February skies 2026

Northern sky on Friday, February 27  as seen from Adelaide at 21:22 ACDST (90 minutes after sunset, click to embiggen).  Jupiter is close to the nearly full Moon, forming a narrow triangle with Castor and Pollux and a broad triangle with the bright stars Procyon and Betelgeuse. 
 

The inset is the telescopic view Jupiter at this time.  

    

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

Sky looking North-west on Tuesday February 24 as seen from Adelaide at 20:56 ACDST (60 minutes after sunset, click to embiggen). 

The First Quarter Moon is clearly visible above the horizon close to he Pleiades cluster. the Lunar X and V may bee seen in a telescope or strong binoculars. The insets show the telescopic and binocular views at this time. 

 

 

 

 

Similar views will be seen from the rest of Australia at roughly the equivalent local time (60 minutes after sunset). 

Stars:

North western sky as seen from Adelaide at 21:41 ACDST (90 minutes after sunset). Similar views will been seen elsewhere in Australia 90 minutes after sunset.

February nights see the summer constellations of Taurus the Bull, Orion the Hunter and Canis major (Orion’s hunting dog) slip into the north-western sky.


Orion is still visible,  as are the Pleiades, a close grouping of six stars.   A line drawn westward through Betelgeuse, the red star that forms the shoulder of Orion, and Aldebaran brings you to the Pleiades.

Although faint, the Pleiades is pretty to the unaided eye, and delightful in binoculars. If you’re fortunate enough to have a decent telescope, you’ll be able to see a hint of the nebulous cloud that makes photographs of this cluster an astronomical icon. 


The Pleiades is also known as the Seven Sisters in European culture.  Interestingly, many Indigenous Australian groups also saw the cluster as women. The Boorong people of north-western Victoria called it Larnankurrk and described it as a group of women watching Kulkunbulla (the two dancing youths represented by the Saucepan of Orion’s belt).   However, the people of the Lake Albert area saw the Pleiades as a clutch of turkey eggs.


In February, you can also see a constellation called the “Southern Pleiades” (it’s only visible in the southern hemisphere).  It’s a lot less obvious to the unaided eye than the Pleiades themselves, but is truly beautiful in binoculars or a small telescope.  It’s made up of a cluster of stars around theta Carina, which also glories in the name Vathorz Posterior.

To find this small gem, look up from Acrux, the brightest star in the Southern Cross. The second bright star you come to is surrounded by a halo of dim stars, this is the Southern Pleiades. 
You can easily see the Pleiades and the Southern Pleiades from around an hour after sunset as they emerge from the twilight.


 As the night progresses the Pleiades sink into the west. In contrast, the Southern Pleiades rise higher above the southern horizon as February progresses but they will become harder to see due to moonlight.  


Mira:

 

North western sky as seen from Adelaide at 21:41 ACDST (90 minutes after sunset). Similar views will been seen elsewhere in Australia 90 minutes after sunset. The variable star Mira is above the western horizon and indicated by the circle. The inset is the binocular view of the Mira and the two obvious stars Zeta and Chi Ceti at this time (click to embiggen)

 
The variable star Mira (omicron Ceti) should start to brighten in February, rising from below unaided eye visibility to around magnitude 4 before peaking in March at around magnitude 3. It will be seen low above the western horizon when the sky is fully dark.
