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...

asteroid defies gravity
2014-08-14 12:40:33

Whitney Heins, University of Tennessee at Knoxville Researchers at the University of Tennessee at Knoxville (UT) have made a novel discovery that may potentially protect the world from future collisions with asteroids. The team studied near-Earth asteroid 1950 DA and discovered that the body, which rotates so quickly it defies gravity, is held together by cohesive forces, called van der Waals, never before detected on an asteroid. The findings, published in this week’s edition of...

supernova SN 2014J
2014-08-14 10:48:55

NASA/Harvard-Smithsonian Center for Astrophysics New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in decades. The data gathered on the Jan. 21 explosion, a Type Ia supernova, allowed scientists to rule out one possible cause. These supernovas may be triggered when a white dwarf takes on too much mass from its companion star,...

Perseid meteor from space

Melissa Gaskill, International Space Station Program Office, NASA Johnson Space Center Those who enjoy the spectacle of the Perseids, Geminids or other annual meteor showers likely aren’t thinking about where these shooting stars originated or whether they might pose a danger. Scientists, however, think about such things and will use the vantage point of a special window on the International Space Station to learn more about the composition and behavior of meteors and their parent...

Dr. Tony Phillips, Science@NASA On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away - which would be like a comet passing about 1/3 of the distance between Earth and the Moon. The nucleus of the comet won't hit Mars, but there could be a different kind of collision. "We hope to witness two atmospheres colliding," explains David Brain of the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). "This is a once in a lifetime event!"...

supermassive black hole
2014-08-13 04:34:03

April Flowers for redOrbit.com - Your Universe Online An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The corona of the black hole, a compact source of X-rays that is situated nearby, has moved closer to the black hole over a period of just days. "The corona recently collapsed in toward the black hole, with the result that the black hole's intense gravity...

hunting for exomoons
2014-08-12 08:51:02

University of Texas at Arlington Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists from The University of Texas at Arlington believe following a trail of radio wave emissions may lead them to that discovery. Their recent findings, published in the Aug. 10 issue of The Astrophysical Journal, describe radio wave emissions that...

Elizabeth Zubritsky and Nancy Neal-Jones, NASA’s Goddard Space Flight Center A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved. [ Watch: HCN – Inner Coma Of C/2012 F6 (Lemmon) ] “We achieved truly first-of-a-kind mapping of important molecules that help us understand the nature of comets,” said Martin Cordiner, a researcher working in the...

Large Synoptic Survey Telescope
2014-08-10 02:05:44

National Science Foundation Construction of the highly anticipated Large Synoptic Survey Telescope (LSST) can begin now that the National Science Foundation (NSF) has finalized funding. To be located in Chile, LSST is a proposed 8-meter wide-field survey telescope that will image the entire visible sky approximately twice per week, providing an unprecedented amount of information while transforming the emerging discipline of data-enabled science. LSST was the highest-ranked ground-based...

redOrbit Staff & Wire Reports - Your Universe Online One of the downfalls of space travel is that astronauts are limited in the types of food they can eat due to the low gravity environment, but researchers from Cornell University are reportedly working on a solution that could one day allow the men and women traveling to Mars or the moon to enjoy a home-cooked meal. According to Stacey Shackford, a writer for Cornell’s College of Agriculture and Life Sciences, postdoctoral...

Geometry
2014-01-02 10:21:51

Geometry is a branch of mathematics that is concerned with questions of shape, size, relative position of figures, and the properties of space. A mathematician who works in the geometry field is called a geometer. Geometry arose independently in numerous early cultures as a body of practical knowledge concerning areas, lengths, and volumes, with elements of a formal mathematical science emerging in the West as early as Thales. By the 3rd century BC, geometry was put into an axiomatic form by...

Stellar Astrophysics

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Ad Astra

Ad Astra is a quarterly-published journal of the National Space Society (NSS). The name “ad astra” means “to the stars.” The journal was established following the merger of the L5 Society and the National Space Institute, which formed the NSS in 1987. The NSS is a non-profit aerospace advocacy and educational institution based in Washington DC. On November 28, 2007, the NSS announced MM Publishing Inc. as the newest publisher of Ad Astra. MM Publishing officially took on the role...

Columbia launched from Kennedy Space Center on October 22, 1992 at 1:09 PM EDT and landed at Kennedy on November 1 at 9:05 AM EST. The shuttle orbited 159 times at an altitude of 163 nautical miles at an inclination of 28.45 degrees and travelled 4.1 million miles. The mission lasted 9 days, 20 hours, 56 minutes, and 13 seconds. The mission launched several satellites for international partners. The primary mission objectives were the deployment of the Laser Geodynamic Satellite II...
