- In 1967 John Archibald Wheeler coined the term "Black Hole"
- Cygnus X-1 was the first solid black hole candidate in 1970
- Throughout the 1990s the Hubble Space Telescope found evidence that supermassive black holes may exist in the centers of many galaxies in the universe, including our own.
- Spaghettification: If you fell into a black hole, the atoms in your body would be turned into one long string of atomic spaghetti!
- Our Milky Way galaxy contains a super massive black hole that's about 3 million solar masses!
- To date, all studied galaxies contain a super-massive black hole at their center.

Black holes are objects with gravitational fields so powerful that nothing (including light) can escape from them. Black holes are formed when massive stars collapse to a point with infinite density and become a singularity.

Black holes are objects with gravitational fields so powerful that nothing (including light) can escape from them. Black holes are formed when massive stars collapse to a point with infinite density and become a singularity.
A supermassive black hole resides at the center of our galaxy, the Milky Way. Most galaxies contain super-massive black holes. The largest supermassive black hole is the size of 18 billion solar masses!

@CinSin143 Pulsars are neutron stars. They are between white dwarves and black holes in the end of star lifecycles. They are fucking rad.
