The nebula is blue because the dust that causes its light tends to be more efficiently reflected. The same colour physics applied to Witch-Head also explains why our sky is blue. Ref:N.A.S.A. Planetary Nebula / Ghost Nebula Despite its name,planetary nebulae isn't anything to do with ...
Free Essay: Research from a star called Veil Nebula is being studied by scientists from NASA to discover how it has expanded since the eighteen years it has...
In these star-forming regions, the formations of gas, dust, and other materials cluster together to form denser regions. The density attracts matter and eventually becomes dense enough to create the formation of stars. The remaining material is then believed to form planets and other planetary sys...
Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off by a star as it collapsed to a white dwarf. (Image credit: NASA, ESA, J. Hester, A. Loll (ASU)) Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a ...
Planetary Nebula:Planetary nebulae are created when a star dies. They are formed by the outer layers of the dying star being ejected into space, which then form an expanding gas shell around the central starAnswer and Explanation: The color of a planetary nebula is determined by the type of...
The planetary nebula is a glowing record of the final death throes of the star. (Optical images are courtesy of the Magellanic Cloud Emission Line Survey (MCELS) team). Associate Professor Miroslav Filipović from the University of Western Sydney and his team argue that the detections of ...

A nebula ais one of the most beautiful deep-sky objects in the night sky. But what is a nebula? And how do these space clouds form?
are key laboratories in understanding the formation processes of a wide-range of astrophysical phenomena - a point well-illustrated by the fact that the only known double-degenerate, super-Chandrasekhar mass binary which will merge in less than a Hubble time is found inside a planetary nebula. He...
What is the mass of Betelgeuse? What elements fuse during planetary nebula formation? What galaxy is Rigel in? The explosion of a supernova typically leaves behind: a) a planetary nebula b) a shell of hot, expanding gas with a white dwarf at the center c) a shell of hot, expanding gas...
