Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Ansky (black hole)?Typically > 20-25 solar masses
2. What is the black hole classification?Stellar black hole
3. What is the formation event?Core-collapse supernova followed by gravitational collapse beyond neutron degeneracy pressure
4. What is Ansky?Ansky is a stellar black hole, a very dense object that forms when a massive star dies. Its gravity is so strong that even light cannot escape, so it looks invisible.
5. How do scientists know Ansky exists if they can't see it?They study how nearby stars or gas move. If the motion is faster or curved in a strange way, it shows a huge invisible pull. They also detect bright X‑ray and gamma‑ray light from hot gas swirling around it.

Singularity: A point in spacetime where gravitational forces are predicted to become infinite, as theorized at the center of a black hole.
General Relativity: Einstein's theory describing gravity not as a force, but as a curvature of spacetime caused by mass and energy.
Gravitational Waves: Ripples in the fabric of spacetime, generated by accelerating massive objects, that propagate outward at the speed of light.
