Ikeya-Murakami: The New Comet on the Cosmic Block

The animation below shows the motion of Comet Ikeya-Murakami on Nov. 13, 2010, captured with a New Mexico-based telescope operated remotely by NASA's Marshall Space Flight Centre. The images were taken near dawn and show the comet's movement over a period of 45 minutes. Each exposure was three minutes in length, and the faint angled streak around 0:10 in the animation is a satellite trail. At the time of these images, the comet was some 229 million miles away from Earth.

Newly discovered fast-changing comet visible in Small telescopes

A newly discovered comet that has caught the attention of skywatchers around the world appears to be undergoing some dynamic changes.
The comet, called Ikeya-Murakami (C/2010 V1), was first detected last week by amateur astronomers in Japan, but several other skywatchers have since been watching the icy wanderer's changing appearance over the last few days.
Russian astronomer Leonid Elenin, of Moscow, used the remotely operated ISON-NM telescope in New Mexico to observe the new Comet Ikeya-Murakami over the weekend.
