Supermassive black holes grow with surprising speed, scientists find

NASA also found what they believe is the youngest black hole in the Milky Way galaxy.

The asteroid isn't the only thing stargazers will be watching Friday.

Black holes are back in the news, darkening our little corner of the universe.

On Tuesday, space.com reported that a new study found that giant black holes gobble up matter even more quickly than was believed. The study said supermassive black holes are growing with surprising speed.

Supermassive black holes are found at the center of most, and potentially all, galaxies, including our own.

The new study suggests they frequently eat up small bits of matter and that dramatic galactic mergers, previously thought to be their main diet, are actually rare snacks.

YOUNGEST BLACK HOLE

Also Tuesday, NASA said in a news release that its Chandra X-ray Observatory found a remnant of the youngest black hole in the Milky Way galaxy.

"The remnant … is about a thousand years old as seen from Earth and located about 26,000 light-years away," NASA said.

NASA believed the remnant was the product of a rare explosion that ejected matter at high speeds along the poles of a rotating star, rather than scattered in all directions, as is more common.

"It's a bit circumstantial, but we have intriguing evidence the … supernova (explosion) also created a black hole," said Daniel Castro, co-author of a study on the observation.

Scientists believe that because the supernova explosion did not leave behind a neutron star, the common byproduct of such an event.

"We looked for a neutron star, and we couldn't find anything," study co-author Laura Lopez said in a blog post.

"This result means that these exotic explosions can happen within our own galaxy, and further study of (the supernova remnant) will give great insights into how these awesome events come about," she said.
