Latest Cosmic dust Stories
Astronomy & Astrophysics is publishing the first clear detection of signatures long sought in the spectra of X-ray astronomical sources, the so-called EXAFS signatures, standing for â€œExtended X-ray Absorption Fine Structure.â€
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II).
A team of astronomers, led by Loretta Dunne from the University of Nottingham, have found some very unusual stardust.
British astronomers say cosmic dust was partially created by the gradual death of carbon stars and not just from stars that exploded. The astronomers have been watching cosmic dust form around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, said a release from the Science and Technology Facilities Council, which funded the study. The newly observed dust formation was found around the carbon star MAG 29, located 280,000 light years away...
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust.
Stardust-NExT on Its Way to Explore Comet Tempel 1 DENVER, Jan. 13 /PRNewswire/ -- On Jan.
The Akari infrared surveyor, a Japanese Aerospace Exploration Agency mission with ESA participation, has returned a host of new results.
Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.
Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope.
The origin of the microscopic meteorites that make up cosmic dust has been revealed for the first time in new research out Sept. 1, 2008.
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
