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 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 ...

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 ...

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 ...

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 ...

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 ...
