[ 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...

Sweet Spots For The Formation Of Complex Organic Molecules In The Galaxy
2011-11-03 04:54:28

Scientists within the New York Center for Astrobiology at Rensselaer Polytechnic Institute have compiled years of research to help locate areas in outer space that have extreme potential for complex organic molecule formation. The scientists searched for methanol, a key ingredient in the synthesis of organic molecules that could lead to life. Their results have implications for determining the origins of molecules that spark life in the cosmos. The findings will be published in the Nov. 20...

RIT professor co-authors Nature article and Gemini Observatory's 1,000th paper The discovery of 13 diffuse interstellar bands with the longest wavelengths to date could someday solve a 90-year-old mystery. Astronomers have identified the new bands using data collected by the Gemini North telescope of stars in the center of the Milky Way. Nature reports on its website today findings that support recent ideas about the presence of large, possibly carbon-based organic...

Cleaning Up With Space Tech

  There´s just about nowhere that state-of-the-art space technologies cannot reach — from the martian atmosphere to those hard-to-clean spots under the couch. The search for space dust is giving us cleaner homes. Just ask Heinrich Iglseder, the Austrian scientist who created a technique to study dust in space that is now being used in a super-efficient Miele household vacuum cleaner. “Dust particles in space are very important to get information about how matter...

ESA's Herschel Space Observatory has detected cosmic dust from a supernova, adding to the theory that these cosmic fireworks are responsible for its creation. The astronomers who used Herschel to make the discovery said origin of the dust is important because it plays a crucial role in the formation of stars, particularly billions of years ago when star formation was at its peak.  "Interestingly, this brand new clue does not come from observations of very distant galaxies, but from one...

Genesis mission yields solar isotopic composition despite hard landing Two papers in this week's issue of Science report the first oxygen and nitrogen isotopic measurements of the Sun, demonstrating that they are very different from the same elements on Earth. These results were the top two priorities of NASA's Genesis mission, which was the first spacecraft to return from beyond the Moon, crashing in the Utah desert in 2004 after its parachute failed to deploy during re-entry. Most of the...

Nanoprobe reveals life history of meteorite from early solar system Scientists have performed a micro-probe analysis of the core and outer layers of a pea-sized piece of a meteorite some 4.57 billion years old to reconstruct the history of its formation, providing the first evidence that dust particles like this one experienced wildly varying environments during the planet-forming years of our solar system. The researchers interpret these findings as evidence that dust grains traveled over...

Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for making stars and for understanding how primordial diffuse gas clouds assemble themselves into full"“blown galaxies. "Formation of galaxies is one of the biggest remaining questions in astrophysics," said Andrey Kravtsov, associate professor in astronomy & astrophysics at the University of Chicago....

A University of Colorado at Boulder space dust counter designed, tested and operated by students that is flying aboard NASA's New Horizons mission to Pluto now holds the record for the most distant working dust detector ever to travel through space. The instrument on the New Horizons mission -- officially named the Venetia Burney Student Dust Counter, or SDC, after an 11-year-old English girl who named Pluto more than 75 years ago -- reached a distance of 1.67 billion miles from Earth on Oct....

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...
