![]() Bright new comet graces evening sky HARVARD-SMITHSONIAN CENTER FOR ASTROPHYSICS NEWS RELEASE Posted: March 23, 2002
No telescope is necessary to look at this beautiful visitor as it swings around the Sun and heads back to deep space. The comet has brightened to naked-eye visibility, but is easiest to see through binoculars. A casual glance will show the bright, starlike nucleus surrounded by a fuzzy cloud of dust and gas called the coma. The comet's tail streaks away from the Sun, pointing nearly straight up from the horizon. To find Comet Ikeya-Zhang, look in the western sky shortly after sunset. A red point of light about 18 degrees up in the sky is the planet Mars. (An outspread hand at arm's length covers about 15 degrees, so Mars is a bit higher than one hand-span.) To the right of Mars are two bright stars in a nearly vertical line. The comet is at the same height as Mars, to the right of the two bright stars about as far again as the distance from Mars to the stars. Headquartered in Cambridge, Massachusetts, the Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. CfA scientists organized into seven research divisions study the origin, evolution, and ultimate fate of the universe. ![]() |
