Physics stuff from the week 14-20/5/12

[video] Don't miss the transit of Venus on the 5th June - it won't happen again until 2117!

Did you notice that asteroid, last Monday? No? It came incredibly close. Admit it - you were cacking yourselves!

A great picture of an annular eclipse, which happens when the moon's too close to fully obscure the sun. This happened for the same reason as the recent 'supermoons' - perigee - where the moon's closest in its elliptical orbit around the Earth
Another great picture of a partial (annular) eclipse, seen from Manila Bay, in 2009
Blazars - black holes that emit high-energy gamma rays - are heating up galactic dust, in some places to temperatures 100 times hotter than expected!

180 million years ago, during the Jurassic period, Earth's magnetic field flipped. This was one of the best-recorded geomagnetic flips, set, quite literally, in stone, in the rocks of South Africa

A wonderful picture of Cygnus X
