Five Glittering Globulars
Five picture-perfect examples of globular star clusters will be visible in May skies. Check out M3 in the constellation Boötes. 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.
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.
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.
