While it may not be "entering like a lamb," March is ushering in some excellent times to see planets in our solar system - starting with Mercury. Normally overshadowed by the sun, Mercury is currently at its greatest elongation from the sun's glare. Just after sunset on Mar. 5 will be the best chance of the year to see Mercury through a telescope, but to the unaided eye it will appear as only a tiny dot in the sky.

On Monday, Mar. 5, NASA planetary scientist Renee Weber answered your questions about Mercury via live Web chat. The chat featured a color Ustream view of Mercury, Venus, mars, Jupiter and the moon from a telescope located at the Marshall Center in Huntsville, Ala.
