ESA The largest census of dust in local galaxies has been completed using data from ESA’s Herschel space observatory, providing a huge legacy to the scientific community. Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets. But despite its importance, there is an incomplete picture of the dust properties in galaxies beyond our own Milky Way. Key questions include how the dust varies with the type of galaxy, and how...

Snake Nebula
2014-02-26 12:49:25

[ Watch the Video: Birth Of A Star A Family Affair ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Smithsonian's Submillimeter Array (SMA) telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula. The Snake nebula is about 11,700 light-years away from Earth towards the direction of the constellation Ophiuchus. The astronomers chose this nebula because it shows the potential to form many massive stars. "To learn how...

[ 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...

Spitzer's Citizen Science Zoo Displays New Animals
2013-12-17 08:17:13

NASA's Jet Propulsion Laboratory Since 2010, about 50,000 volunteers have taken to their computers to help astronomers catalog star-blown bubbles captured in images from NASA's Spitzer Space Telescope. Their efforts resulted in several scientific papers, and a deeper understanding of our Milky Way galaxy and its frothy star-forming clouds. Now, an updated version of the campaign, called the Milky Way Project, is releasing more images with a whole new set of "animals" to track in the...

Crab Nebula Surprises Astronomers With Noble Gas Molecules
2013-12-13 04:31:42

[ Watch the Video: Supernova Remnant Shows Signs Of Noble Gas ] redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the UK have discovered argon hydride within the Crab Nebula, marking the first time that noble gas molecules have been detected in space, according to research appearing in Friday’s edition of the journal Science. As part of their study, Mike Barlow of the University College London Department of Physics and Astronomy and his colleagues used the...

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...

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...
