Eventually, the white dwarf will completely cool, blow off its nebula, and fade into black lumps of carbon. The Sun will quietly become a black dwarf, producing no heat nor light. Did You Know?Only very heavy stars weighing more than a half dozen stars can become a black hole.Learn more...
The Oort Cloud is very distant from the Sun and it can be disrupted by the nearby passage of a star, nebula, or by actions in the disk of the Milky Way. Those actions knock cometary nuclei out of their orbits, and send them on a headlong rush toward the Sun. Oort Cloud Location Th...
It is unclear, and still debated, whether homochirality is botha necessary and a sufficient condition for life to occur. The detection of asymmetry in known stars and nebula, and celestial bodies like comets and meteorites, suggests that chirality occurs naturally, even without evidence of life. ...
The element is formed under the higher pressures and temperatures within the star when it expands to become a red giant. When the outer layers of the star are pushed away creating a planetary nebula, the fluorine travels along with the other gases into the interstellar medium eventually forming...

Nebula, any of the various tenuous clouds of gas and dust that occur in interstellar space. The term was formerly applied to any object outside the solar system that had a diffuse appearance rather than a pointlike image, as in the case of a star. This d
Orion Nebula, bright diffuse nebula, faintly visible to the unaided eye in the sword of the hunter’s figure in the constellation Orion. The nebula lies about 1,350 light-years from Earth and contains hundreds of very hot (O-type) young stars clustered a
