The Maryland Science Center is throwing a farewell party at 8 p.m. tomorrow for Comet Hale-Bopp, which is leaving the inner solar system for a 3,000-year tour of deep space.
The comet is still visible in the northwest sky after sunset and will continue to be so for several more weeks. But it is racing away and will get harder to see in the glare of a waxing moon and setting sun. The moon's crescent and the planet Mars will also be visible, weather permitting.
The Baltimore Astronomical Society and science center staff will be available with telescopes and explanations. For information, call 410-545-5918.
