Explanation:
What's happening to the big black hole in the center of our galaxy?
It is sucking in matter from a swirling disk -- a disk that is
magnetized, it has now been confirmed.
Specifically, the
black hole's accretion disk
has recently been seen to emit
polarized light,
radiation frequently associated with a
magnetized source.
Pictured here is a close-up of Sgr A*, our
Galaxy's central black hole, taken by
radio telescopes
around the world participating in the
Event Horizon Telescope (EHT) Collaboration.
Superposed are illustrative curved lines indicating
polarized light likely emitted from
swirling magnetized gas that will soon fall into the
4+ million mass
central black hole.
The central part of this image is likely dark because little light-emitting gas is
visible between us and the
dark event
horizon of the black hole.
Continued EHT monitoring of this and M87's central black hole may
yield new clues
about the gravity of black holes and how infalling matter creates
disks and
jets.
