Kiss the Sky Tonight -- Month of May 2021

The elliptical galaxy M87 is the home of several trillion stars, a supermassive black hole, and a family of roughly 15,000 globular star clusters. For comparison, our Milky Way galaxy contains only a few hundred billion stars and about 150 globular clusters. The monstrous M87 is the dominant member of the neighboring Virgo cluster of galaxies, which contains some 2000 galaxies. Discovered in 1781 by Charles Messier, this galaxy is located 54 million light-years away from Earth in the constellation Virgo. It has an apparent magnitude of 9.6 and can be observed using a small telescope most easily in May. This Hubble image of M87 is a composite of individual observations in visible and infrared light. Its most striking features are the blue jet near the center and the myriad of star-like globular clusters scattered throughout the image. The jet is a black-hole-powered stream of material that is being ejected from M87’s core. As gaseous material from the center of the galaxy accretes onto the black hole, the energy released produces a stream of subatomic particles that are accelerated to velocities near the speed of light. At the center of the Virgo cluster, M87 may have accumulated some of its many globular clusters by gravitationally pulling them from nearby dwarf galaxies that seem to be devoid of such clusters today.

Kiss the Sky Tonight -- Month of May 2021

Welcome to the night sky report for May 2021 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. In May, we are looking away from the crowded, dusty plane of our own galaxy, toward a region where the sky is brimming with distant galaxies. Locate Virgo to find a concentration of roughly 2000 galaxies and search for Coma Berenices to identify many more. Key deep sky objects this month are galaxies like M104 (the Sombrero Galaxy), M87, and M64 (the Black Eye Galaxy). At the beginning of the month, the bright planet Saturn will appear to the left of the half-lit Moon and the Moon will form a large triangle with the bright planets Saturn and Jupiter. Around the middle of May you will have an opportunity to see all three of the rocky inner planets (Mercury, Venus, and Mars) at the same time. At the end of the month, look for a total lunar eclipse.

Pleasant spring evenings are ideal for tracing the legendary patterns of the night sky. Find the pattern of the Big Dipper—part of Ursa Major, the Great Bear. Trace past the curve of the Big Dipper’s handle, down through the bright orange star Arcturus, and continue until you come to another bright star: Spica.

Spica is actually a pair of massive blue-white stars. Spica anchors the constellation Virgo, which dominates the southern sky in May. Facing Virgo, we are looking away from the crowded, dusty plane of our own galaxy. In this direction, we have a less obstructed view of the deeper universe, which is brimming with other galaxies.

One of these is a lenticular, or lens-shaped, galaxy known as the Sombrero Galaxy. NASA’s Hubble Space Telescope provides a detailed view of the dark lanes of dust ringing the Sombrero Galaxy’s bright core.

Just above the Y-shape in Virgo is a concentration of roughly 2000 galaxies known as the Virgo Cluster. One of the largest of these is M87, a giant elliptical galaxy with trillions of stars and a supermassive black hole in its core.

The black hole is emitting a jet of material. An image from a ground-based radio observatory shows that the jet shines very brightly in radio light. The radio image also shows a turbulent cloud: evidence for a second jet, firing in the opposite direction.

Next to Virgo lies the constellation Coma Berenices—Bernice’s hair. Tangled in Bernice’s locks are many other distant galaxies—among them the spiral galaxy M64. M64 is also known as the Black Eye Galaxy for the dark area in its disk. Hubble shows that the dark region is a large band of dust spinning in the opposite direction of the inner regions, likely as a result of a collision in the galaxy’s past.

Back toward the handle of the Big Dipper sits the small pattern of Canes Venatici, the hunting dogs. Within the boundaries of this constellation, just below the end star of the Dipper’s handle, telescopes find another faint swirl of light: M51. Hubble shows M51 as a spectacular face-on spiral—the Whirlpool Galaxy—along with a companion galaxy. An X-ray image of the companion reveals shock waves caused by outbursts from a supermassive black hole.

 

 

 

Beginning mid-May, if you can find a clear view toward the western horizon, you'll have an opportunity to see all three of the rocky, inner planets of our solar system at the same time. Starting around May 14th, cast your gaze to the west about half an hour after sunset, local time to see if you can spot Mercury, Venus, and Mars.

To see near the horizon, you need an unobstructed view – free of nearby trees and buildings. Some of the best places for this are the shores of lakes or the beach, open plains, or high up on a mountain or tall building.

In addition to the planets, from around May 14th through May 17th, the crescent Moon joins the party for a lovely planetary tableau. Now, Venus will be really low in the sky. (It'll be easier to observe on its own later in the summer.) But for now, take advantage of this opportunity to observe all of the inner planets in a single view.

May 26 brings a total lunar eclipse. Over several hours, the Moon will pass through Earth's shadow, causing it to darken and usually become reddish in color. The red color comes from sunlight filtering through Earth's atmosphere – a ring of light created by all the sunrises and sunsets happening around our planet at that time.

Because of the reddish color, a lunar eclipse is often called a "blood moon." Just how red it will look is hard to predict, but dust in the atmosphere can have an effect. (And keep in mind there have been a couple of prominent volcanic eruptions recently.)

Lunar eclipses take place when the Moon is full, and this full Moon happens when the Moon is also near its closest point to Earth in its orbit, often called a "supermoon."

 

 

 

Unlike solar eclipses, which you should never look at, it's safe to view lunar eclipses with your eyes. And unlike solar eclipses, which tend to have a narrower viewing path, lunar eclipses are at least partly visible anywhere on the planet's night side. The best viewing for this eclipse will be in the Pacific Rim – that's the western parts of the Americas, Australia and New Zealand, and Eastern Asia. For the US, the best viewing will be in Hawaii, Alaska, and the western states.

For the Eastern U.S., the eclipse begins for you during dawn twilight. You may be able to observe the first part of the eclipse as the Moon just starts to darken, but the Moon will be near or on the horizon as Earth's shadow begins to cover it. The farther west you are, the more of the eclipse you'll be able to see before the Moon sets that morning. Those in the western half of the country will be able to see almost the entire eclipse.

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."
