The Galaxy and the Quasar
Explanation:
Is the
galaxy in the center connected to the
quasar on the upper right?
Disagreements about systems like this have raged for
decades and have been used to challenge the
foundations of
modern cosmology.
Some believe that the quasar
Markarian 205 was recently ejected from galaxy
NGC 4319,
indicating that the high redshift of
Markarian 205
is not indicative of its
distance.
Most astronomers have come to believe, however,
that the two are not physically associated, and that the high
redshift of Markarian 205 indeed indicates that it
lies across our universe.
In this predominant view, as with a
tree branch that happens to point toward the
Moon,
their juxtaposition in the
above image is just coincidence.
