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

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...

Meteorite violent origins
2014-08-09 05:13:23

April Flowers for redOrbit.com - Your Universe Online Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia (WA) side of Nullarbor Plain and was captured on camera. A new study, published in Geochimica and Cosmochimica Acta, indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid. The research team — comprised of Curtain University's Associate Professor Fred Jourdan, Professor Phil Bland and Dr....

Cassini spacecraft
2014-08-08 08:19:25

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft will execute the largest planned maneuver of the spacecraft's remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn's largest moon, Titan. The main engine firing will last about a minute and will provide a change in velocity of 41 feet per second (12.5 meters per second). This is the largest maneuver by Cassini in five years. No other remaining maneuver...

birth of the sun

Monash University Researchers are a step closer to understanding the birth of the sun. Published in Science, the team led by Dr Maria Lugaro and Professor Alexander Heger, from Monash University, have investigated the solar system's prehistoric phase and the events that led to the birth of the sun. Dr Lugaro, from the Monash Centre for Astrophysics, said the team used radioactivity to date the last time that heavy elements such as gold, silver, platinum, lead and rare-earth elements...

big bang black hole

Colin Hunter, Perimeter Institute for Theoretical Physics Our universe may have emerged from a black hole in a higher-dimensional universe, propose a trio of Perimeter Institute researchers in the cover story of the latest Scientific American. The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have a new idea about what might have come before the big...

Royal Astronomical Society A research team led by astronomers and astrophysicists at the University of Warwick have found that some of the Universe’s loneliest supernovae are likely created by the collisions of white dwarf stars into neutron stars. Dr Joseph Lyman from the University of Warwick is the lead researcher on the paper, which will appear in the journal Monthly Notices of the Royal Astronomical Society. "Our paper examines so-called 'calcium-rich' transients" says Dr Lyman....

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...

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...
