There is a lot to see in the southern skies this month with just the naked eye. Start off by looking for the Large Magellanic Cloud (LMC) west of the constellation Pictor, and the Small Magellanic Cloud (SMC) in Tucana. These are both irregular galaxies close to the Milky Way. The globular cluster 47 Tucanae can be seen with the naked eye as a hazy star very close to the SMC. A large-aperture telescope shows its countless stars packed together in a dense ball.
In the east you can locate Canis Major, which is hard to miss because it is home to the blazing star Sirius. In Canis Major, the open clusters NGC 2362 and M41 make for good small-telescope targets. Also coming into view in the east are Orion and Taurus. It is easy to identify Orion because its brightest stars are blue-white Rigel (Beta Orionis) and red Betelgeuse (Alpha Orionis).
The constellation Eridanus is located above Orion and is one of the largest constellations in the sky. There you will find the interesting multiple star system Omicron-2 Eridani, with three components, and the double star Theta Eridani. Both are visible with small telescopes. Deep-sky observers with dark skies will be able to spot the barred spiral galaxy NGC 1300, located approximately 69 million light-years from Earth, in the same constellation using large telescopes.
The Leonid meteor shower is annually active each November, and this year the Leonids will peak on the night of November 17-18. The shower is called Leonids because its radiant – the point in the sky where the meteors seem to emerge from – lies in the constellation Leo. The Leonids occur when the Earth passes through the debris left by Comet Tempel-Tuttle. The comet takes about 33 years to make one orbit around the sun.
