Our galaxy's youngest black hole? Could be... [View all]
The warped leftovers from a rare star explosion may be hiding the youngest black hole in our galaxy, a new study reveals.
The supernova remnant, called W49B, is about 1,000 years old as seen from Earth, and it is located about 26,000 light-years away. Scientists suspect it met an unusual demise.
"W49B is the first of its kind to be discovered in the galaxy," study lead author Laura Lopez of MIT said in a statement. "It appears its parent star ended its life in a way that most others don't." Lopez and her team unveiled a dazzling video tour of the supernova remnant during a Feb. 13 announcement.
Typically, when a star reaches the end of its life and explodes in a supernova, it shoots stellar material away from its center more or less evenly in all directions, creating a relatively symmetrical cosmic object.

Supernovas tend to leave behind an extremely dense spinning core called a neutron star, which often can be detected through X-ray or radio pulses. But scientists using data from NASA's Chandra X-ray Observatory found no evidence for a neutron star, which makes them believe a black hole might have formed in the supernova instead.
