ITHACA, N.Y. "“ 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. The findings are reported in the Jan. 16 issue of the journal Science (Vol. 323, No. 5912). Cornell research associate Greg Sloan led the study, which was based on observations with NASA's Spitzer Space Telescope. The researchers used Spitzer's Infrared Spectrograph,...

Stardust-NExT on Its Way to Explore Comet Tempel 1 DENVER, Jan. 13 /PRNewswire/ -- On Jan. 14, NASA's Stardust-NExT spacecraft will fly by Earth during a gravity assist maneuver that will increase its velocity and sling shot the spacecraft into an orbit to meet up with comet Tempel 1 in February 2011. Flight operations for the spacecraft are performed from Lockheed Martin's Mission Support Area in Denver, Colo. The Jet Propulsion Laboratory in Pasadena, Calif. provides the precision...

The Akari infrared surveyor, a Japanese Aerospace Exploration Agency mission with ESA participation, has returned a host of new results. From splashes in cosmic rivers of dust and gas to supernova remnants, the mission has been uncovering secrets of the cold and dusty Universe. Splashes in the interstellar medium The interstellar medium, a tenuous mix of gas and tiny solid dust particles, permeates space. As stars age, they spew out gas and dust in a flow called stellar wind, which eventually...

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. "It may be a while before we can directly image earthlike planets around other stars but, before then, we'll be able to detect the ornate and beautiful rings they carve in interplanetary dust," says Christopher Stark, the study's lead researcher at the...

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. Eli Dwek of NASA's Goddard Space Flight Center in Greenbelt, Md. and Richard Arendt of the University of Maryland, Baltimore County, say these echoes are powered by radiation from Cassiopeia A supernova shock wave that blew the star apart some 11,000 years ago. "We're seeing the supernova's first flash," Dwek said. Previously, other...

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. The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space. Cosmic dust particles, originally from asteroids and comets, are...

The Pinwheel galaxy is gussied up in infrared light in a new picture from NASA's Spitzer Space Telescope. The fluffy-looking galaxy, officially named Messier 101, is dominated by a mishmash of spiral arms. In Spitzer's new view, in which infrared light is color coded, the galaxy sports a swirling blue center and a unique, coral-red outer ring. A new paper appearing July 20 in the Astrophysical Journal explains why this outer ring stands out. According to the authors, the red color highlights...

NASA researchers and scientists from the United States, Germany and Japan have found a new mineral in material that likely came from a comet.The mineral, a manganese silicide named Brownleeite, was discovered within an interplanetary dust particle, or IDP, that appears to have originated from comet 26P/Grigg-Skjellerup. The comet originally was discovered in 1902 and reappears every 5 years. The team that made the discovery is headed by Keiko Nakamura-Messenger, a space scientist at NASA's...

Astronomers have discovered that rocky, terrestrial planets might orbit many, if not most, of the nearby sun-like stars in the disk of our galaxy. These new results suggest that worlds with potential for life are more common that we thought. This release is being issued jointly with the University of Arizona (UA). UA astronomer Michael Meyer (currently on sabbatical at the Harvard-Smithsonian Center for Astrophysics) used NASA's Spitzer Space Telescope to determine whether planetary...

University of Nottingham astronomers will be studying icy cosmic dust millions of light years away "” using the biggest space telescope ever built. Experts in the School of Physics and Astronomy will be using the Herschel Space Observatory, the most powerful telescope ever launched into space, as part of a giant survey to find out more about some of the coldest objects in the Universe. The Herschel Space Observatory, launched by the European Space Agency this Summer, promises to take...

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...
