What's In The Sky - May 2019

Get outside with your telescope on clear May evenings to see celestial treats! With the weather warming up and skies clearing up, there's no shortage of celestial delicacies to view with telescopes and binoculars. Here are a few of Orion Telescopes and Binoculars top suggestions for May observing:

Eta Aquarid Meteor Shower

Grab a blanket or a comfy lounge chair to sit back, relax and watch the Eta Aquarids meteor shower, one of two annual showers caused by dust particles from Halley's Comet. Catch the peak of the dazzling show before dawn on May 6th. The approximate peak rate is 10-30 per hour, but meteors should be visible from April 24th through May 20th. Look for meteors appearing to radiate from the constellation Aquarius.

Four Big Planetary Nebulae

Use a 6" or larger telescope and an Oxygen-III filter to catch nice views of four relatively large planetary nebulae in May skies. See the "Ghost of Jupiter," NGC 3242 in Hydra; M97, "the Owl Nebula" in the Big Dipper; NGC 4361 in Corvus, and the famous "Ring Nebula", M57 in Lyra just a few degrees from the bright star Vega. To help you locate these objects, use the Orion DeepMap 600.

New Moon, Dark Skies

Take advantage of the dark skies provided by the New Moon on May 4th to scope out the many star clusters, galaxies and other deep-sky gems on display. Pack up your astronomy gear using our full line of telescope and accessory cases and head to a dark sky site for the best viewing conditions.

Five Glittering Globulars

Five picture-perfect examples of globular star clusters will be visible in May skies. Check out M3 in the constellation Bootes. M13, the "Great Cluster in Hercules" will be visible near the zenith. M5 can be found in Serpens and M92 in the northern section of Hercules. Be sure to track down M4 (NGC 6121) in Scorpius on May 27th, as it will be in a great position for telescopic study throughout the night, reaching zenith around midnight. Big telescopes will provide the best views, but even a pair of humble 50mm or larger binoculars will show you these dense balls of stars from a dark sky site.

Four Face-On Spirals

Use a large telescope to see the classic pinwheel shapes of galaxies M51 and M101 in the Big Dipper asterism of Ursa Major, and M99 and M100 in the Virgo galaxy cluster. There are also dozens of additional galaxies to explore in the Virgo cluster with a large aperture telescope.

May's Challenge Object

May skies present some of the best opportunities to grab a view of Omega Centauri - the brightest globular star cluster in the sky! While it's big and bright, even visible as a "fuzzy" star in binoculars, the challenge Omega Centauri presents is its low position in southern skies, which can make it unobservable from higher northern latitudes. If you're having trouble locating the famous globular cluster, Bruce McClure from EarthSky.org suggests letting the sparkling blue-white star Spica help you. He explains that when Spica climbs highest up for the night, so does Omega Centauri - look for it 35 degrees directly below Spica.

Messier 63 - The Sunflower Galaxy

As the spring night sky looms overhead, there are a plethora of galaxies and galaxy clusters for targeting with the Astronomical Telescopes for Educational Outreach (ATEO) at Insight Observatory. One such galaxy is Messier 63, the "Sunflower Galaxy" located in the constellation Canes Venatici. One of Insight Observatory's Starbase dataset subscribers, Utkarsh Mishra, processed roughly 10 hours (color) and 6 hours (monochrome) of data integration of the galaxy acquired by ATEO-1, the 16" f/3.7 Astrograph reflector located in New Mexico. Utkarsh's processed image of Messier 63 is one of the best we at Insight Observatory has ever seen. We were very excited to see his final processed color and monochrome images of the galaxy. It is the first time an image from ATEO-1 has been processed with so many integration hours.

Although M63 only has two spiral arms, many appear to be winding around its yellow core. The spiral arms shine with the radiation from recently formed blue stars and can be more clearly seen in infrared observations. By imaging flocculent spiral galaxies like M63, astronomers hope to gain a better understanding of how stars form in such systems.

Messier 63 or M63, also known as NGC 5055 was discovered in 1779 by the French astronomer Pierre Méchain and was the first of 24 objects that Méchain would contribute to Charles Messier’s catalog. The galaxy is located roughly 27 million light-years from Earth. It has an apparent magnitude of 9.3 and appears as a faint patch of light in small telescopes. The best time to observe this galaxy is during the month of May.

In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63. It was discovered May 24, 1971, and reached peak light around May 26. The spectrum of SN 1971 I is consistent with a supernova of type I. However, the spectroscopic behavior appeared anomalous.

5th-Graders Image Spring Deep-Sky Objects

Insight Observatory, once again, had the pleasure this school year of working with Ms. Christine DeSantis and her 5th-grade students at the Plymouth South Elementary School located in Plymouth, Massachusetts. The students used Insight Observatory's Educational Image Request (EIR) form to acquire deep-sky images from the 16" f/3.7 reflector remote robotic imaging telescope (ATEO-1) located in the dark skies of Pie Town, New Mexico.

Ms. DeSantis states; "As part of our science unit on space, our class received the exciting opportunity to receive some images via a remote telescope in New Mexico. Students visited the Insight Observatory website to learn more about the telescope and its location. They were then paired up to choose some deep sky images to have photographed. It was particularly exciting for the students to find out that the spring sky is loaded with galaxies. Students chose from a list of open star clusters, spiral galaxies, globular clusters, and planetary nebula. They were thrilled when their images arrived. After seeing their images, students discussed the immensity of distances in space and the variation in galaxy shapes. This was such a motivating and inspiring project. We are very grateful to have been able to benefit from Insight Observatory’s educational outreach program!"
