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

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.

The discovery is the first direct observational confirmation of a theory for how young stars feed on, and then explosively ...

As we continue to break new ground in the field of cosmology, the importance of carefully categorizing the objects we see comes into focus. Part of this stems from the fact that, increasingly, we find ...

The reflection nebular NGC 1999 lies about 1,350 light years from Earth in the constellation Orion, and exhibits an inky black central “keyhole” in this image taken by the Hubble Space Telescope ...

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 ...

The Hubble Space Telescope searches the universe to understand how planets, stars, and galaxies form. Recently, it captured this image of a nebula known as GN 04.32.8 within a larger stellar nursery ...

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 ...

UBVRI data are presented for three stars in reflection nebulae near the Herbig-Haro objects recently discovered in the Gum nebula. The likely distance to all three stars as well as the Herbig-Haro ...
