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.

“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.”

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.

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?
