US astronomers spot massive, record-setting stellar-mass black hole
The massive newcomer beats the previoushole discovered October 17 in the M33 galaxy that has 16 times the mass of our Sun, the US space agency said.
Like the much larger, supermassive black holes found at galaxy centers, stellar-mass black holes have such powerful gravity fields that not even light can escape them. Astronomers estimate their mass by measuring their gas emissions and the gravitational effect on the stars they orbit.
This is really great in the field of Astronomy! What can I say?
