Big Bang In High Fidelity Sound
2013-04-10 10:53:15

[ Watch the Video: The Sounds of the Big Bang in High Fidelity ] April Flowers for redOrbit.com - Your Universe Online "If the Universe started with a bang, and no one was alive yet to observe it, would it still make a sound?" It sounds like the start of a really cliché joke, but the answer, surprisingly, is yes. Scientists believe the expanding early Universe produced waves of sound that echoed through the dense plasma and hydrogen that filled it at the time....

NASA's Astrophysics Explorer Program has selected two missions for launch in 2017: a planet-hunting satellite and an International Space Station instrument to observe X-rays from stars. The Transiting Exoplanet Survey Satellite (TESS) and Neutron Star Interior Composition Explorer (NICER) were among four concept studies submitted in September 2012. NASA determined these two offer the best scientific value and most feasible development plans. TESS will use an array of telescopes to...

Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

NASA On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe. Up in the space surrounding Earth -- a space that seethes with its own space weather made of speeding charged particles and constantly changing magnetic fields that can impact satellites — there are only a handful of spacecraft to watch for solar and magnetic storms. The number of observatories has...

WISE Captures The Heat From Orion's Sword

NASA's Jet Propulsion Laboratory The tangle of clouds and stars that lie in Orion's sword is showcased in a new, expansive view from NASA's Wide-field Infrared Survey Explorer, or WISE. Orion, the famous hunter, is visible in evening skies throughout the world from about December through April. The constellation appears tranquil and still to the naked eye, but lying in its sword, at what appears to be a slightly fuzzy star, is a turbulent cauldron of stellar birth. WISE scanned the...

New Rocket Project Aims To Study Auroral Wind Of Northern Lights
2013-02-01 13:41:57

Lawrence LeBlond for redOrbit.com - Your Universe Online For many in the extreme upper latitudes of the Northern Hemisphere, the Aurora borealis (better known as the Northern Lights) offer breathtaking displays of color and lights, dancing effortlessly across the night sky. These lights, which are caused by solar winds bouncing off the Earth´s upper atmosphere, are typically visible only around the Polar ℠auroral zone´ due to the strong magnetic forces around this region....

NASA IRIS Spacecraft
2013-01-19 08:48:07

NASA NASA's next Small Explorer (SMEX) mission to study the little-understood lower levels of the sun's atmosphere has been fully integrated and final testing is underway. Scheduled to launch in April 2013, the Interface Region Imaging Spectrograph (IRIS) will make use of high-resolution images, data and advanced computer models to unravel how matter, light, and energy move from the sun´s 6,000 K (10,240 F / 5,727 C) surface to its million K (1.8 million F / 999,700 C) outer...

NASA NuSTAR Catches Glimpse Of Supernova Remnant, Black Holes
