This galaxy has a little more mass than our Milky Way , detected on 2nd March of 2007 The “Comet Galaxy” is actually just one galaxy located in a distant galaxy cluster known as Abell 2667, located about 3.2 billion light-years from Earth.
It's named Comet Galaxy because shows a tail with a length of 600,000 light years. The main reasons of the Comet galaxy tails is the gas and stars of the galaxy are being stripped away by the tidal forces of the cluster. The comet galaxy is currently being ripped to pieces. Moving through a cluster at speeds of greater than 2 million mph. Other factors adding to the damage of the galaxy are the cluster's scorching gas plasma. As the galaxy speeds through, its gas and stars are being stripped away by the tidal forces exerted by the cluster - just as the tidal forces exerted by the moon and Sun push and pull the Earth's oceans.
Scientists estimate that the total duration of the transformation process is close to one billion years. What is seen now in the Hubble image is roughly 200 million years into the process.Even though the Comet Galaxy’s mass is slightly greater than the Milky Way, it will lose all its gas and dust, and so not be able to generate stars later in life. It will become a gas-poor galaxy with an old population of red stars.
