Skywatching in 2010


I found a great article in Space.com about some interesting events to watch out for this year.
From the article:

Jan. 15 – Solar Eclipse

An annular (ring) eclipse of the sun will take place over parts of Africa, India and China. Because the moon is near apogee (its farthest point from Earth in its orbit) and the Earth has just passed perihelion. So the moon appears much smaller than average, and the sun somewhat larger than average. The moon's circle is only about 92 percent as wide as the sun; so 4 percent of the sun's width shows on each side of the moon. Thus, the annular phase lasts a maximum of 11 minutes and 8 seconds. This is a very long duration indeed: nearly half as long as some people got to watch last July's total eclipse. According to eclipse expert Fred Espenak of NASA's Goddard Space Flight Center, this is the longest annular eclipse of the 3rd Millennium – its duration will not be exceeded until the year 3043!

There is much more to see this year so get your telescopes ready!
