Hey amateur astronomers: Want to help measure the effects of light pollution on a global scale? From Wednesday 3 March (that's tomorrow) to Tuesday 16 March, participate in the GLOBE at Night project.

It's really very easy. All you have to do is go outside every evening after sunset (between 7 and 10 PM), look for Orion, eyeball the magnitude of its brightness, and report your observations on the site linked above. The site gives you all the information you need to find your latitude & longitude, to locate the constellation and to evaluate the brightness of the stars. I'll be doing this from the Huxley building at Imperial College London (Lat: 51.49915066919835 Long: -0.17953097820281982) and from my home in Cambridge.

Saturday's Chile earthquake was so powerful that it likely shifted an Earth axis and shortened the length of a day, NASA announced Monday.

By speeding up Earth's rotation, the magnitude 8.8 earthquake—the fifth strongest ever recorded, according to the USGS—should have shortened an Earth day by 1.26 millionths of a second, according to new computer-model calculations by geophysicist Richard Gross of NASA's Jet Propulsion Laboratory in California.

For comparison, the same model estimated that the magnitude 9 Sumatra earthquake in December 2004 shortened the length of a day by 6.8 millionths of a second.
