Violent
57. history of NGC 7714
NGC 7714 is a spiral galaxy 100 million light-years from Earth — a relatively close neighbour
in cosmic terms.
The galaxy has witnessed some violent and dramatic events in its recent past. Tell-tale signs
of this brutality can be seen in NGC 7714’s strangely shaped arms, and in the smoky golden
haze that stretches out from the galactic centre — caused by an ongoing merger with its
smaller galactic companion NGC 7715, which is out of the frame of this image.

Spiral
58. galaxy M81
This Hubble Space Telescope photo shows the majestic spiral galaxy M81.
In the midsts of this galaxy is the supernova 1993J which was recently found
to have a companion star which had been hidden in the glow of the
supernova for 21 years.
