The magnificent constellation Canis Major, the Big Dog, is at its highest in the south on February evenings. It is host to Sirius, the brightest star in the night sky.

The Moon visits Mars and Saturn in the predawn sky this week. This is an exciting time to view both planets. Mars is brightening rapidly, and Saturn’s rings are on great display.
This is a great time to view Jupiter, the king of the planets. It’s well up in the east by the time the sky grows dark, and very high by late evening.
Orion floats high in the south on January evenings. Its seven main stars form a pattern that has been likened to a giant man or woman all around the world.
