Fittingly named for its shape, the Dark Wolf Nebula is no mere puppy — it spans an area some fourContinue reading "ESO captures Dark Wolf Nebula stalking across the Milky Way "

Orion? The Orion Nebula! Andromeda? The Andromeda Galaxy, of course! Lyra? Easy — the Ring Nebula. And Perseus?Continue reading "Five ‘shy,’ lesser-known deep-sky gems to observe"

That’s because you’re viewing objects that are too faint to trigger your eyes’ color receptors. This is the sameContinue reading "Will my telescope show color when viewing deep-sky objects?"

The increased light sensitivity of the emulsion coatings on dry plates allowed for shorter exposure times and produced sharper images of the night sky. In 1881, the French inventors brothersContinue reading "How we found Morehouse’s Black Ring: A dark nebula hiding in plain sight"

Its name comes from French astronomer Nicolas Louis de Lacaille, who surveyed the southern sky from 1750 to 1753 at the Cape of Good Hope. He called the pattern “The Sculptor’s Workshop,”Continue reading "Observe the galaxies of Sculptor"

When I was a teenager, many moons ago, I bought my first telescope, a Celestron 8. I remember excitedly unboxing it the day it arrived. Fortunately, I had a clear sky that evening and stayed up all night observing. In the early morning, IContinue reading "Deep-sky objects to target as a novice observer"

You’ll first notice a pair of bright stars that give this deep-sky object the appearance of a common bird. Indeed, Astronomy magazine Editor Dave Eicher christened it the Owl Cluster more than 40 years ago.Continue reading "Observe a great star cluster: This Week in Astronomy with Dave Eicher"

The immensity of our universe never fails to fascinate curious minds. But when it comes to truly grasping it — let alone explaining it — words and numbers often fall short.

Globulars get their name for their distinct, globe-like appearance — a ball of stars that increases in density and brightness as you look closer to the core. Unlike open clusters, which are collections of stars that form from theContinue reading "Explore the Hercules Cluster: This Week in Astronomy with Dave Eicher"
