Galaxy NGC 2997 and comet C/2012 V2 (LINEAR). Comets are bodies of ice and dust that enter the inner solar system from the outer solar system. As they approach the Sun,the heat boils the ice,producing a coma around the nucleus,along with a tail stretching out behind it. Comet C/2012 V2 (right) was discovered on 5 November 2012 by the LINEAR survey. It came to perihelion during mid-August 2013 and reached 8th magnitude,displaying a fine dust tail and a distinct greenish coma. Spiral galaxy NGC 2997 (left) lies 40 million light years from Earth,in the constellation of Antlia. This image was obtained on 29 September 2013 | |
