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.” https://www.eso.org/public/news/eso2402/ |

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 |

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. |
