Well loads I’d imagine.
Gas planets are all over the place and we’ve a limited periodic table of (known) elements n all that

How they can tell what gases they are from millions of light years away is what I can never understand.

Something about rainbows. Planets are gay or something.

I mean look. How do they know??

This page gives an overview. Basically, they’re reading the light of the planet’s star as it passes through the atmosphere, using that to figure out the chemical composition.

Buncha viruses and hackers hiding out there.

This is unbelievable.

“The matter being pulled in toward this black hole, in the form of a disc, emits so much energy that J0529-4351 is over 500 trillion times more luminous than the Sun [1]. “All this light comes from a hot accretion disc that measures seven light-years in diameter — this must be the largest accretion disc in the Universe," says ANU PhD student and co-author Samuel Lai. Seven light-years is about 15 000 times the distance from the Sun to the orbit of Neptune.”

This is so fuckin cool.

They’ve managed to repair Voyager!

They should have tried turning it off and back on again.

It’s 24 billion kilometres away and only has a 68k computer. That’s little more than a calculator. It’s beyond impressive.


I need to learn how radio works. 22 hour turn around time between message sent and message received. That’s just insane. It’s 24 billion km away ffs

Yeah I was shocked at how fast radio waves move and the distance being so far it takes almost two days to send a message and get a reply.

I’ll try to post them tomorrow, but there are done crazy images of Io that have been released recently. Really beautiful

some cool things in this thread

Will remind you all again there’s an absolutely incredible documentary about Voyager called ‘the farthest’. It’ll blow your mind. Do look it up. Inspirational stuff.

I saw this on Instagram thought it was some flat earther bullshit. https://www.latimes.com/california/stor ... n-2024-pt5

Am I an asshole if I think that taking pictures of the Northern Lights using a filter on your phone because they can’t be seen with the naked eye doesn’t count as “seeing” the Northern Lights?
