NASA’s Hubble Space Telescope captured variable stars and circumstellar disks in NGC 1333, showing protostars, Orion variable stars, and reflection nebulae in the Perseus Molecular Cloud.

A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new ...

The article details various types of deep-sky objects observable by amateur astronomers, including double stars, variable stars, open and globular star clusters, emission, planetary, and reflection ...

This Hubble Space Telescope image captures a portion of the reflection nebula IC 2631, which contains a protostar, the hot, dense core of a forming star that is accumulating gas and dust. Eventually, ...

The Trifid Nebula (M20) is the trifecta of deep-sky objects: It combines a blue reflection nebula with an emission nebula glowing in red Hydrogen-alpha (Hα) light, all divvied up by opaque lanes of ...

Many scientific terms are very specific, but the term nebula is, well, nebulous. In a very generic sense, it simply means a fuzzy thing. But there are a wide variety of astronomical objects that can ...

Stars form within dark molecular clouds of gas and dust called nebulae, but it's rare to capture these stellar nurseries clearly. A dramatic new image from the Dark Energy Camera (DECam) in Chile ...

Emission nebulae are the subject of many of the most spectacular astrophotographs published in the last decade. Although there are many subcategories of nebulae, they all consist of interstellar gas ...
