Cosmos with Cosmos Episode 4: Heaven & Hell
In which face the consequences of our own knowledge
Humans face the consequences of our own knowledge about the cosmos in this latest episode recap and analysis of Carl Sagan's classic series.
An update from University of Strathclyde researchers about the Planetary Society sponsored laboratory Laser Bees asteroid deflection project including a new laser and other lab equipment, and the start of new related projects.
For those wishing to bore into more details of our Laser Bees project itself, graduate student Alison Gibbings from the University of Strathclyde has sent their technical paper that resulted from the 2013 Planetary Defense Conference.
Planetary Defense Conference 2013 Part 3
Part 3 of Bruce Betts' wrap up from the Planetary Defense Conference 2013 focuses on the Laser Bees (asteroid deflection method) project and Laser Bees researcher Alison Gibbings.

State of Research and Videos to Watch
First part of a 3 part wrap up to April's Planetary Defense Conference: a very brief review of the status of research in asteroid threat related fields based on the conference, report on special activities at the conference, and links to video and audio related to the conference.
Partnering with our friends from The Planetary Society, the Space Generation Advisory Council (SGAC), whose members hail from all over the globe, is bringing you an update on our activities and something you can join in on—at least if you are a student or young professional aged 18–35.
Saving the Planet can be Exciting!

This week I'll be talking with NEOWISE principal investigator Amy Mainzer about moving objects that the WISE mission has spotted both inside and outside our solar system.
Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.
What We Know About the Russian Meteor Event [UPDATED]
We have the technology to provide warning about these potential disasters
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.
Continuing my writeup of notes from last week's Division for Planetary Sciences meeting: presentations on the risks of future asteroid impacts. How much risk do we face, and what are the appropriate actions to take in the face of that risk?
