Image descriptions:

1: Visualization of 2 interacting supermassive black holes. Text: Fascinating Facts About Black Holes

2: Illustration of a black hole encircled by warped stars & dark clouds of dust. Text: A black hole is an object with gravity so strong not even light can escape.

3: Illustration of a star exploding in a supernova. Text: Most black holes form from the collapse of a large star that dies in a supernova explosion.

4: A model star stretches as it approaches a black hole. Text: Stellar-mass black holes are three to dozens of times the mass of the Sun. Supermassive black holes contain millions to billions of times the mass of our Sun.

5: Simulation of the light from 2 supermassive black holes. Text: Two black holes can merge to make a larger one! Stellar-mass black holes can be created when two neutron stars merge.

6: Image of the supermassive black hole at the center of our galaxy. Text: The first time we saw a real image of a black hole was in 2019. The Event Horizon Telescope shared an image of the black hole at the center of galaxy M87, a supermassive black hole 55 million light-years away.

7: Hubble image of a starry sky with pockets of gas visible. Text: Astronomers think a supermassive black hole lies at the center of almost every galaxy, including ours!

8: Simulation of black holes distorting the starry background & light. Text: Black holes are not cosmic vacuum cleaners. They don’t suck matter in. From far away, their gravitational pull is similar to other objects of the same mass. But get too close, and you keep falling to its center and can never escape!

9: Graphic of photographs of 4 people on a background of out-of-focus purple and blue stars & gas. Text: Meet the black hole experts.
