We're back! Time to get back to our weekly schedule. Well it looks like we're safe from any impact possibilities from the asteroid Apophis as it performs it's flybys in both 2029 and 2036. Astronomers have also developed a new way to measure black holes and we look into the question of whether or not gravitinos are dark matter.
