Kiss the Sky Tonight -- Month of October 2019

Posted by Guy Pirro   09/29/2019 04:40PM

Kiss the Sky Tonight -- Month of October 2019

 

The Andromeda Galaxy, also known as M31 or NGC224, is probably the best known galaxy in the sky. Due to its close proximity to Earth, it is also one of the best studied ones. The diffuse light from Andromeda is caused by the hundreds of billions of stars that it contains. In this image, the thousands of distinct stars that appear to surround the Andromeda Galaxy are actually stars in our own galaxy that are well in front of the much larger background object. The Andromeda Galaxy received its name from the mythological princess Andromeda and can be seen on a dark night sky with the naked eye. It is the largest galaxy in the Local Group, which also contains our Milky Way Galaxy, the Triangulum Galaxy, and more than 50 smaller galaxies.

Kiss the Sky Tonight -- Month of October 2019

Welcome to the night sky report for October 2019 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. Crisp, clear October nights are full of celestial showpieces. Find Pegasus, the flying horse of Greek myth, to pinpoint dense globular star clusters and galaxies, including our neighbor, the Andromeda Galaxy (M31, NGC224). Watch for views of M15 (NGC7078) and NGC7331. The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.

 

The crisp, clear nights of October are full of celestial showpieces for the backyard sky gazer.

 

Face southeast after dark to find Pegasus, the flying horse of Greek myth, soaring high into the sky. The prominent square of stars that forms the body makes Pegasus a good guidepost for the autumn sky.

 

Along the western side of the Great Square of Pegasus lies the star 51 Pegasi. It is notable as the first Sun-like star discovered to harbor an orbiting planet

 

 Farther west, near the star Enif, which marks the horse’s nose, lies an entire city of stars -- the globular star cluster M15. Backyard telescopes show a grainy, concentrated sphere of light. NASA’s Hubble Space Telescope shows a stunning globe of ancient stars with many red giants. M15 is one of the densest globular star clusters known in the Milky Way galaxy.

 

Near the Great Square resides an even larger star city -- the galaxy NGC7331. In a telescope, the nearly edge-on spiral galaxy appears as an elongated smudge of faint light. The Hubble view shows that NGC7331 is a galaxy very similar in size and structure to our own. NASA’s Spitzer Space Telescope’s view of the galaxy, which highlights infrared light, reveals a ring of dust circling the galaxy’s center at a radius of nearly 20,000 light-years. Spitzer measurements suggest that the ring contains enough gas to produce four billion stars like the Sun.

 

 

 

 

 

 

 

The brightest star of the Pegasus Great Square, named Alpheratz, marks the head of the princess Andromeda. Beside the Andromeda constellation is M31 (NGC224), the Andromeda Galaxy. Visible in dark skies as an elongated patch of light, the galaxy, at 2.5 million light-years distant, is the farthest object that can be seen with the unaided eye. Binoculars and small telescopes clearly show its nearly edge-on shape. NASA’s GALEX mission imaged the ultraviolet light from the Andromeda Galaxy. The image shows its core and spiral arms traced by hot, massive, young blue stars and dark dust lanes. Andromeda is the nearest large galaxy to our own. Studies indicate that Andromeda is approaching and will collide and merge with the Milky Way more than four billion years from now.

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."
