Kiss the Sky Tonight -- Month of November 2021

Posted by Guy Pirro   11/03/2021 12:07AM

Kiss the Sky Tonight -- Month of November 2021

In 1054, Chinese astronomers took notice of a “guest star” that was, for nearly a month, visible in the daytime sky. The “guest star” they observed was actually a supernova explosion, which gave rise to the Crab Nebula, a six-light-year-wide remnant of the violent event. With an apparent magnitude of 8.4 and located 6500 light-years from Earth in the constellation Taurus, the Crab Nebula can be spotted with a small telescope. The nebula was discovered by English astronomer John Bevis in 1731, and later observed by Charles Messier who mistook it for Halley’s Comet. Messier’s observation of the nebula inspired him to create a catalog of celestial objects that might be mistaken for comets. Thus, the Crab Nebula (NGC 1952) took on the designation of Messier 1, or simply M1. This large mosaic of the Crab Nebula was assembled from 24 individual exposures captured by Hubble over three months. The colors in this image do not match exactly what we would see with our eyes but yield insight into the composition of this spectacular stellar corpse. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The blue in the filaments in the outer part of the nebula represents neutral oxygen. Green is singly ionized sulfur, and red indicates doubly ionized oxygen. These elements were expelled during the supernova explosion. A rapidly spinning neutron star (the ultra-dense core of the exploded star) is embedded in the center of the Crab Nebula. Electrons whirling at nearly the speed of light around the star’s magnetic field lines produce the eerie blue light in the interior of the nebula. The neutron star, like a lighthouse, ejects twin beams of radiation that make it appear to pulse 30 times per second as it rotates.

Kiss the Sky Tonight -- Month of November 2021

Welcome to the night sky report for November 2021 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. In November, hunt for the fainter constellations of fall, including Pisces, Aries, and Triangulum. They will guide you to several galaxies and a pair of white stars. Look for spiral galaxy M74 and the Triangulum Galaxy. Enjoy the Moon and planets after sunset all month, plus a lunar eclipse. A partial lunar eclipse will be visible to much of the world on Nov. 18th and 19th.The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.

All month long, if you're up late and cast your gaze toward the east, you'll notice some familiar companions have begun rising late in the night. The familiar stars of Northern winter skies are returning, rising late at night and sitting high in the south by dawn. 

You'll find the Pleiades star cluster leading the constellations Taurus the bull and the hunter Orion, followed by the brightest star in the sky, Sirius – all of them back to keep us company on the long winter nights here in the Northern Hemisphere. (And for those in the Southern Hemisphere, they're keeping you company on shorter nights as spring gives way to summer there.) 

The dark, cold nights of November make for good hunting for the fainter constellations of fall. Pegasus flies high in the southeast after nightfall and is a good guidepost for some of autumn’s dimmer patterns.

Look south and east of the Great Square of Pegasus for Pisces, the fish. In Greek legend, the two fish, tied together with a rope, represent Aphrodite and Eros, who transformed themselves to escape a monster. The sprawling star pattern includes the Circlet, marking the western fish.

Located below the pattern of the eastern fish is the spiral galaxy M74. M74 is known as a grand design spiral and has two prominent bluish spiral arms wound neatly around the redder galactic nucleus. The nucleus appears redder because there is little new star formation there and many of the hot blue stars have evolved to become red giant stars or have exhausted their fuel altogether.

 

 

 

 

NASA’s Spitzer Space Telescope provides a dramatic view of the infrared light of the galaxy. The pink hues depict dust lanes that punctuate the spiral arms, showing dense cloud regions where new stars can form.

To the east of the Great Square and Pisces lies the small pattern of Aries the ram. The third-brightest star in the pattern, named Mesarthim, is a lovely pair of white stars, easy to distinguish in a small telescope.

Above Aries is the constellation of Triangulum. The constellation contains the third-largest galaxy of our Local Group, after the Milky Way and Andromeda galaxies: M33, the Triangulum Galaxy. This galaxy, which is relatively large and diffuse from our perspective, can be spotted with binoculars.

NASA’s space telescopes have imaged M33’s spiral features in great detail. Spitzer’s infrared view shows the distribution of dust in its ragged spiral arms. An ultraviolet image from NASA’s GALEX mission shows emissions from hot stars in its disk. Look for the bright blue and white areas to see where star formation has been extremely active over the past few million years. Patches of yellow and gold are regions where star formation was more active 100 million years ago.

From November 6th through the 11th, watch the Moon glide past Venus, Saturn, and Jupiter after sunset in the south/southwest. In particular, if you step outside for a look on November 7th, you'll find the four-day-old crescent Moon just about 2 degrees away from Venus. Should be really pretty, so don't miss it.

And from now through early December, you'll find Jupiter and Saturn drawing a little closer to Venus each night.

 

 

 

A partial lunar eclipse is on the way, taking place overnight on November 18th and 19th, when the Moon slips into Earth's shadow for a couple of hours. Weather permitting; the eclipse will be visible from any location where the Moon appears above the horizon during the eclipse. Depending on your time zone, it'll occur earlier or later in the evening for you.

Now that's a huge swath of the planet that'll be able to see at least part of the eclipse, including North and South America, Eastern Asia, Australia, and the Pacific Region. So check the timing of its visibility for your area.

For U.S. East Coast observers, the partial eclipse begins a little after 2:00 AM, reaching its maximum at 4:00 in the morning. For observers on the West Coast, that translates to beginning just after 11:00 PM, with a maximum at 1:00 AM.

Partial lunar eclipses might not be quite as spectacular as total lunar eclipses – where the Moon is completely covered in Earth's shadow – but they occur more frequently. 

And that just means more opportunities to witness little changes in our solar system that sometimes occur right before our eyes.

This time of year provides brave chilly nights to enjoy the constellations, stars, and galaxies of the November sky.

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.
