February 1-7: Weather watcher. A new satellite will keep an eye on the weather -- not the weather on Earth, but out in space. We'll have details. And we'll also talk about a conjunction of the Moon and a bright star and planet.

February 8-14: The hunter. The giant constellation Orion stalks across the evening sky. It offers a shrinking giant, a giant stellar nursery, and a giant star that's not a nice place for life. Join us for details on this and more.

February 15-21: Weather without air. The Moon and many other bodies in the solar system are bare chunks of rock with no atmospheres -- yet they undergo constant weathering. We'll have details.

February 22-28: The unicorn. The celestial unicorn gallops high across the south on winter nights. It's home to some glowing clouds of gas and dust, as well as a dark cloud that's giving birth to new stars.
