Butterflies of the Milky Way await scrutiny with telescopes small and large.
Despite its dodgy reputation, this planetary nebula is easy to find (for both Northern and Southern Hemisphere observers) if you go about it the right way.
When you leave the planets, moons, and comets of our solar system behind, you enter the realm of the deep sky, a place of subtle glows and faint lights.
Nebulae are among the most beautiful sights in the night sky but their diffuse nature can make them challenging to locate. Here are a few interesting nebulae, and most are easy to spot.
Globular clusters are more concentrated in the direction of Sagittarius since that's where we find the center of the Milky Way. This area of the sky affords us opportunities to see several of these rich, ancient clusters in close proximity.
If you can find bright Antares in Scorpius, you can use our chart to find these half dozen globular star clusters with a telescope and maybe even binoculars.
The sky between the Big and Little Dogs may be poor in bright stars, but it’s rich in star clusters for small telescopes.
Open clusters are popular targets for deep-sky observers, particularly when composed of varied-color stars. Here are some treats for scopes both large and small.
You don't need a big telescope to be dazzled by deep-sky wonders, particularly if your target is one of the many lovely star clusters.
Amateur skygazers can spend hours roaming ghostly clouds of interstellar dust. You just need to know where to look.
On a long-awaited tour of the southern Milky Way, Alan Whitman discovers many splendid sights in far-southern skies.
Here's how to hone your galaxy-hunting skills — and what to expect at the eyepiece.
This famous recurrent nova has just erupted for the first time in 21 years, reaching magnitude 4.8 on February 13th.
This recurrent nova last went off in 1985. It could do so again almost any night. By catching this nova on the rise, you’ll help professional astronomers turn their “big guns” on it.
