Comet ISON was a sun-diving comet, destroyed by the sun's heat as it grazed near the sun on Thanksgiving last year.  

The comet's movement excited astronomers because it was one of the first times a sun-diving comet could be easily tracked in the sky, both from Earth and satellites, on a journey towards the sun. 

Now you can pick your favorite picture of ISON in a contest sponsored by the National Science Foundation.

Comet ISON was discovered in September 2012 by two astronomers in Russia. 

The comet gets its name from by the International Scientific Optical Network (ISON).

The Russian astronomers found the comet using a telescope in the ISON partnership, which spans about 30 telescopes in 10 countries.

After the first detection, astronomers looked through past space images and discovered the comet was seen by the Mount Lemmon Survey in December 2011. 

In June 2013, Comet ISON moved behind the sun and out of view from Earth.

According to, an amateur astronomer, Bruce Gary, in Hereford, Arizona was the first to spot Comet ISON after it emerged from behind the sun in August.

Far away from city lights, Gary operates two powerful telescopes in two separate structures.

ISON got as close as around 730,000 miles, which in space distance is a close call!

These images were captured from NASA's Solar and Heliospheric Observatory (SOHO).
