Orion’s Belt is easy to spot. It is made up of three stars, Alnitak, Alnilam, 
and Mintaka.
Canis Major, the Great Dog, is the faithful companion who follows in 
Orion’s footsteps. 
Canis Major is dominated by the most brilliant star in the night sky, Sirius.
Sirius is actually a double system, containing a bright star and a much 
smaller and fainter companion.
It is a mere 8.6 light-years away.
Scanning with binoculars just below Sirius will reveal a lovely cluster of 
stars called M41. It contains about 100 stars, including several red giants.
Stars in clusters like M41 are bound to each other by gravity and are all 
about the same age.
From the left side of Orion’s Belt, look down to the Great Orion Nebula. 
Although barely visible to the naked eye, it is the brightest diffuse gas 
cloud in the night sky. (“Nebula is Latin for “cloud.”)
A small telescope unveils the details and grandeur of the nebula.
Embedded inside the Orion Nebula is the Trapezium, a group of hot young 
stars so brilliant they cause the surrounding gas to glow. 
This turbulent cloud of dust and gas is, in fact, a star nursery. In this 
maelstrom of activity, new stars are being born.

Venus rises before the Sun in the southeast to herald the coming of the 
winter dawn.

The night sky is always a celestial showcase. Explore its wonders from 
your own backyard.
