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...

star formation region Gum 15
2014-07-02 10:48:50

European Southern Observatory The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mold the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her. This image was taken as part of the ESO Cosmic Gems program [1] using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It shows Gum 15, located in the...

Computing Asteroid Paths For Future Exploratory, Redirect Missions
2014-07-01 12:19:30

Gerard LeBlond for redorbit.com - Your Universe Online Asteroids are chunks of debris left over from the solar system’s formation. They are a substantial interest to scientists, having possible resources embedded within them. Water, along with other resources found on these asteroids would be a benefit to astronauts traveling into deep space with missions to Mars and even deeper in our solar system. Currently, NASA is developing methods needed for a 2030s mission to Mars. In the...

cassini grand finale
2014-07-01 06:45:49

Preston Dyches, NASA Jet Propulsion Laboratory With input from more than 2,000 members of the public, team members on NASA's Cassini mission to Saturn have chosen a name for the final phase of the mission: the Cassini Grand Finale. Starting in late 2016, the Cassini spacecraft will begin a daring set of orbits that is, in some ways, like a whole new mission. The spacecraft will repeatedly climb high above Saturn's north pole, flying just outside its narrow F ring. Cassini will probe the...

European Space Agency Selects Athena Advanced Telescope For Study Of High-Energy Astrophysics
2014-06-27 09:41:59

Gerard LeBlond for redOrbit.com - Your Universe Online The European Space Agency (ESA) is in the process of launching a second “Large-class” mission to explore the universe for high-energy astrophysics and selected the Athena advanced telescope for the task. The mission is scheduled for launch in 2028 to study the hot and energetic Universe as part of ESA’s Cosmic Vision 2015 to 2025 plan. Athena is a large X-ray telescope combined with state-of-the-art scientific instruments...

Potentially Habitable Exoplanet With Earth-Like Temperatures Found
2014-06-27 08:24:53

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a new, potentially habitable Super-Earth believed to possess temperatures comparable to those found here, but with much larger seasonal shifts, provided the atmosphere is similar to our planet's own. Dr. Robert A. Wittenmyer, a researcher at UNSW Australia specializing in the detection and characterization of extrasolar planets, and his colleagues located the new Super-Earth in orbit around the nearby...

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...

Planetary Astronomy

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
2012-05-07 07:06:15

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...
