Too Close to a Black Hole
Explanation: What would you see if you went right up to a black hole?
Above
is a
computer generated
image highlighting how strange things would look. The
black hole
has such strong gravity that light is noticeably bent towards it - causing some very unusual
visual distortions
. Every star in the normal frame has at least two bright
images
- one on each side of the
black hole
. Near the
black hole
, you can see the whole sky - light from
every direction
is bent
around
and comes back to you. The
original background map
was taken from the
2MASS
infrared
sky survey, with stars from the
Henry Draper
catalog
superposed.
Black holes
are thought to be the densest state of matter, and there is
indirect evidence
for their presence in
stellar binary systems
and the centers of
globular clusters
,
galaxies
, and
quasars
.
