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...

Brett Smith for redOrbit.com - Your Universe Online Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small-scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space, according to a new report in the journal Nature Physics. "Magnetic fields are ubiquitous in the universe," said study author Don Lamb, a professor in astronomy and astrophysics at the University...

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....

Astronomers Discover Drastic Chemical Change In The Birth Of A Planetary System
2014-02-14 04:33:39

Lee Rannals for redOrbit.com - Your Universe Online A team of scientists led by the University of Tokyo say that the chemical compositions of an interstellar cloud and the disk are not identical. Stars are formed by the contraction of interstellar gas and dust, and this mix ends up helping to eventually form planets. However, scientists have wondered whether the chemical compositions of the interstellar cloud and the disk that creates the planets are identical. The latest findings,...

Massive Star Formation Mystery Solved
2014-01-28 04:04:20

Brett Smith for redOrbit.com - Your Universe Online Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards. According to a new study in The Astrophysical Journal Letters, a group of scientists using the Jansky Very Large Array (VLA), a radio observatory in New Mexico, has validated theories that say as the gas cloud...

[ 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...

USRA-led team finds polarized starlight implicates interstellar dust as host of hydrogen molecule formation, allows tracing magnetic fields in space. Columbia, MD1 (PRWEB) September 25, 2013 In a paper published in the Oct. 1, 2013, issue of The Astrophysical Journal, an integrated team of observers and theoreticians led by USRA astronomer Dr. B-G Andersson, has used telescopes in Spain, Hawaii, Arizona, and New Mexico, to show – for the first time – that intense molecular hydrogen...

Mapping Location Of Galactic Clouds

[ Watch the Video: Mapping Our Milky Way Galaxy ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the 22-meter Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born. In January, wildfires destroyed the telescope's adjoining workshop, office and accommodations, but Mopra's control room was spared because it was encased in brick. The team from the University of New South Wales (UNSW) wrote in the journal Publications of...

UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

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...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Emission Nebula -- In astronomy, emission nebulae are clouds of ionized gas, emitting light of various colors. The most common source for ionization are high-energy photons emitted from a nearby young, hot star. Usually, a young star will ionize part of the same cloud from which it was born. Only big, hot stars can release the amount of energy required to ionize a significant part of a cloud. Often, an entire cluster of young stars is doing the work. The nebula's color depends on...
