M13: Great Cluster in Hercules

Stargazers agree that the Great Cluster in the constellation Hercules – also known as M13 – is the finest globular cluster in the northern half of the heavens.

The Coma Cluster of galaxies

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?

Crab Nebula

Look for the Crab Nebula

The Crab Nebula, about 6,500 light years from Earth, is the scattered fragments of a supernova, or exploding star, observed by earthly skywatchers in the year 1054.

Beehive: 1,000 stars in Cancer

On a dark night, look for it as a smudge of light, with three times the moon’s diameter. It’s really a wondrous cluster of stars called the Beehive, or M44.

Orion Nebula: Where stars are born

To find the Orion Nebula in your night sky, look below Orion’s Belt. Your eye sees it as a tiny, hazy spot. But it’s a vast region of star formation.

The spectacular Large Magellanic Cloud

From tropical or Southern Hemisphere latitudes, the Large Magellanic Cloud is easy to see. Look for it in the evening from December to April.

Messier 33 is the 2nd-closest spiral galaxy

Triangulum galaxy, aka Messier 33. is 2.7 million light-years away, and the third-largest member of our Local Group, after the Milky Way and Andromeda galaxies.

Pleiades star cluster, aka Seven Sisters

November is often called the month of the Pleiades, because it’s when this star cluster – sometimes called the Seven Sisters – shines from dusk until dawn.

Small Magellanic Cloud orbits our galaxy

Small Magellanic Cloud resembles a luminous cloud, but it’s really a dwarf galaxy, orbiting our Milky Way. Here’s how to see it, from Earth’s Southern Hemisphere.

Double Cluster in Perseus: 2 star clusters

Charles Messier didn’t include the Double Cluster in his famous catalog. That’s probably because there’s nothing like this magnificent cluster anywhere in the sky.

All about the Andromeda galaxy

At 2.3 million light-years, the Andromeda galaxy is the closest spiral galaxy to our Milky Way and the most distant thing you can see with your eye alone.

The awesome beauty of the Eagle Nebula

Here is the famous Pillars of Creation photo taken by the Hubble Space Telescope. It’s one of the features within the Eagle Nebula.

In a dark sky, look for a fuzzy object near bright Antares in the constellation Scorpius. It’s M4, one of the closest globular star clusters.

M6 and M7: Deep-sky gems in Tail of Scorpius

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.

M5, your new favorite globular cluster

Sure, M13, the Great Hercules cluster is wonderful. But some amateur astronomers say this cluster, M5, is even better.

Messier 8 is the Lagoon Nebula

The Lagoon Nebula aka M8 is the largest and brightest of a number of nebulosities in and around Sagittarius.

M17 is the Omega Nebula

Barely visible to the unaided eye on a dark, moonless night, the Omega Nebula (Messier 17) is best seen through binoculars, or low power in a telescope.

The Trifid Nebula, or M20

The Trifid is a famous summertime binocular object. Its name means “divided into three lobes.” If you view this nebula through a telescope, you’ll see why.

Exploring the Trifid Nebula

It’s a stellar nursery, a cluster of young stars, a bright red emission nebula, a lovely blue reflection nebula, and an interesting dark nebula divided into three …
