M42, the Orion Nebula, is one of the brightest nebulae and is visible to the naked eye in the night sky. Lying about 1350 light-years away, it can be found up above Orion’s Belt in the constellation of Orion. Photo by MPAS member Nik Axaris

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.
Still looking south, you can find the South Celestial Pole by intersecting two imaginary lines: one an extension of the long axis of Crux, and the other at a right angle to the line joining the two pointer stars, Alpha and Beta Centauri.
At this time of the year, the two main stars of Gemini, Castor and Pollux, can be found sitting in the north. The constellations Orion and Taurus are also on show. In the south you will find the Large and Small Magellanic Clouds. Meanwhile, Leo the Lion is steadily rising in the northeast.
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. Mars is also visible in the night sky, positioned near the first quarter moon on February 19, then within binocular distance of the Pleiades cluster – aka M45 or the Seven Sisters – on February 28.
The Mornington Peninsula Astronomical Society holds its monthly public stargazing night on the first Friday of each month at the MPAS Mount Martha Observatory at The Briars. 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. Tickets are limited and bookings are necessary, so don’t miss out!
