Markarian's Chain of Galaxies
Explanation: Across the heart of the
Virgo Cluster of Galaxies
lies a striking string of galaxies known as Markarian's Chain. The chain,
pictured above
, is highlighted on the lower right with two large but featureless
lenticular
galaxies,
M84
and
M86
, and connects through several large
spiral
to the upper left, including
M88
. The home
Virgo Cluster
is the nearest
cluster of galaxies
, contains over 2,000 galaxies, and has a noticeable gravitational pull on the galaxies of the
Local Group of Galaxies
surrounding our
Milky Way Galaxy
. The
center
of the
Virgo Cluster
is located about 70 million
light years
away toward the
constellation
of
Virgo
. At least seven galaxies in
the chain
appear to move coherently
, although others appear to be superposed by chance. The
above image
is just a small part of a mosaic dubbed the
Big Picture
taken by the
Samuel Oschin Telescope
at
Palomar Observatory
, in
California
,
USA
. A mural of the Big Picture will be displayed at the newly renovated
Griffith Observatory
near
Los Angeles
, California.
