Now is a good time to observe and admire the rich star fields of the Milky Way stretching across the southern skies. To scan these stars, you only need your eyes or a pair of binoculars. Look out for the Milky Way running through the constellations Crux, Centaurus, Musca and Carina in the east. Be sure to observe the Coalsack Nebula, a distinctive dark patch close to the stars of Crux, the Southern Cross. This dark nebula is a cloud of dust and gas about 600 light-years away. Also look for an open cluster in the constellation Carina known to astronomers as the Southern Pleiades (IC2602). It is visible to the naked eye, but binoculars show it twinkling away.
The two brightest stars in the sky this month are Sirius and Canopus. And two stunning constellations – Crux, the Southern Cross, and Centaurus, the Centaur – are also visible. A little way above them you will find the deceptive False Cross, sometimes mistaken for the true Southern Cross. The False Cross is formed by four stars in Vela and Carina.
The constellation Puppis, the Stern, sits in the night sky just north of the bright star Canopus and is wedged between the constellations Vela, Carina and Canis Major. Puppis is home to the open star clusters M46 and M47, which can be seen with a pair of binoculars.
