The Owl Nebula is an example of a planetary nebula — a type of object that yields glimpses of stellar death in slow motion.

Globular cluster M15 hides within it a planetary nebula, Pease 1. Observers with large scopes and steady skies can find it.

The smoking gun of the creation of lithium in explosions on white dwarf stars may have been found, in a spike of gamma rays ...

Such changes would make it difficult for life as we know it to survive on Earth. The increased heat and radiation would ...

Using a new imaging technique, the researchers successfully captured more than one thousand colors that identified specific celestial objects like 500 planetary nebulae, which are responsible for the ...

Galaxies shine in a rainbow of emissions from gas, dust, and stars. Each of these building blocks emits light at specific ...

This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 - 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

Sculptor—officially labeled NGC 253—is considered a starburst galaxy, one heavy with stellar action. It's located 11 million light-years away in the Southern Hemisphere's constellation Sculptor, and ...

The galactic masterpiece combines over 100 exposures to reveal previously unseen features of stars in formation.

The researchers observed the Sculptor Galaxy for over 50 hours with the Multi Unit Spectroscopic Explorer (MUSE) instrument on the VLT to create the detailed map. They then stitched together over 100 ...

New discoveries: Planetary nebulae and star formation The detailed image has already led to the discovery of 500 new planetary nebulae—shells of gas and dust emitted by dying stars.
