What appears to be a densely populated star field with a few galaxies visible.

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?

The spectacular Large Magellanic Cloud

The Large Magellanic Cloud, which is visible to the unaided human eye, might look like a small, faint bit of the Milky Way that’s broken off. But really it’s a separate small galaxy, thought to be orbiting our larger Milky Way.

Messier 33: 2nd-closest spiral galaxy

The Triangulum galaxy, aka Messier 33, is 2.7 million light-years away, and the 3rd-largest member of our Local Group, after the Milky Way and Andromeda galaxies.

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. How to find it in your sky.

Meet M13, the Great Cluster in Hercules

Many stargazers call it the finest globular cluster in the northern half of the heavens. It’s M13, also known as the Great Cluster in Hercules.

Small Magellanic Cloud orbits Milky Way

You need to be in Earth’s Southern Hemisphere to see the Small Magellanic Cloud. It looks like a luminous cloud, but it’s really a dwarf galaxy, orbiting our Milky Way.

Meet the Double Cluster in Perseus

The Double Cluster in the constellation Perseus is a breathtaking pair of star clusters, each containing supergiant suns. How to find it in your sky.

Awesome beauty of the Eagle Nebula

The Eagle Nebula – aka Messier 16 or M16 – is home to several famous structures, including the Pillars of Creation and the Stellar Spire.

M6 and M7 in the Scorpion’s Tail

If you have a dark sky, look for them. They may well be the finest star clusters visible at this time of year.

Giant star cluster Omega Centauri

All globular star clusters are impressive, but Omega Centauri’s in a class by itself. Sparkling with 10 million stars, it’s the Milky Way’s largest globular.
