Planet-Forming Dust Abruptly Disappears Around Star
2012-07-05 05:10:33

Lee Rannals for redOrbit.com - Your Universe Online One star pinpointed as a prime location for a planet-forming disk decided enough was enough, and closed-up shop suddenly. While observing TYC 824126521, a young star located about 456 light years from Earth, researchers discovered that the planet-forming dust that once surrounded the star abruptly disappeared. Between 2008, when the star was being observed by a powerful infrared telescope in Chile, and 2010, when NASA's WISE...

Enceladus Plume Highlights 'Dusty Plasma'
2012-06-04 07:20:05

Recent findings from NASA's Cassini mission reveal that Saturn's geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed "dusty plasma," a condition theorized but not previously observed on site, near Enceladus. Data from Cassini's fields and particles instruments also show that the usual "heavy" and "light" species of charged particles in normal plasma are...

APEX Captures Stunning Image Of Dust Near Orion's Belt
2012-05-02 12:52:36

[ Video 1 ] | [ Video 2 ] A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion´s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. The observations, made with the Atacama Pathfinder Experiment (APEX) telescope[1], use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. Dust may sound boring and uninteresting – the surface grime that hides the beauty...

WISE Catches Cosmic Dust Bunny
2012-04-27 03:13:54

Images from NASA's Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life. The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky....

Dying Stars Are The Building Blocks Of Future Planets
2012-04-12 08:42:25

Lawrence LeBlond for RedOrbit.com Scientists report in a new study that they have solved a long-standing mystery about how dying stars release their precious matter, compounds that are an important ingredient in the building blocks of future planets. Their discovery was made after observing the violent ends of three ℠red giants´ having their atmospheres ripped away by super winds containing dusty grains of silica, producing massive sandstorms in space. These grains were...

Scientists Analyze Tiny Comet Grain To Date Jupiter's Formation
2012-03-02 04:12:19

Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System. The new finding helps test Solar System formation theories, which do not agree on the timing of Jupiter though it is certain the formation of this giant planet affected how materials moved, collided, and coalesced during the complex planet-forming process. Published in the February 1, 2012...

Study Finds Space Dust Gives Asteroids Their Shape
2012-02-28 12:10:28

Japanese researchers discovered while studying grains of dust from the Itokawa asteroid that tiny particles of space dust bombard asteroids and give them their shape. The researchers analyzed the size, mineralogy, shape and geochemistry of five dust grains recovered by the Japanese asteroid probe Hayabusa. Hayabusa succeeded in returning over 1,500 grains of dust from the asteroid Itokawa when it parachuted into the Australian outback in June 2010. "Our findings show the landscape...

Image 1 - APEX Images Cosmic Dust Filament Light-years Long
2012-02-15 06:23:25

[ Video 1 ] | [ Video 2 ] Star formation in “dark markings of the sky” A new image from the APEX (Atacama Pathfinder Experiment) telescope in Chile shows a sinuous filament of cosmic dust more than ten light-years long. In it, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars. It is one of the regions of star formation closest to us. The cosmic dust grains are so cold that observations at wavelengths of around one...

Image 1 - New 'Alien' Particles Have Entered Our Solar System
2012-01-31 13:59:55

[ Watch the Video ] Researchers have measured neutral "alien" particles that have entered our solar system from interstellar space. The team used NASA's Interstellar Boundary Explorer (IBEX) spacecraft to find the neutral particles, which make up about half the material outside the heliosphere. The heliosphere is the bubble in which our Sun and planets reside and is formed by the interaction between the solar wind and the interstellar medium. Electrically charged particles cannot...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
