We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

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 ...

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

How stars die: White dwarfs, neutron stars and supernovae The lives and deaths of stars shape the universe—from the gentle fading of white dwarfs to the explosive furnaces that forged the elements of ...

Using the James Webb Space Telescope, scientists found a dusty disk surrounding the dying white dwarf creating the famous Ring Nebula.

The Eskimo Nebula (Image: NASA)) The youngest known planetary nebula, formed by a star rapidly evolving into a white dwarf, expelling gas and dust into space.

The white dwarf was once a star several times more massive than the Sun. As it aged, it expelled its outer layers in a slow, dense wind, contributing to the nebula’s present-day structure.

The James Webb Space Telescope has pointed its infrared optics at the 'Crystal Ball Nebula' NGC 1514, a planetary nebula studied since the late 1800s.
