Kiss the Sky Tonight -- Month of October 2018

Posted by Guy Pirro   10/09/2018 04:41PM

Kiss the Sky Tonight -- Month of October 2018

The Heart and Soul Nebulas are two bright emission nebulas that can be found in Cassiopeia. The Heart Nebula (IC 1805), on the right, has a shape reminiscent of a classical heart symbol. The Soul Nebula (IC 1848) is on the left. Both nebulas shine brightly in the red light of energized hydrogen. Several young open clusters of stars populate the image and are visible in blue, including the nebula centers. Light takes about 6000 years to reach us from these nebulas, which together span roughly 300 light years. Studies of stars and clusters like those found in the Heart and Soul Nebulas have focused on how massive stars form and how they affect their environment.

Kiss the Sky Tonight -- Month of October 2018

Welcome to the night sky report for October 2018 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. Look for Pegasus, the great winged horse of Greek mythology, prancing across the autumn night sky. Binoculars and small telescopes will reveal the glowing nucleus and spiral arms of our neighbor, the Andromeda Galaxy. Don’t miss the Orionid meteor shower, which peaks on the night of October 21 to 22.The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.

Planets begin to depart the evening sky as chilly October winds blow.

Mars and Saturn still dominate the southern sky, Mars in Capricornus and Saturn in Sagittarius. A modest telescope reveals the rings orbiting Saturn.

The waxing moon travels between the two in the middle of the month.

The orange disk of Mars decreases in size and its features fade from view as its distance from Earth increases over the course of the month.

Pegasus, the great winged horse of Greek mythology, prances across the autumn night sky. His body is denoted by a large area of stars known as the “Great Square.” Pegasus hosts 51-Pegasi, the first Sun-like star known to have an extra-solar planet.

The brightest corner of the Great Square, Alpheratz, is also the brightest star in the constellation Andromeda. In Greek mythology, this princess was chained to a rock near the sea to appease a sea monster. Within Andromeda’s boundaries, look for M31, the Andromeda Galaxy, an island of billions of stars. On a clear, dark night it appears as a faint smudge of light. Approximately 2.5 million light-years away, M31 is the closest spiral galaxy to our own Milky Way Galaxy and the most distant object you can see with your eyes alone. Binoculars and small telescopes reveal M31’s glowing nucleus and spiral arms. A smaller companion galaxy, M110, appears as a faint spot near the large galaxy. The Andromeda Galaxy is slowly pulling in, and will eventually consume, another one of its small companion galaxies, M32.

 

 

 

The Orionid meteor shower peaks on the night of October 21 to 22. However, the bright light of the nearly full moon may wash out all but the brightest meteors. After midnight, look to the east where the constellation Orion is rising. Every few minutes you may spy a tiny remnant of Halley’s Comet burning up high in the atmosphere.

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."
