August 2007

Galaxies galore! This month we focus on stellar cities; we have an interview with Martin Bureau about the formation of galaxies and we chat to Chris Lintott about a website which will allow everyone to help sort a million of them. We also get the latest news from Megan and Ian Morison tells us what we can see in the night sky this month.

The night sky for August 2007

Ian Morison tells us what we can see in the night sky from northern latitudes during August 2007. In the south, as the sun is setting, we have the constellations of Scorpius and Sagittarius. Jupiter is between the two in the large constellation of Ophiuchus. Moving upwards you reach Hercules with the four brightest stars making up the Key Stone. Moving up to the right, you can see globular cluster M13 with binoculars or a small telescope. To the right is Corona Borealis and Arcturus to the right of that. As last month, we also see the three stars of the summer triangle. Many of the planets are either in front of, or behind the Sun so are not really visible. Jupiter is probably only at around 10-16 degrees elevation for much of the UK. Mars is still only rising at around midnight but is reasonably bright and gets its closest to the Sun on August 19th. Highlights include the Perseid meteor shower and asteroid Vesta. The peak of the Perseids is 11-13th August which coincides with the new Moon on August 12th so viewing should be good. Vesta will be close to Jupiter, so should be easier to find towards the end of the month.
