LUNAR ECLIPSE AND MARTIAN CONJUNCTION: Friday, July 27th, is a big night for astronomy. Mars will be at opposition–directly opposite the sun and making a 15-year close approach to Earth. Also, Mars and the Moon will be in conjunction–less than 10 degrees apart. And best of all, the Moon will pass through the shadow of Earth, producing the longest lunar eclipse in a century–visible everywhere except North America. What a night!
