After a massive star dies, the energy ejected from the colossal explosion forms what is known as a nebula — a ginormous, colorful interstellar cloud of gas and dust. Two new images captured by ...

This image taken with the NASA/ESA Hubble Space Telescope showcases the emission nebula NGC 2313. Emission nebulae are bright, diffuse clouds of ionized gas that emit their own light. ESA/Hubble, R.

Located about 7,500 light-years from Earth in the brightest part of the Heart Nebula, is the brilliant NGC 896 Emission Nebula in constellation Cassiopeia. Skywatching enthusiasts Bob and Janice Fera ...

Colorful and wispy Sharpless 2-296 forms the “wings” of an area of the sky known as the Seagull Nebula — named for its resemblance to a gull in flight. This celestial bird contains a fascinating mix ...

The trickiest part of sketching large, complex nebulosity within a star field is accurate positioning of both the stars and the nebula’s structure. Begin by plotting the brightest stars in your sketch ...

Another piece of the jigsaw in understanding how neutron stars work has been put in place following the discovery by scientists of the origin of the high energy emission from rotation-powered pulsars.

A massive cloud of dust and glowing gases speckled with newborn stars in the shape of a seagull shines in a stunning image captured by a telescope in Chile. A new photo from the European Southern ...

Astronomers have discovered an unusual laser emission that suggests the presence of a double star system hidden at the heart of the 'spectacular' Ant Nebula. The extremely rare phenomenon is connected ...

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 ...

The Gum Nebula is a huge cloud of gas, much larger than the Orion Nebula. It's so faint that it wasn't noticed until 1955. Scientists think it might be the remains of an exploded star (supernova).
