In a dark sky, look for fuzzy object near bright Antares in the constellation Scorpius. This is M4, one of the closest globular star clusters to our solar system.
Clusters Nebulae Galaxies
They may well be the finest star clusters visible at this time of year, and they’re easy to spot near the Scorpion’s Tail, if you have a dark sky.
Sure, M13, the Great Hercules cluster is wonderful. But some amateur astronomers say this cluster, M5, is even better.
Omega Centauri is the largest globular cluster known in the Milky Way galaxy. You can spot it soon after sunset on these June evenings.
The Great Cluster in the constellation Hercules – also known as M13 – is considered to be the finest globular cluster in the northern half of the heavens.
The Coma Cluster is one of the richest galaxy clusters known. How many suns and how many worlds might be located in this direction of space?
On some moonless night, look for the Orion Nebula below Orion’s Belt. Your eye sees it as a tiny, hazy spot. But it’s a vast region of star formation.
From tropical latitudes in the Northern Hemisphere, where it can be observed, the LMC is best seen in the evening from December to April. From the Southern Hemisphere, it’s easy to see and spectacular!
The Double Cluster is in the constellation Perseus is highest in the northern sky on late autumn and early winter evenings.
Frosty November is often called the month of the Pleiades, because it’s at this time that the Pleiades shine from dusk until dawn.
At a distance of 2.3 million light-years, the Andromeda galaxy (Messier 31) is the closest spiral galaxy to our Milky Way. It’s the most distant thing you can see with your eye alone.
If you could view it with your eye alone – in the sky visible from Earth’s Southern Hemisphere – you would say it does resemble a luminous cloud. Really, though, it is a nearby dwarf galaxy, orbiting our Milky Way.
The Wild Duck Cluster (Messier 11) is found in the constellation Scutum the Shield, just south of the Eagle’s Tail in the constellation Aquila. Unless you have eagle eyes, don’t expect to see this distant star cluster with the eye alone. Starting from the star Altair, star-hop to M11′s general location. Then find it with binoculars!
The Trifid Nebula (Messier 20) is one of the many binocular treasures in the summer Milky Way. Its name means “divided into three lobes,” but you’ll probably need a telescope to see why. On a dark, moonless night, you can star-hop upward from the spout of the Teapot in Sagittarius to the Lagoon Nebula (Messier 8). In the same binocular field, look for the smaller and fainter Trifid Nebula as a fuzzy patch above the Lagoon.
The Lagoon Nebula is the largest and brightest of a number of nebulosities in and around Sagittarius.
Although long-exposure photographs show the Triangulum galaxy (Messier 33) in a beautiful pinwheel shape, this face-on spiral galaxy looks relatively lackluster in binoculars or even the telescope. The Triangulum galaxy has a low surface brightness that makes this faint object a major challenge, with or without binoculars.
Barely visible to the unaided eye on a dark, moonless night, the Eagle Nebula (Messier 16) and Omega Nebula (Messier 17) are best seen through binoculars, or low power in a telescope. These two closely-knit patches of light readily fit within the same binocular field. Star-hop to them from the Teapot in Sagittarius.
Outside on a dark summer night, looking edgewise into our galaxy’s disk, you’ll notice a long, dark lane dividing the bright starry band of the Milky Way. This is the Great Rift.
Between the star Regulus in Leo and the stars Castor and Pollux in Gemini, you might notice a smudge – really a cluster of stars – called the Beehive.
If you’ve never found a deep-sky object on your own before, M4 is a grand place to start. The M4 star cluster is easy to find, because it’s right next to Antares, the brightest star in the constellation Scorpius the Scorpion. This is not an open star cluster or loose collection of fairly young stars. Instead, it’s a globular star cluster, a symmetrical grouping of some of the galaxy’s oldest stars.
