VOLCANO WATCH: Alaska's Mount Redoubt volcano is rumbling and geologists expect it to erupt "within days." The last time an Alaskan volcano blew its top (Kasatochi in August 2008), about a million tons of ash and sulfur dioxide flooded the stratosphere, causing fantastic sunsets around the northern hemisphere and possibly reducing Earth'stemperature by a fraction of a degree. More SO2 is in the offing. Stay tuned for updates.

Greetings, fellow SkyWatchers! The Moon is back again, but what a terrific target for winter studies. Why not get out your binoculars and telescopes as we take a look at strange and unusual places like the Serpent Sea, the Marsh of Sleep and the Lakes of Time, Death and Dreams? If you haven't wished upon a star lately, then there's a serious reason to take a look at Sirius this weekend! Step outside in the dark with me where we'll explore a little history, a little mystery, and just plain have us some fun…
Friday, January 30, 2009 - Tonight’s early evening Moon is high enough to warrant study. During the last lunar cycle, we reviewed maria large enough to be seen unaided, but many more can be revealed telescopically. Magnify the Crisium region and let’s look around. Along the eastern side near the lunar limb is Mare Marginis, whose position between the nearside and farside will never allow us to see more than a thin gray line. Thanks to the lunar orbiters, we know it has an irregular border and shallow lava fill, which lead scientists to believe Marginus wasn’t created from an impact. Located southeast is Mare Undarum , the ‘‘Sea of Waves.’’ This highly elevated part of the Crisium basin is about the size of Massachusetts, and it probably filled with lava around the time of the Imbrium impact. Northeast, and separated by a mountain range, is Mare Anguis, or the ‘‘Serpent Sea.’’ This Vermont-sized area of lunar landscape formeddifferently and may be home to a vast number of lava tubes.
