Black+Holes

=Black Holes​ = =By: Melina Tedrow and Caleb Lay = = Black Holes are massive, so dense that no light or other radiation can escape from it. They are infinilly dense and can swallow up anything that comes close to them, even light. Their mass is between 8 to 16 times the mass of the Sun. Types of black holes are Stellar, Einstein Cross, Galatic, Quasar PK S 0637-752, Seyfer NGC 1275, Centaurus A/NGC 5128. The distance across a black hole is 3.6 miles. A black hole has tons of gravity and is full of hot gas. Radio anstromoners long ago dedicated enormous jets of hot gas and energy shooting from some galaxies. = = = = = ==
