It’s impossible to comprehend how something with 1,3-1,4 the mass of the sun can fit into something only 26km wide. I can hardly fit all my stuff into my luggage when I travel. This might be a stupid question, but are the pictures actual photos of the star or is it computer-generated based on data?


That picture is up there with the black hole from April. Astonishing


This is amazing and groundbreaking


Wow! I would have been very comfortable betting $1,000 that this would not be possible within 30 years.
