Unusual Gas Filaments Surround Galaxy NGC 1275
Explanation: How were the unusual gas filaments surrounding galaxy NGC 1275 created? No one is sure. Galaxy NGC 1275 is the
central dominant galaxy
of the
Perseus Cluster of Galaxies
, a cluster with many member galaxies visible in the above image. In visible light,
NGC 1275
appears to show a
spectacular collision
between two distinct galaxies. The galaxy and cluster are also bright emitters of
X-rays
. The unusual gas filaments are shown above in a very
specific color
of light emitted by
hydrogen
, here artificially colored pink.
Possible origins for the filaments
may involve details of the collision between the two galaxies, or alternatively, interactions between a
galactic center black hole
and the surrounding
intracluster gas
. NGC 1275,
pictured above
, spans about 100,000
light years
and lies about 230 million light years distant toward the
constellation
of
Perseus
.
