February 2012

     Well, the weather has not really been cooperating with us much here in southwest Georgia. Sometimes we can sky watch, some times we cannot. For the times the sky is clear, though, see if you can catch a glimpse of some of these things.
     The moon will be full on the 7th and new by the 21st, so there will be better sky watching towards the end of the month.
     The sun gave us quite a few powerful flares in January. This may continue through February.
     There are no regular meteor showers in February, although you may still catch a random “falling star” or two.
     One of the best constellations to observe this month is Gemini, the twins. Start by finding Orion, then look for two bright stars up and to the left. Only two deep space objects reside here: the open cluster M35 and NGC 2392, the “Eskimo” nebula.
     Most of the stars in Gemini are very faint, but Castor and Pollux are noticeably bright. Pollux is a K0III orange sub-giant that is only 33 light years away. It is a beta star, but is actually brighter than the alpha star. Castor, on the other hand, is actually several stars. This binary system has 6 stars all orbiting each other, and the two brightest stars (A1V/A2Vn) are both A class dwarves.
     Some other notable objects that were discovered in Gemini are Uranus and Pluto. You would need a pretty high-powered telescope to see them, however. The sky this month is dominated by the two brightest objects in the sky besides the sun and moon: Venus and Jupiter. Venus is setting now around 10:00pm, and Jupiter is starting this month in conjunction with the moon and Pisces. Also look for Mars rising just after 10:00pm close on the heels of Leo the lion.
     If you have any questions about these or any other subjects in astronomy, join us on the 3rd Tuesday night of each month for our Astronomy Series in the Wetherbee Planetarium at Thronateeska Heritage Center.
