It Came From Oort
Comet Pan-STARRS may soon be visible to the naked eye. Scientists predict this icy body will be observable in the night sky next month as it loops around the sun and passes within 100 million miles of our planet. The comet is thought to have come from a distant region of space, beyond Pluto, known as the Oort cloud. Back in Oort, it was just another hunk of floating cosmic debris—a frozen cocktail of volatile gases and stellar dust. But as the object neared the inner solar system, heat and energy from the sun transformed its anatomy, adding a long tail to its defunct shape. The best time to see Comet Pan-STARRS is in mid-March, when it will appear in the western sky just after sunset. Watch the video to learn more about this comet and its journey through space.
A new comet may light up the night sky in March 2013.

In the night sky, the comet will potentially appear as bright as the stars of the Big Dipper.
These first images taken of the comet show it traveling through space.
The comet was first observed in Jun. 2011 by the Pan-STARRS telescope (above) on Mount Haleakala, Hawaii.
