Comet Galaxy

The Comet galaxy is a spiral galaxy in the constellation of Sculptor. 

The Comet galaxy is over a 3 billion light years away. This is a massive distance, considering that the distance of a 1 single light year is nearly 6 trillion miles. So that’s over 3 billion x 6 trillion miles. Its a long way away!



As the Comet galaxy is so far away, the galaxy unlike other galaxies that were discovered a long time ago, was discovered recently in 2007 by the Hubble Space Telescope. The galaxy has slightly more mass than our Milky Way galaxy. The young Blue stars spread out at the stem of the galaxy makes for the galaxy to look like a Comet hurdling through space.  

The Comet galaxy is very volatile and is moving at great speed while breaking up throughout space as it goes. The galaxy is likely to be totally ripped apart in about a billion or so years. It’s a long time away for that to happen though.
