Kiss the Sky Tonight -- Month of December 2018

Kiss the Sky Tonight -- Month of December 2018

 

Few star clusters are seen to be so close to each other. Some 7000 light-years away, this pair of open star clusters is an easy binocular target, a lovely star field in the constellation Perseus. Visible to the unaided eye from dark sky areas, it was cataloged in 130 BC by Greek astronomer Hipparchus. Now known as NGC 869 (above right) and NGC 884, the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun. In addition to being physically close together, the clusters' ages based on their individual stars are similar -- evidence that both clusters were likely a product of the same star-forming region.

Kiss the Sky Tonight -- Month of December 2018

Welcome to the night sky report for December 2018 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. Saturn’s iconic rings are clearly visible with backyard telescopes in early December. Mercury and Venus appear later in the month. Also look for Eta Cassiopeiae, a double star, with binoculars or a small telescope to discern its gold and blue hues. Finally, don’t miss the mid-December Geminid meteor shower. You could see as many as 60 colorful meteors per hour. The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.

Look for Saturn low in the southwestern sky at dusk, early in the month. Its iconic rings are clearly visible with backyard telescopes in early December. But by the middle of the month, the planet slips into the glare of the Sun.

Mars glints red in the southwestern sky against the stars of Sagittarius. Modest telescopes readily reveal its ocher disk. As the Earth-Mars distance increases throughout the month, it grows steadily smaller and dimmer in the sky.

Two prominent constellations in the December night sky represent notable individuals of ancient Greek mythology. The great hero Perseus holds the head of Medusa the Gorgon. Located in Perseus is M34, an open star cluster about 1,400 light-years away from us. Open star clusters are groups of young stars that all formed at the same time within a large cloud of dust and gas. Look for it with the naked eye or with binoculars in a dark sky.

Queen Cassiopeia was punished for her conceit and vanity by being tied to her throne. Cassiopeia’s “W” shape makes this constellation easy to identify. Eta Cassiopeiae is a wonderful and colorful double star. Use binoculars or a small telescope to discern its gold and blue hues. M103 in Cassiopeia is a fine open star cluster with a prominent red star near the center. Its fan shape is evident in binoculars.

Lying between Cassiopeia and Perseus is the lovely Double Cluster, NGC 869 and NGC 884. This pair of open star clusters is easy to see with binoculars. The Double Cluster resembles a handful of diamonds scattered on black velvet, with a ruby in between.

 

 

 

 

 

 

 

Look for Venus blazing in the eastern sky before the chilly December sunrise.

In the middle of the month, diminutive Mercury joins Venus in the morning sky, popping briefly above the eastern horizon before the Sun. A modest telescope will show both disks in their moon-like phases, as we see only part of their sunlit sides.

The mid-December night sky hosts the lovely Geminid meteor shower. The shower peaks on the night of December 13 to 14. Under a dark sky, you could see as many as 60 colorful meteors per hour.

 

 

 

 

 

 

 

The night sky is always a celestial showcase. Explore its wonders from your own backyard.

The following Deep Sky Objects are found in constellations that peak during the month. Some can be viewed with a small telescope, but the majority will require a moderate to large telescope. The following is adapted from my personal viewing list: "The Guy Pirro 777 Best and Brightest Deep Sky Objects."
