Kiss the Sky Tonight -- Month of January 2018
Posted by Guy Pirro on 1/2/2018 12:01 PM


M45 - The Pleiades Star Cluster. Perhaps the most famous star cluster on the sky, the Pleiades can be seen without binoculars from even the depths of a light-polluted city. Also known as "The Seven Sisters" and M45, the Pleiades is one of the brightest and closest open clusters. The Pleiades contains over 3000 stars, is about 400 light years away, and only 13 light years across. Quite evident in the above photograph are the blue reflection nebulae that surround the brighter cluster stars. Low mass, faint, brown dwarfs have also been found in the Pleiades.

Happy New Year and welcome to the night sky report for January 2018 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard and follow the advice of James Marshall Hendrix (apparently a fellow admirer of the heavens): "Excuse me while I kiss the sky."

The winter sky is filled with brilliant stars. An ancient constellation, Auriga was pictured as a goat herder by the Greeks and Romans. Auriga is a beautiful circlet of jeweled stars, gracing the sky overhead.

Capella, the sixth-brightest star in the sky, is a double star. The two stars are yellow stars like our own Sun, but they are about 10 times larger and 50 and 80 times brighter.

Near Auriga is the large constellation Taurus, the Bull. In Greek legend, this group of stars represented Zeus in the disguise of a white bull with golden horns. His eye is the orange Aldebaran, a red-giant star nearing the end of its life.

The Bull's V-shaped head is created by Caldwell 41 - The Hyades, a beautiful cluster of stars, easily seen with the naked eye.

M45 - The Pleiades star cluster lies near the head of the Bull. Large and bright, this star cluster is the best known in the sky and is often called "The Seven Sisters." The unaided eye can see just six or seven stars, but the Pleiades cluster contains over 250. Binoculars showcase the cluster at its best. The stars in this stellar swarm are hot and young. They are passing through a dusty cloud that reflects their blue light.

Saturn and Mercury rise together every morning before sunrise. Over the course of the month, the two planets shift position in the predawn sky. They appear to converge in the middle of the month, and then slowly swap places. With a backyard telescope, the two are easy to distinguish.

Bright Jupiter and reddish Mars rise together a few hours before the Sun. On the morning of January 6th, they appear less than half a degree apart, and can be seen in the same field of view in a backyard telescope.







The Quadrantid meteor shower peaks on the night spanning January 3rd and 4th. Skywatchers who brave the cold might spot up to 40 meteors per hour.







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."
