Earth and Sky shows Tonight’s Sky at http://www.earthsky.org/skywatching/
You can see Mars in the night sky, as it passes by the constellation Orion and the Pleiades star cluster, which is also called the Seven Sisters because only seven major magnitude stars can be seen with the naked eye. There’s actually hundreds of stars in the cluster, that can be seen with a telescope and time exposure images.
Also of interest, I’ve updated my blogroll to include this great site, along with a few others that share this blog’s focus on astronomy and space exploration.
