Comet LoveJoy! Discovered in August of 2014, Comet Lovejoy is currently sweeping north through the constellation Taurus, bright enough to offer good binocular views. Glowing softly with a greenish hue, Comet Lovejoy passed closest to planet Earth on January 7, while its perihelion (closest point to the Sun) will be on January 30. Classed as a long period comet, it should return again ... in about 8,000 years.

Image of Comet Lovejoy taken Saturday, January 10, by Dr. Bill Cooke. Image is a 3 minute exposure using the iTelescope T3 refractor. At the time of this image, the comet was some 45 million miles from Earth.
