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 ...

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 ...

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 ...

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 ...

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 ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. It’s one of the most common words used by astronomers—and ...

Hubble has captured a mesmerizing photo of a cosmic nursery found in Orion. The reflection nebula, which is known as NGC 1999, looks eerily similar to a keyhole. The nebula itself, the European Space ...

The glowing nebula IC 2220, nicknamed the Toby Jug Nebula owing to its resemblance to an old English drinking vessel, is a rare astronomical find. This reflection nebula, located about 1200 ...
