Winter Stargazing
Orion the Hunter
Orion is probably the best known of all the constellations. This pattern of stars can be seen in southern half of the evening sky from around Christmas-time through to April.
Look for a bright rectangle of stars with three stars crossing the middle. The big rectangle marks Orion’s body, and the three stars are his famous belt.
The top left star is called Betelgeuse, it is an old red star which will explode at the end of its life. This is expected to happen within the next 100,000 years. It probably won’t happen in our lifetimes, but it’s always fun to imagine witnessing this event! When it explodes, it will become so bright that it will be visible in the daytime.
Under Orion’s belt, you might see a fuzzy blob. This is the Orion Nebula, a vast cloud of gas and dust within which new stars are being born.
King of the planets
Look high above Orion and to the left. Can you see a very bright dot? This is the giant planet Jupiter. It looks just like a star, but it is reflecting sunlight rather than shining by itself.
If you have a good pair of binoculars (ones with wide ends are best), you might be able to spot one or more of Jupiter’s largest moons close to the planet. If you can spot them, draw where they are then look again another day to see how they move.
