Latest Nebula Stories
A new image from NASA's Wide-field Infrared Survey Explorer shows what looks like a glowing jellyfish floating at the bottom of a dark, speckled sea.
Using NASA's Spitzer Space Telescope, astronomers have discovered bucket loads of buckyballs in space.
Enjoying a frozen treat on a hot summer day can leave a sticky mess as it melts in the Sun and deforms.
Unicorns and roses are usually the stuff of fairy tales, but a new cosmic image taken by NASA's Wide-field Infrared Explorer (WISE) shows the Rosette nebula located within the constellation Monoceros, or the Unicorn.
Astronomers scanning the skies as part of ESOâ€™s VISTA Magellanic Cloud survey have now obtained a spectacular picture of the Tarantula Nebula in our neighboring galaxy, the Large Magellanic Cloud.
The core technology developed for NASA's Nebula cloud computing platform has been selected as a contributor for OpenStack, a newly-launched open source cloud computing initiative.
A wave of massive star formation appears poised to begin within a mysterious, dark cloud in the Milky Way.
This magnificent view of the region around the star R Coronae Australis was created from images taken with the Wide Field Imager (WFI) at ESOâ€™s La Silla Observatory in Chile.
Using two of the worldâ€™s largest telescopes, an international team of astronomers have found evidence of a collision between galaxies driving intense activity in a highly luminous quasar.
A spectacular new NASA/ESA Hubble Space Telescope image â€” one of the largest ever released of a star-forming region â€” highlights N11, part of a complex network of gas clouds and star clusters within our neighboring galaxy, the Large Magellanic Cloud.
Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...
Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...
Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...
Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...
Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
