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...

Peculiar Dust Belts Found Around Six Stars
2013-07-10 05:19:51

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Besides the planets, comets, and asteroids that orbit our Sun, there are belts of rock and ice. Within these belts are dust particles, some which are fractions of a millimeter in size. As scientists have studied the heavens, they have located such disks orbiting other stars. "At least one fifth of stars are surrounded by dust belts like these," Alexander Krivov from the Friedrich-Schiller-University Jena explains. "They are...

Black Hole Observed Pushing Matter Away, Rather Than Consuming It
2013-06-20 06:27:46

Lawrence LeBlond for redOrbit.com - Your Universe Online Observations of a nearby active galaxy using the Very Large Telescope Interferometer (VLTI) at ESO´s Paranal Observatory in Chile have shown astronomers something they hadn´t expected to see. Astronomers have found over the past twenty years that nearly all galaxies have a black hole at their center, some of which grow by drawing in matter from their surroundings. This growth process creates some of the most energetic objects...

While Comet ISON’s eagerly anticipated encounter with the sun won’t even happen until November, it seems as though the fireball is already prepping a special encore performance for stargazers here on Earth.

[WATCH VIDEO: Comet ISON Meteor Shower] redOrbit Staff & Wire Reports - Your Universe Online While Comet ISON´s eagerly anticipated encounter with the sun won´t even happen until November, it seems likely the fireball is already prepping a special encore performance for stargazers here on Earth. In January, the US space agency´s Swift spacecraft observed the comet ISON while it was still near the orbit of Jupiter. Even then, it had already become extremely...

Airborne Observatory Reveals Mystery Of Star Formation
2013-04-17 11:52:24

Brett Smith for redOrbit.com - Your Universe Online Using observations from an airborne observatory, NASA researchers have discovered new details on how massive stars form within a cloud of interstellar gas and dust. An emerging star known as G35 has been observed forming in an orderly process similar to the one undergone by smaller stars like our sun, according to the scientists´ report in the Astrophysical Journal. Lead author Yichen Zhang said the observations of G35 made...

Astronomers Spot 'Soccer Ball' Molecules In Space
2013-03-05 13:10:23

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers are reporting in The Astrophysical Journal they have spotted what resembles a soccer ball sitting in the dying star M1-11. Five instruments helped astronomers detect C60 fluorine in the dying star, which are molecules of carbon with 60 atoms arranged in patterns that resemble a soccer ball. Astronomers used the Subaru Telescope, the Spitzer Space Telescope (SST), ESO's Very Large Telescope, the...

Space Dust Likely Culprit Behind Fallen Satellites
2013-02-27 12:00:13

Lee Rannals for redOrbit.com - Your Universe Online According to an aeronautics and astronautics professor at Stanford University, "space dust" is the likely culprit behind why satellites fail. Satellites are threatened by both asteroids and "space junk," which are particles of man-made debris that orbit Earth. However, the threat from these impacts is actually relatively low, and most satellites that have died in space were knocked out by something entirely different. Space dust,...

Astronomers Capture Rare Glimpse Of Star-Forming Region In Visible Light
2013-01-16 07:00:46

[Watch Videos: 1 - Zooming in on Lupus 3 / 2 - Panning Over Lupus 3] Lawrence LeBlond for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery. The new image, taken with MPG/ESO 2.2-meter telescope at La Silla Observatory in Chile, is one of the finest and clearest ever taken in visible light of...

Planet Forming Gas Streams Revealed

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. Astronomers who made observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope are helping to shed light on planet-forming gas streams. The international team of astronomers studied the young star HD 142527, seeing a key...

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...
