I'm going to make a presentation about gliese 581. Any tips/recommendations?
Pic distantly related.

Make a presentation about how hyped up it is. Seriously. There will be far better candidates.

>>2919195
Well, considering that I can choose what solar system to make a presentation about (preferably not Sol, though), which one should I choose then?

Well, considering that I myself am interested a lot in gliese 581 as it's relatively nearby and has awesome planets, I think that I'll stay with it.

there's some cool new kepler planets i think

there's a binary system with a brown dwarf that's so cool it's about the temp of a cup of coffee and might even support an atmosphere, which really blurs the line between stars and planets

and then, you know, the rest of the universe

What, you mean another atmosphere that isn't 99.9% of the dwarfs mass?

>> No.2919270

>>2919261
haha, you know what i mean, water vapour and shit above it

"atmosphere" is the wrong word for it i guess

anyway i agree that you should pick a different system there are hundreds

Wouldn't the water vapour get sucked below due to the largely hydrogen and helium atmosphere? Y'know, buoyancy issues.

>The coolest of the pair, simmering away at just 100 degrees Celsius, is known as CFBDSIR 1458+10B, and is located 75 light years from Earth. For comparison, the temperature of the Sun's surface is over 5,500 degrees Celsius. “At such temperatures [100 degrees Celsius] we expect the brown dwarf to have properties that are different from previously known brown dwarfs and much closer to those of giant exoplanets – it could even have water clouds in its atmosphere,”

don't ask me, i can only count to potato

That means water ANYWHERE in it's tens of thousands of kilometers thick atmosphere. Most likely closer to the surfae, I would think.

Oh and as I was looking for brown dwarf artwork I came across this.

when i said "support an atmosphere" i should have said "have a more planet-like atmosphere"

and yeah those pictures are cool

Make sure your teacher isn't a fucking moron. I gave a presentation in highschool and brought up a point about how it takes x number of years for signals from Earth to whatever and he said "Oh so it's cosmic time travel?"

Nah, he's bro-tier.

Anyway, as I had to rush while making it I didn't watch this thread a lot and didn't see the recommendations of other solar systems. Thank you anyway, /sci/.
