Our winter galaxy

We reach the outer edge of the Milky Way as we hit the darker days

-

During the much colder months of the year, we can enjoy the longer hours of the night for extended tours and observatio­ns of targets in the night sky. Sadly, winter isn’t the best time of year to observe the Milky Way, as our planet looks towards the sparser regions of our galaxy – the outer portion of the disc.

However, that’s not to say that the Milky Way doesn’t hold a degree of wonder during the winter. Stars still clump together in the splash of white that’s characteri­stic of our galaxy as it laces through the constellat­ions Canis Major (the Great Dog), Monoceros (the Unicorn), Orion (the Hunter) and Puppis (the Poop Deck), bringing with it a spectacula­r selection of objects for stargazers to enjoy.

12 Messier 47

Constellat­ion: Puppis

Right Ascension: 07h 36m 36s Declinatio­n: -14° 30’ 00” Magnitude: +4.2

Minimum optical aid: Naked eye

It’s possible to view the coarse brightness of this open star cluster with the naked eye under very good night-sky conditions. However, the 50 stars found within the cluster won’t be resolved so easily without the assistance of a pair of binoculars or a small telescope. Messier 47’s swarm of young stars takes over a portion of the night sky around the same size as the full Moon.

13 Rosette Nebula and NGC 2244

Constellat­ion: Monoceros

Right Ascension: 06h 33m 45s Declinatio­n: +04° 59’ 54” Magnitude: +9.0 (Rosette Nebula), +4.8 (NGC 2244) Minimum optical aid: 10x50 binoculars

The Rosette is a giant ring nebula in Monoceros, and NGC 2244 is a young star cluster that has emerged from that nebula. Spotting the cluster is easy in binoculars or a small telescope, but seeing the nebula visually is difficult without a large telescope, dark sky and ultra-high-contrast filter.

14 Betelgeuse (Alpha Orionis)

Constellat­ion: Orion

Right Ascension: 05h 55m 10s Declinatio­n: +07° 24’ 25.42”

Magnitude: +0.2 to +1.2

Minimum optical aid: Naked eye

It’s not hard to spot the orange-red hue of the ninth-brightest star in the night sky. You can use a telescope or binoculars to view red giant Betelgeuse, but you’ll see nothing more than you can with the unaided eye.
