On February 15th, a small asteroid plunged into Earth’s atmosphere over Russia, causing damage and injuries. Nobody saw it coming. The same day, astronomers expected asteroid 2012DA14 to make a very close, but harmless, approach to Earth. Both events captured media attention worldwide. It was an educational opportunity not to be missed!

Getting Ready For Comet PanSTARRS

In a few days, we in the Northern Hemisphere will be graced by what could be the brightest comet since the 1990’s. Discovered on June 6, 2011 by the 1.8 metre Panoramic Survey Telescope and Rapid Response System or PanSTARRS, this (then) 19th magnitude smudge is on a close encounter with the Sun. Officially catalogued as C/2011 L4, our interstellar visitor will be at its predicted brightest at third magnitude or brighter around March 6 or 7.

Today is the anniversary of Nicholas Copernicus' birth (1473 February 19), and Google marked the event by creating a animated doodle of the heliocentric (Sun-centred) Copernican system.

 

The asteroid 2012 DA14 will make a record-setting approach to earth mid-afternoon on February 15th, 2013. Recently discovered by Spanish astronomers at the Astronomical Observatory of Mallorca, this 45 metre asteroid is the size of half a football field, and its 130,000+ tonnes will be speeding past Earth at 28,100 km/h.
