Comet Lulin (C/2007/N3) should become visible this month. It is a new comet so it is tough to predict how bright it will get. Most experts are predicting it will brighten to magnitude 5 or 6. This means it should be an easy binocular target from the suburbs and a possibly naked eye target from dark sky.
The comet will go through Libra, Virgo and hit Leo this month. It will be best to look for it after midnight when it will be higher in the sky. It will be close to Spica on the 15th. It will be close to Saturn on the 23rd and close to Regulus in Leo on the 27th.
Space Shuttle Atlantis Launches on Final Mission to Hubble
Space shuttle Atlantis with its sevenmember crew launched at 2:01 p.m. EDT on Monday, May 11, from NASA's Kennedy Space Center on the final Hubble Space Telescope servicing mission.
Atlantis' 11day mission will include five spacewalks to refurbish Hubble with stateoftheart science instruments designed to improve the telescope's discovery capabilities by up to 70 times while extending its lifetime through at least 2014.
Shortly before liftoff, Commander Scott Altman thanked the teams that helped make the launch possible. "At last our launch has come along," said Altman. "Getting to this point has been challenging, but the whole team, everyone, has pulled together to take us into space."
