Today’s Astronomical Events – December 23rd, 2014

Long dark nights provide observers in the northern hemisphere an excellent opportunity to get to know the winter constellations. Follow the three stars of Orion’s belt up to find Aldebaran which marks the red eye of Taurus, the Bull. Follow the three stars down to find Sirius, the brightest star in the sky, in the constellation Canis Major. Betelgeuse, the orange giant star of Orion’s right shoulder, and Rigel, the brilliant blue-white star of his left leg, point the way to Gemini, the Twins. Meanwhile, in the southern hemisphere, poor Orion appears to hang upside down.
