Explanation:
In this stunning vista
recorded with the Hubble Space Telescope's
Advanced Camera for Surveys,
distant galaxies form a dramatic backdrop
for disrupted spiral
galaxy
Arp 188, the Tadpole Galaxy.
The cosmic tadpole
is a mere 420 million light-years distant toward the
northern constellation Draco.
Its eye-catching tail is about 280 thousand light-years long and features massive,
bright blue star clusters.
One story goes
that a more compact intruder galaxy crossed in front
of Arp
188 - from left to right in this view - and was
slung
around behind the Tadpole by their gravitational attraction.
During the
close encounter, tidal forces drew out the
spiral
galaxy's stars, gas, and dust forming the spectacular tail.
The intruder galaxy itself, estimated to
lie about 300 thousand light-years behind the Tadpole,
can be seen through foreground spiral arms at the upper left.
Following
its terrestrial namesake,
the Tadpole Galaxy will likely lose
its tail
as it grows older, the tail's star clusters
forming smaller satellites of the large spiral galaxy.
