Astrophysicists are calling the gargantuan megastructure "Porphyrion," after a mythological Greek giant.
Galaxies usually become chaotic when they run out of star-making fuel, but this one is going out surprisingly quietly.
At just 300 light years apart, it's the closest duo yet discovered.
The highest-resolution ground-based observations by the Event Horizon Telescope is paving the way for the future of black hole astronomy.
A recurring tidal disruption event was predicted and then came to pass, giving the researchers a chance to predict the black hole's next meal.
Citizen scientists are invited to use a specialized app to sift through photos captured by powerful telescopes, searching for signs of neutron stars merging.
