Observing the southern skies this month you will find two stellar beacons shining away high in the sky. These are the two brightest stars in the night sky — Sirius and Canopus.
The waxing moon will be seen close to Mars in the morning of February 19, extremely close to Jupiter in the morning of February 20, and close to Saturn in the morning of February 21. On February 27 the waning crescent moon will appear close to Venus. Then on February 29 Mars will be close to globular cluster M22, which is an elliptical globular cluster of stars in the constellation Sagittarius, near the galactic bulge region, and is one of the brightest globulars that is visible in the night sky.
This 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 Mornington Peninsula Astronomical Society will be holding its monthly public stargazing night on Friday, February 7, at the MPAS Observatory at The Briars in Mount Martha. It starts at 8pm with a multimedia talk and Q&A before moving outside to view the moon, planets, stars and clusters, all through a wide array of telescopes supplied by the society and members. These nights are great fun for the whole family.
Then on February 19, Professor Ilya Mandel, from Monash University and chief investigator of the ARC Centre for Excellence in Gravitational Wave Discovery (OzGrav), will be speaking on gravitational wave astronomy, with the general public welcome to attend.
