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 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...

[ 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...

Molecular Cloud Explains Star Formation
2013-10-22 12:16:19

Brett Smith for redOrbit.com - Your Universe Online The molecular clouds that float about the universe hold the ingredients for star formation, and a new study from researchers at University of California, San Diego has confirmed the mechanics behind three observed relationships describing the internal forces acting within these clouds, called Larson’s Laws. First postulated in 1981 by Richard Larson, a professor of astronomy at Yale, Larson's Laws detail the observation-based...

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...

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...

Heliophysics Nuggets Help Map Tons Of Meteoric Dust In The Sky
2013-08-09 10:46:01

NASA Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth. On Aug.11 and 12, 2013, the annual Perseid meteor shower will peak, filling the sky with streaks of light, commonly known as shooting stars. Such visually stunning showers are actually but the tip of the iceberg when it comes to meteoroids slamming into Earth's...

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...
