HESS-II telescope
2014-07-05 05:47:46

CNRS (Délégation Paris Michel-Ange) The HESS-II (High Energy Stereoscopic System) telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar. This is the first pulsar to be detected by HESS and the second - after Crab in 2011 - to be spotted by ground-based gamma ray telescopes. These results have been obtained by the HESS collaboration involving the CNRS and CEA. The HESS experiment in Namibia, which was upgraded in 2012, now boasts a fifth...

Using A Stellar Ultrasound To Determine Ages Of Young Stars
2014-07-04 11:40:33

Brett Smith for redOrbit.com - Your Universe Online Before they become full-fledged stars, young embryonic stars are essentially contracting molecular clouds of gas and dust particles. The age of these ‘baby stars’ is difficult to gauge, but a newly published study in the journal Science has revealed scientists used a technique similar to ultrasound technology to determine the age of these young stars. "Think of it as ultrasound of stellar embryos," explained study author Jaymie...

Planetary System Gliese 581
2014-07-04 06:31:29

redOrbit Staff & Wire Reports - Your Universe Online Gliese 581g, described as one of the most Earth-like planets when it was originally discovered four years ago, probably does not exist, researchers from Penn State University and the University of Texas at Austin report in the latest edition of the journal Science. Officially, lead author Paul Robertson of Penn State’s Center for Exoplanets and Habitable Worlds and his colleagues write that the existence of Gliese 581g is...

newly discovered planet in binary system
2014-07-04 04:31:19

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

NASA New Horizon Probe To Get Help From Hubble Space Telescope
2014-07-03 14:09:36

Brett Smith for redOrbit.com - Your Universe Online In 2006, NASA launched its New Horizons probe to explore the outer reaches of our Solar System and beyond. Fast forward eight years and the craft is now going to be getting a little direction with the help of the Hubble Space Telescope. The space agency announced on Wednesday that Hubble will begin searching for an ideal outer solar system object that New Horizons could fly by as it moves past Pluto in July 2015. The Hubble will...

Iron 'Fingerprints' Point Astronomers To Supernova Remnants
2014-07-03 03:27:00

NASA An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants, the expanding clouds of debris left behind when stars explode. The method provides scientists with a way to quickly identify the type of explosion and offers insights into the environment surrounding the star before its destruction. "Supernovae imprint their remnants with X-ray evidence that reveals the nature of the...

Stampede Supercomputer Simulations Used To Shed Light On Distant Explosions
2014-07-03 03:08:46

Aaron Dubrow, National Science Foundation Using the National Science Foundation-supported Stampede supercomputer, Philipp Moesta and Christian D. Ott from the California Institute of Technology succeeded in performing the first 3-D simulations of a collapsing star that takes into account the influence of general relativity and magnetohydrodynamics--the interplay of electrically conducting fluids like plasmas and powerful magnetic fields. The death of these collapsing stars leads to...

NASA/JPL Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory. Herschel is a European Space Agency mission with important NASA contributions. [ Watch the Video: Zooming In On Messier 106 ] Energetic jets, which blast from Messier 106's central black...

Ocean On Saturnian Moon Titan May Be As Salty As The Dead Sea
2014-07-03 10:00:08

Gerard LeBlond for redOrbit.com - Your Universe Online The inner ocean of Saturn’s largest moon Titan may be as salty as the Dead Sea, according to scientists with NASA’s Cassini mission, which has been collecting gravity and topographic data from the distant Saturnian satellite over the last ten years. After studying the data, researchers built a model structure of Titan, resulting in a better understanding of the moon’s outer ice shell. The study was published this week in the...

Umbrella Galaxy
2014-07-03 04:44:09

April Flowers for redOrbit.com - Your Universe Online Astronomers are hoping to gain a new understanding of how galaxies grow from watching a distant “twin” of the Milky Way as it is swallowing another galaxy. Dr. Caroline Foster of the Australian Astronomical Observatory (AAO) led the team that has been studying NCG 4651, called the Umbrella galaxy for the “parasol” of stars that are all that remain of the galaxy being consumed. Umbrella can be found approximately 62 million...

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...
