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, ...

Reflection nebulae reflect the light from nearby stars. The stars that illuminate them aren’t powerful enough to ionize the nebula’s gas, as with emission nebulae, but their light scatters through the ...

The Boomerang Nebula is one of the most puzzling bipolar reflection nebulae known. It lies 5,000 light-years distant in Centaurus, just 3⅓° north-northeast of Gacrux (Gamma [γ] Crucis) in the Southern ...

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 ...

Star Gazers host Trace Dominguez breaks down the 5 different types of nebulae. Star Gazers host Trace Dominguez breaks down the 5 different types of nebulae: emission, reflection, planetary, supernova ...

NASA's Hubble Space Telescope dazzled with a new image showcasing a trio of radiant stars nestled within the luminous expanse of a reflection nebula. The celestial display resembles a dazzling cosmic ...

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 ...

A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely seen ...

The Chandra team has released a striking new composite image of the Cocoon Nebula, a reflection and emission nebula in the ...

Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a ...
