Where
are Quasars in the sky?

The above
photo was taken by the
Hubble Telescope.
This is a quasar jet, also
emitting from black hole, 3C-273
Where would one
find a quasar? Look far away in an old galaxy,
quasars are some of the most ancient cosmological
phenomenons
out there! Though they stretch
thousands of times
further than the
limits of their own
galaxy, quasars aren't anywhere near us. It's
likely quasars died out long ago and all we're
seeing are ghosts of
ancient bright beasts.

This photo of a quasar from
black hole, 3C-273
was taken by the Chandra X-Ray Observatory
Quasars
aren't close to us, by any means. For
example, one quasar known as PKS 1127-145 is
ten billion light-years away from earth. The
pictures below are of the exact same space,
one in optical light, and one in x-ray. All
of the galaxies in the first picture may
look close to each other in brightness, but
in the second you can clearly see which one
is the quasar. The jet coming out of PKS is
10 million light-years long, putting the
other galaxies to shame.
