Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth - Ptolemy

Diamond Rain

'The most common precipitation in the Solar System could be diamond rain.' I must admit that when I read that, my interest was piqued. Dr Kevin Baines of the University of Wisconsin-Madison and NASA's Jet Propulsion Laboratory reports that crystallised carbon rains down on the gas giants Jupiter and Saturn. What would Elizabeth Taylor say?

The Hefty Chelyabinsk Meteorite

Scientists can find out a lot of information from meteorites so it's precious stuff and extremely valuable. When the Chelyabinsk meteor exploded over Russia in February this year, some chunks landed on Earth. Luckily the largest piece landed in a lake, so it was recoverable. What's the half-a-tonne lump of space rock dredged up from the bottom of Lake Chebarkul on 16 October worth, I wonder?

November 2013 Diary Dates

Comet Encke and Comet ISON both reach perihelion this month (33.1 million miles and 1.1 million miles from the Sun respectively). Have you managed to see any of the four comets in the sky at the moment yet?

  • 03: New Moon
  • 03: Total Solar Eclipse visible only from the Atlantic Ocean and equatorial Africa
  • 05: Southern Taurids meteor shower peak, although it's usually drowned out by more Earthly fireworks

  • 15-18: Comet LINEAR passes by Arcturus (alpha Boötis)
