couldn't figure out how to make it under 2 megs or w/e the limit is without resizing it.

Also, everything in this thread is absolutely astounding to me.

>>2546320
One question though (a dumb one I'm sure), but why does the Earth look so tiny from the moon when the far smaller moon appears so large from Earth?

Also, a non space-related question that has been bugging me... Why does a ceiling/desktop fan put off cool air? Shouldn't it be the same temperature as the stagnant air?

You guys probably think I am a retard, so thank you for your patience.

This is the world's first proper space ship. It was the first vehicle in which man has ever flown into space and then returned safely to earth, where the craft can then be re-fueled and flown again.

The North American X-15 had enough energy to zoom to altitudes above the atmosphere. It flies so high and so fast that pilots experience weightlessness, and look out into the blackness of space. Yet, like its great great grandson, the Space Shuttle, it glides down through the atmosphere and lands on a runway just like any normal plane. This is significant, because during this time period (the late fifties, early sixties), men ventured into space in capsules, and the first human in orbit didn't even return to earth inside of his capsule (Yuri ejected from his capsule and landed separately using his own parachute). And of course none of these capsules were at all useful after they landed, if anything, they were lucky if they weren't utterly destroyed.

But the X-15 conquered space, and returned to gently kiss the earth.

Role
Commercial: various roles that put humans and cargo into LEO

Government: supply the International Space Station after retirement of the Shuttle

>In 2009 and 2010, Elon Musk has suggested on several occasions that plans for a manned variant of Dragon were proceeding and had a 2–3 year timeline to completion.

Do more research next time

>>2546421
The earth looks bigger from the moon than the moon looks from earth. We tend to over-estimate how big the moon looks in the sky, because of its brightness and prominence.

>>2546441
Also SpaceX has with only 60% of the money it costs to launch the space shuttle once. Built from scratch a new rocket that can carry more into earth orbit at 1/10 of the cost, and a fully built spacecraft that can do anything the governments spacecraft can but but it cost 8 billion and its only half done. Compared to the dragon which cost around 300 million

Capitalism is the greatest force for technological advancement

>>2546421
> Why does a ceiling/desktop fan put off cool air
It doesn't, it creates a movement of air causing the hotter air with a lower density to rise and the cold, dense air to fall meaning the room feels colder.

>>2546454 Capitalism is the greatest force for technological advancement

You're going to stick that in every thread?

>>2546454
>Capitalism is the greatest force for technological advancement
Not when it comes to doing something there is no profit in.

Moon landing was fake. No human could survive passing though the Van Allen radiation belt without being cooked alive. Particularly, since the shielding required to even attempt such a feat was not present on any of the Apollo craft. If it was, even the massive Saturn 5 rocket they used, wouldn't have enough thrust to break out of orbit.

>>2546491
mad

>>2546454

coz reinventing the wheel is very expensive to do

>>2546491
nah bro

>>2546150
Nobodys implying that the universe is thinking, just that small scale things tend to translate weirdly into extremely large scale things

It's called foam physics, look it up

>>2546491

The spacecraft moved through the belts in about four hours, and the astronauts were protected from the ionizing radiation by the aluminium hulls of the spacecraft. Furthermore, the orbital transfer trajectory from Earth to the Moon through the belts was chosen to lessen radiation exposure. Even Dr James Van Allen, the discoverer of the Van Allen radiation belts, rebutted the claims that radiation levels were too dangerous for the Apollo missions.[67] Plait cited an average dose of less than 1 rem (10 mSv), which is equivalent to the ambient radiation received by living at sea level for three years.[68] The spacecraft passed through the intense inner belt and the low-energy outer belt. The total radiation received on the trip was about the same as allowed for workers in the nuclear energy field for a year.[69]

The radiation is actually evidence that the astronauts went to the Moon. Irene Schneider reports that 33 of the 36 Apollo astronauts involved in the nine Apollo missions to leave Earth orbit have developed early stage cataracts that have been shown to be caused by radiation exposure to cosmic rays during their trip.[70] At least 39 former astronauts have developed cataracts; 36 of those were involved in high-radiation missions such as the Apollo missions.[71]

>>2546482
yeah and government is bad at doing things when it takes a long time because of the swinging opinions of congress

No system is perfect but capitalism is the best by far

>>2546482
>Implying that war isn't the greatest driving force behind technological advancement

>>2546480
Problem liberal?

stay away from my science and R&D your bureaucracy will just fuck it up

>>2546578
>implying its not private contractors that do the actual research for the government

The difference between a civilization with suborbital capability and one without is the distance from Germany to England. Were it not for this huge distance that needed to be covered, the V-2 would have never lifted off the pad to become the first human artifact to enter space. Near the end of the war, there were already V-2s with names like "Washington DC" - the development of the ICBM was underway.

The difference between a spacefaring civilization and one that never achieves spaceflight is the distance between the USSR and the US. Were it not for this distance, ICBM development never would have been funded. The powers that be wanted a way that they could deliver a nuclear warhead to America, and it just so happens that the amount of power needed to accomplish this feat also happens to be sufficient to send a small payload to orbit.

On an unrelated note, I really love the Block 1 design of the Command Module. It looks so cool. It's probably the most futuristic, flying saucer-like design of the whole space industry.

Absolutely loving the Apollo dump.

Man... I would love to learn what its like to see the earth so small, to be so far away from it that you can't help but perceive it as just an object in space.

What you learn from observing our solar system is that yes there is lots out there. Many planets, and on just one of them there is just as much complexity, distance and land that we have here if not more so (depending on the planet we choose). But... the Earth is unique. There isn't anything close to what we have here.

I'm not an environmentalist by any means. I love my automobiles, and I believe a certain amount of pollution is going to happen as a result of human action. Regardless respect is due. There is nowhere else we can go, there is no where else that will feel like here. This is our home.

>>2546639
This is our home.

And this is the only vehicle aboard which men have ever truly left this home. The only vehicle by which men have ever broken free from the grip of the earth, to travel to another planet. The Saturn V is the only thing of its kind. It is humanity's only method of interplanetary transport. And, seeing how the key to our immortality is in space, being able to sustain ourselves beyond the surface of our planet, maybe even travel to others, the Saturn V represents not only our past, but our future. Our future systems of interplanetary transportation will look back on the Saturn V as the reason for their existence, and those humans that fly in them will see it as the turning point in human existence.

>>2546670
And to think, we could have built an Orion at about the same time or sooner.

>>2546670
It looks amazing when you let one of these off underwater.
