WISE Birthday Image
2013-12-13 15:43:15

Brett Smith for redOrbit.com - Your Universe Online To coincide with the fourth anniversary of NASA’s Wide-Field Infrared Survey Explorer (WISE) mission, the space agency has released an image showing a unique juxtaposition – a distant, dying star called the Helix nebula, surrounded by a halo of relatively close asteroids tracks. The release of the image and the mission’s fourth anniversary comes after NASA brought WISE out of hibernation back in August to search for more...

DARPA Is At Work Developing The Latest High-Tech Spy Satellite
2013-12-10 13:19:11

[ Watch the video: DARPA MOIRE Concept Video ] Lee Rannals for redOrbit.com - Your Universe Online DARPA says it has plans to develop an ultimate spy satellite capable of viewing 40 percent of the Earth’s surface at once. The Membrane Optical Imager for Real-Time Exploitation (MOIRE) space telescope will be launched as a tightly packed cluster of petals 20 feet in diameter, helping it stretch out to 68 feet across. It will record the Earth’s surface with high resolution imagery,...

Looking At Magnetic Fields Of Gamma-ray Bursts
2013-12-04 16:25:22

NASA A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team of astronomers from Britain, Slovenia and Italy has glimpsed the infrastructure of a burst's high-speed jet. Gamma-ray bursts are the most luminous explosions in the cosmos. Most are thought to be triggered when the core of a massive star runs out of nuclear fuel, collapses...

ESA Missions Will Seek To Understand The Evolution Of The Universe
2013-11-29 07:25:17

April Flowers for redOrbit.com - Your Universe Online The European Space Agency (ESA) announced today that the hot and energetic Universe and the search for elusive gravitational waves will be the focus of their next two large science missions. Bridging fundamental astrophysics and cosmology themes, both topics will closely study the processes that are crucial to the large-scale evolution of the Universe and its underlying physics. L2, the second large-class mission in ESA's Cosmic...

Non-Astronomy Scientists May Help Answer Cosmology Conundrum
2013-11-28 06:41:07

April Flowers for redOrbit.com - Your Universe Online Measuring the invisible and intangible is a challenge for sure, but scientists have made inroads on one front: the study of dark matter and dark energy, two of the most mysterious substances in the cosmos. Although dark matter is intermixed with normal matter, it gives off no light, making it impossible to see. Dark energy presents even more challenges, yet researchers believe it works against gravity to pull our universe apart at...

NuSTAR Helps Scientists Hunt For Medium-Sized Black Holes
2013-11-27 15:39:33

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) is helping scientists determine whether black holes need a medium-sized category. Black holes are known to either come in masses of only about 10 times that of our sun, or the equivalent in mass of up to 10 billion suns. However, NuSTAR could be finally finding a middle ground. "Exactly how intermediate-sized black holes would form remains an open issue," Dominic Walton, of the...

New Images Of Comet ISON
2013-11-27 15:08:31

[ Watch the Video: SOHO Sees Comet ISON Appear ] NASA As Comet ISON heads toward its closest approach to the sun — known as perihelion — on Nov. 28, 2013, scientists have been watching through many observatories to see if the comet has already broken up under the intense heat and gravitational forces of the sun. The comet is too far away to discern how many pieces it is in, so instead researchers carefully measure how bright it is, which can be used to infer its current state....

Sunny Outlook For NASA Kepler's Second Light
2013-11-26 12:09:10

NASA You may have thought that NASA's Kepler spacecraft was finished. Well, think again. A repurposed Kepler Space telescope may soon start searching the sky again. A new mission concept, dubbed K2, would continue Kepler's search for other worlds, and introduce new opportunities to observe star clusters, young and old stars, active galaxies and supernovae. In May, the Kepler spacecraft lost the second of four gyroscope-like reaction wheels, which are used to precisely point the...

NASA's Solar Observing Fleet Will Be Watching Comet ISON's Journey Around The Sun
2013-11-23 08:07:02

NASA It began in the Oort cloud, almost a light year away. It has traveled for over a million years. It has almost reached the star that has pulled it steadily forward for so long. On Thanksgiving Day, Nov. 28, 2013, Comet ISON will finally sling shot around the sun. Here its inward journey through the solar system will end -- either because it will break up due to intense heat and gravity of the sun, or because, still intact, it speeds back away, never to return. Catalogued as C/2012...


Word of the Day
siliqua
  • A Roman unit of weight, 1⁄1728 of a pound.
  • A weight of four grains used in weighing gold and precious stones; a carat.
  • In anatomy, a formation suggesting a husk or pod.
  • The lowest unit in the Roman coinage, the twenty-fourth part of a solidus.
  • A coin of base silver of the Gothic and Lombard kings of Italy.
'Siliqua' comes from a Latin word meaning 'a pod.'
