The great show in the winter sky


Look at the sky in these nights. You will see some of the most beautiful constellations with interesting objects as nebulas, star clusters and different types of stars.
Orion is a hunter, the lover of Artemis, goddess of the hunt. In this constellation you can see two of the brightest stars in the sky. Betelgeuse is a red supergiant that marks the hunter's shoulder, while Rigel is a blue supergiant star that marks the knee. Bellatrix, Orion's left shoulder, is a blue giant. Saiph serves as the hunter's right foot. There is a chain of three stars that mark his belt: Alnitak, Alnilam and Mintaka. Below of Alnitak there is a chain of stars and a visible nebula, Orion's nebula: all of them forms the hunter's sword. Other stars form the head and the shield.
Canis major, the greater dog, follows Orion through the sky. This constellation contains Sirius, the brightest star in the night sky and one of the closest stars to Earth, at a distance of 8.6 light-years.
Taurus represents the figure of a celestial bull charging towards Orion. The hed of the bull is the V-shaped star cluster named the Hyades; the brilliant red Aldebaran, an orange giant star, marks its eye. Taurus has one of the best known open clusters, with seven stars easily visible to the naked eye. This is the Pleiades, also named the Seven Sisters. They are the daughters of Atlas and Pleione in Greek mythology.
Try to see these constellations, discover the different stars. Are you able to watch the Pleiades star cluster? How many stars can you see in it? I am willing to read your comments.

  2. Fantastic, Lucia. I hope you enjoy looking at the sky, and so does your mother. It's difficult to see Pleyades star cluster from Granada. Try to discover it! Good luck.
