This Week’s Sky at a Glance, 2024 Nov 30 – Dec 7
With the Great Square of Pegasus at its peak in the early evening it is a good time to visit the autumn constellations with binoculars. The flying horse soars upside down, and if you regard the two lines of stars in Andromeda as its hind legs it looks like a rocking horse. Well, to me it does. The horse’s neck stretches off the southwest corner of the square, and then it angles off to the snout. Extending a line from the head to the snout by about half that distance brings you to the globular cluster M15, looking like a fat star in binoculars or something snorted from the horse.
The opposite star of the square is Alpheratz at the head of Andromeda. The second star from there, along the brighter line of her body, is Mirach, which looks orange in binoculars. Moving to the star above it in the second line of Andromeda, and beyond to another star, puts you near M31, the Andromeda Galaxy. In a dark sky you can see it as a faint smudge with the naked eye and it is spectacular in binoculars. Going the opposite direction from Mirach, about halfway to the tip of Triangulum and a tad to the left, is M33. This face-on spiral galaxy is much tougher to see; you will need a transparent sky.
This Week in the Solar System
Saturday’s sunrise in Moncton is at 7:40 and sunset will occur at 4:35, giving 8 hours, 55 minutes of daylight (7:42 and 4:43 in Saint John). Next Saturday the Sun will rise at 7:48 and set at 4:33, giving 8 hours, 45 minutes of daylight (7:50 and 4:41 in Saint John). The Moon is new on Sunday and it makes a scenic pairing with Venus on Wednesday.
Brilliant Venus can be seen in the southwest soon after sunset, slowly gaining altitude nightly and setting around 7:45. Saturn is at its highest and best for observing by 6:30 pm, showing its rings nearly edge on. Jupiter is at opposition next Saturday and it will be in the night sky for 15 and-a-half hours this week. Since Jupiter rotates in less than ten hours, the Red Spot will be visible for telescope users at some time every evening. Mars reaches its first stationary point next Saturday, therefore remaining within a binocular view above the Beehive star cluster for a month. Mercury is too close to the Sun for viewing this week, reaching inferior conjunction on Thursday.
