Interstellar Molecules Are Branching Out
2014-09-27 08:50:36

Max Planck Institute Scientists from the Max Planck Institute for Radio Astronomy (Bonn, Germany), Cornell University (USA), and the University of Cologne (Germany) have for the first time detected a carbon-bearing molecule with a "branched" structure in interstellar space. The molecule, iso-propyl cyanide (i-C3H7CN), was discovered in a giant gas cloud called Sagittarius B2, a region of ongoing star formation close to the center of our galaxy that is a hot-spot for molecule-hunting...

April Flowers for redOrbit.com - Your Universe Online Current theories suggest that rocky planets like Earth start their lives as microscopic bits of dust tinier than a grain of sand. Filaments of star-forming gas near the Orion Nebula might be full of pebble-sized particles, according to a new study released by astronomers using the National Science Foundation's (NSF) Green Bank Telescope (GBT). These pebbles are planetary building blocks 100 to 1,000 times larger than the dust...

redOrbit Staff & Wire Reports - Your Universe Online Newly-created maps of the material located between the stars in the Milky Way could help astronomers solve a nearly century-long mystery involving stardust, according to a new study published in the August 15 edition of the journal Science. Researchers from the University of Ljubljana in Slovenia and Johns Hopkins University in Baltimore, along with an international team of colleagues, claim their work demonstrates a new method of...

Stardust spacecraft

redOrbit Staff & Wire Reports - Your Universe Online Seven rare and microscopic particles of space dust collected by instruments onboard NASA’s Stardust mission could be the first samples of contemporary interstellar dust ever obtained by scientists, an international team of researchers report in Friday’s edition of the journal Science. The samples, which were gathered by Stardust’s aerogel and aluminum foil dust collectors, likely originated from outside of our solar system....

WASHINGTON, Aug. 14, 2014 /PRNewswire-USNewswire/ -- Seven rare, microscopic interstellar dust particles that date to the beginnings of the solar system are among the samples collected by scientists who have been studying the payload from NASA's Stardust spacecraft since its return to Earth in 2006. If confirmed, these particles would be the first samples of contemporary interstellar dust. http://photos.prnewswire.com/prnvar/20081007/38461LOGO A team of scientists has been combing...

Supernova Explosions Release Building Blocks Of Planet Formation
2014-07-10 10:13:49

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The formation of planets of stars is still somewhat of a mystery to astronomers. While much progress has been made, particularly in the last few decades, there are still unanswered questions as to how the planetary building blocks form. But now, new research may be closing that knowledge gap. Early in the life of the Universe, the cosmos was dominated by the basic elements of hydrogen and helium, with only trace amounts of...

Planetary Nebulae Observed Releasing Water-Building Molecules
2014-06-17 11:19:05

Brett Smith for redOrbit.com - Your Universe Online The region in space around a planetary nebula is filled with harsh radiation. Yet despite this hostile environment – the area is seeded with a molecule essential to the formation of water. According to two new studies -- "Herschel Planetary Nebula Survey" and "Herschel spectral mapping of the Helix nebula" -- based on observations from the European Space Agency’s Herschel Observatory, harsh radiation around a planetary nebula does...

WASHINGTON, May 7, 2014 /PRNewswire-USNewswire/ -- A team of scientists at NASA's Ames Research Center in Moffett Field, Calif., has successfully reproduced, right here on Earth, the processes that occur in the atmosphere of a red giant star and lead to the formation of planet-forming interstellar dust. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Using a specialized facility, called the Cosmic Simulation Chamber (COSmIC) designed and built at Ames, scientists now are able to...

Magnetic Fingerprint Of Our Galaxy Revealed By Planck
2014-05-06 03:21:32

ESA Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarized' light emitted by interstellar dust in the Milky Way. Light is a very familiar form of energy and yet some of its properties are all but hidden to everyday human experience. One of these – polarization – carries a wealth of information about what happened along a light ray's path, and can be exploited by astronomers....

New Techniques Tease Out Building Blocks Of Life In Meteorites
2014-02-04 06:24:52

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...

Interstellar Cloud -- Interstellar cloud is the generic name given to accumulations of gas and dust in our galaxy. Depending on the density, size and temperature of a given cloud, the hydrogen in it can be neutral (HI clouds) or molecular (molecular clouds). Chemical compositions Analysing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them. Large radio telescopes scan the intensity in the sky of particular frequencies of...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...
