Comet Discovered Hiding in Plain Sight
September 12, 2013
For 30 years, a large near-Earth asteroid wandered its lone, intrepid path, passing before the scrutinizing eyes of scientists while keeping something to itself: 3552 Don Quixote, whose journey stretches to the orbit of Jupiter, now appears to be a comet.

Bright Comet in the Evening Sky
March 08, 2013
Skywatchers in the northern hemisphere should enjoy a rare treat in the next few weeks, as Comet C/2011 L4 PANSTARRS enters the evening sky. Although the brightness of comets is notoriously difficult to predict, it looks as though this object may even be visible to the naked eye in the second half of March.

Comet PANSTARRS Rises to the Occasion Mid-March
March 07, 2013
Comets visible to the naked eye are a rare delicacy in the celestial smorgasbord of objects in the nighttime sky. Scientists estimate that the opportunity to see one of these icy dirtballs advertising their cosmic presence so brilliantly they can be seen without the aid of a telescope or binoculars happens only once every five to 10 years. That said, there may be two naked-eye comets available for your viewing pleasure this year.

New Evidence That Comets Could Have Seeded Life On Earth
March 05, 2013
Its among the most ancient of questions: What are the origins of life on Earth? A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life.
