Christmas Conjunction

  How about a celestial light show to round out your Christmas holiday? Take a look east after sunset and you'll see one.

  The moon and Jupiter will be in conjunction on the night of the 25th, and will only be separated by 2 degrees. Directly above Jupiter will be M45 (the Pleiades), and below and to the right of the moon will be the red giant Aldebaran. Together these celestial objects will be a stunning sight.


    Did you get a new scope for Christmas? This is an excellent opportunity to try out your new scope! The moon and Jupiter are easy and fascinating objects to observe. The moon will be nearly full, so you may find it a bit too bright in the eyepiece. Try stopping down the aperture or using a neutral density moon filter if your scope came with one. Jupiter will be a sight to behold. The four Galilean moons: Io, Europa, Ganymede and Callisto will be visible, and the great red spot will be near Jupiter's meridian at around 9:30pm PST, or 6:30 EST.
