The First Triple Quasar
In an announcement made on Monday at the American Astronomical Society conference in Seattle, astronomers confirmed that quasars can come in threes.
News from the AAS
About 3,000 scientists from around the world gathered Sunday in Seattle, Washington, for the 209th meeting of the American Astronomical Society. Hundreds of discoveries were announced on the conference’s first day. Here are few of the highlights.

The Year in Astronomy 2006
Remember when the solar system had nine planets? When the Hubble Space Telescope was doomed? And when Jupiter only had one red spot?
Celestial Omens
Go out at dusk to see Venus and the crescent Moon pair up. It is always a sight to behold when the brightest objects in the evening sky get together.
Life with a Red Dwarf
The commonest stars in the universe aren't very Sun-like — but they could still have life-bearing planets. However, those worlds aren't like anything you've ever seen. Imagine a home world where half of the planet basks in eternal day, the other cloaked in eternal night.
An Ancient Building Block of Life
Astronomers have long assumed that carbon-based molecules — essential for life as we know it — were among the building blocks of our solar system. Now they have the evidence to back their claims. The smoking gun came from measurements of the famed Tagish Lake meteorite.
A Reason to Rise
Most of us consider weekends a time for sleeping in, but skywatchers who get up before the Sun are presently in for a treat. A trio of planets will dance with the bright star Antares, and on the mornings of the 17th and 18th there will be a guest appearance by the waning crescent Moon. The performance is free, but clear skies and an unobstructed southeastern horizon are required.
Aurora Watch!
Talk about a red-letter night for astronomy. Not only are Geminid meteors still raining down from the skies, there is a major aurora alert in effect for Thursday and Friday. No telescope needed. Just get outside and look up.
Night Sky Magazine to Cease Publication
Sky Publishing has decided to stop producing Night Sky, its bimonthly magazine for beginning amateur astronomers. The March/April 2007 issue will be the last.
Best Meteor Shower of 2006
With only minor interference from the Moon, the Geminids should put on a great display late Wednesday night and Thursday morning. What's more, a major solar flare just erupted, providing a strong chance for a tremendous northern lights show on Thursday or Friday.
Flowing Mud on Today's Mars?
Newly released images from Mars Global Surveyor strongly suggest that liquid water could be flowing across the surface of Mars right now.
