September 2009: Anomalous

September 2009

We're back from our summer break with an interview with Professor Rod Davies about anomalous microwave emission. As ever we have the latest astronomical news, what you can see in the September night sky, and your feedback.

The News

In the news this month:

Anomalous Emission

Professor Rodney Davies (Jodrell Bank Centre for Astrophysics) talked to us about anomalous emission and spinning dust.

The Night Sky

Ian Morison tells us what we can see in the night sky during September 2009.

Northern Hemisphere

Now becoming visible towards the south east in the early evening is Pegasus - the winged horse. If you start at the top left-hand star of the square of Pegasus - Alpha Andromedae - you curve up to the left two bright stars then turn sharp right, move one reasonably bright star and then carry on by just about the same amount to the fuzzy glow of the Andromeda Galaxy (M31). Another way to find Andromeda is to find the 'w' shaped constellation of Cassiopeia. The three bright right-hand stars form a 'v' which points down to the Andromeda Galaxy too. Heading left from Cassiopeia brings you towards the constellation of Perseus and between them is the Double Cluster in Perseus. Below the bright star Alpha Persei is the eclipsing binary Algol. Below Perseus is Pisces with Aquarius to the lower right and Cetus to the left.

The Planets


Southern Hemisphere

Looking to the north you'll see many stars that are also seen in the northern hemisphere. Looking south you'll see the lovely vista of the Milky Way. Due south is the south celestial pole with the Large and Small Magellanic clouds to the left. In the plane of the Milky Way, about a third of the way up from the horizon, you see Crux - the Southern Cross. If you look at the highest of those stars with binoculars, you'll find the nearby Jewel Box Cluster. Above that is the constellation of Centaurus. Take the lower of the two brightest stars, and then work your way to the west and you'll come to another bright star. If you carry on in that direction you should see a fairly bright fuzzy object which is globular cluster Omega Centauri.

Odds and Ends

Jamx mentions Microsoft gifting the Feynman lectures to the world.
