Scientists Caught Black Hole Swallowing Star
Washington : Astronomers have caught
black holes in the act of murdering stars before. But a study published
Thursday, 26th November 2015, in Science claims to have caught a step in the crime that has remained
elusive until now.
In addition to catching evidence of the star's destruction -- an inevitable
death caused by the massive, inescapable gravitational pull of a dense
supermassive black hole -- the scientists saw a hot flare of matter escape from
the scene of the crime.
You can basically think of it as a hot plasma burp.
The researchers say this is the first time anyone has successfully picked
up the radio signal produced by this jet of escaping matter. These black hole
jets have been seen before, but they've never been directly linked to a star
being torn apart -- and the phenomenon remains pretty mysterious.
"These events are extremely rare," study author Sjoert van
Velzen, a Hubble fellow at Johns Hopkins University, said in a statement.
"It's the first time we see everything from the stellar destruction
followed by the launch of a conical outflow, also called a jet, and we watched
it unfold over several months."
The deceased star was quite similar to our own, but sat a staggering 300
million light years away. It was done in by the type of supermassive black hole
thought to sit in the center of most galaxies -- including our own.
Ohio State University scientists were the first to catch the murder in
progress using an optical telescope, which they announced online in 2014.
Along with researchers from the University of Oxford, van Velzen used
different telescopes to gather optical, radio, and X-ray signals from the event
as it unfolded. The researchers hope that they'll be able to catch more black
hole burps in progress, so they can figure out the exact mechanism behind the
purge.
We still have a lot to learn about black holes. Luckily, NASA has dubbed
November 27 "Black Hole Friday.
