ISON in 43-minute..........

The Hubble telescope observed comet ISON over a 43-minute span and capured a sequence of images of the fast moving comet. The comet is traveling at 48,000 miles per hour and covered 34,000 miles in just those 43 minutes, or 7 percent of the distance between Earth and the moon.

As the comet warms as it moves closer to the sun, its rate of sublimation (a process similar to evaporation in which solid matter transitions directly into gas) will increase. The comet will get brighter and its tail will grow longer. The comet is predicted to reach naked-eye visibility in November.

The comet is named after the organization that discovered it, the Russia-based International Scientific Optical Network.
