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

[ 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...

[ Watch the Video: What Could Be Raining Down Life In Our Solar System? ] redOrbit Staff & Wire Reports - Your Universe Online Dust that originates from comets, asteroids and leftover debris from the birth of the Solar System could deliver water and organic material to the Earth and other terrestrial planets, according to a recent Proceedings of the National Academy of Science paper. In the study, researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth...

Supernova Dust Factory

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

Critical Interplay Discovered Between Cosmic Dust, Magnetic Fields
2013-09-27 10:40:02

Brett Smith for redOrbit.com - Your Universe Online Interstellar magnetic fields can be found throughout the Milky Way and other similar galaxies. They are thought to be a key regulator in star formation and the propagation of cosmic rays. A new study published in The Astrophysical Journal has provided new insights for scientists looking to probe the strength and structure of these magnetic fields, a highly difficult phenomenon to accurately measure. To learn more about interstellar...

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...
