Imagine the Universe!

Look, There in the Sky!

In the Spring of 1996, comet Hyakutake made a spectacular run through the solar system. In a great surprise to high-energy astronomers, it proved to be a detectable source of X-rays! The strength of the X-ray emission and its rapid time variability were not expected. However, comets have long been a source of amazement to human kind. Whether viewed as omens of evil or as remnants of solar system formation, they are always a source of interest and awe.

Imagine the Universe is a service of the High Energy Astrophysics Science Archive Research Center (HEASARC), Dr. Alan Smale (Director), within the Astrophysics Science Division (ASD) at NASA's Goddard Space Flight Center.
