On the Astronomy Show today I will be looking at some of the oldest galaxies which have been discovered by astronomers and incredibly they are orbiting our galaxy. These tiny galaxies were only revealed by astronomers using the latest equipment.
I will take a look at the night sky for the next few days with the night sky rapidly emptying of planets that have been with us all summer, soon only Mars will be visible. The end of August and the beginning of September is a transition period when the summer constellations are still high in the sky and with the autumn constellations just beginning to appear in the East.
The other regular features include the A-Z of constellations which is now at Sagitta the Arrow, which although a small group is one of the original Greek patterns. The Messier marathon has reached M73 which is not a cluster or galaxy but just a group of stars, I will explain on the show. The astronomical scrapbook which looks at anniversaries for this week includes The launch and safe return of the first animals in space, the Russian dogs Belka and Strelka in 1960, the discovery of the rings around Neptune in 1989 and the demotion of Pluto to a dwarf planet in 2006. All this plus the latest news from the astronomical societies in the north.
