Preliminary estimates show that the meteoroid was 15 meters wide and weighed roughly 8000 tons. The resulting airburst would have the equivalent yield of about a 1/2 megaton explosion.
A large meteor streaked through the skies above Russia on the morning of Feb 15th, causing a deafening sonic boom that shattered windows and injured hundreds.
Emily Lakdawalla and Courtney Dressing talked about just how common Earth-sized exoplanets may be in our neighborhood. Watch the replay here.

Hey planetary scientists! Many of you know that the Lunar and Planetary Science Conference (LPSC) is a great meeting in a venue that is perfect except for one thing: Internet access is positively lousy. So I'm really excited that a solution that I advocated to conference organizers is being adopted.
Join Casey Dreier and Emily Lakdawalla as they are joined by Dr. Meg Schwamb from Yale University. They will discuss the latest announcements from the American Astronomical Society 2013 conference and Dr. Schwamb's research in outer solar system bodies.
