 Sky looking North on Wednesday January15 as seen from Adelaide at 22:17 ACDST (90 minutes after sunset, click to embiggen). 

 Orion is prominent in the mid sky.  Below Orion is Bright Jupiter, forming a triangle with Procyon and Betelgeuse.

 

 

 

 

 

 

Similar views will be seen from the rest of Australia at roughly the equivalent local time (90 minutes after sunset). 

Stars:

 January nights are dominated by the summer constellations of Taurus the Bull, Orion the Hunter and Canis major, Orion’s hunting dog. 

Orion is probably the most iconic of these, with Orion’s belt and sword known as the “saucepan” to most Australians.   Orion is almost due north an hour and a half after sunset when the sky is fully dark. Deeper into the night they are seen further northwards. They also travel further north later in the month.

To the Boorong people of north-western Victoria the belt and sword (and where is the belt and sword in relation to the ‘saucepan’ ) were Kulkunbulla, two dancing youths. 

If you are out in the country under dark skies, the stars of the sword look misty. This is the great Orion nebula, an astrophotography favourite. While you will not see the same detail with your eye as long exposure photographs, even in binoculars you can see the general shape of the great nebula 
Above the saucepan is the blue-white star Rigel, while below is the red super giant star Betelgeuse, which marks Orion’s shoulder. 

To the north of Betelgeuse is another red star, Aldebaran, which is the the eye of Taurus the bull, with the V shaped group of stars, the Hyades, next to Aldebaran forming the bulls head. Below Orion is Bright Jupiter, forming a triangle with Procyon and Betelgeuse.

The Christmas holiday season will be a fantastic time to explore our skies.
