2012-08-22 07:53:00

[WATCH VIDEO] Lawrence LeBlond for redOrbit.com - Your Universe Online NASA is launching twin satellites on August 24 from Cape Canaveral, Florida that will conduct the most intimate study to date of the Van Allen Radiation Belts that envelop Earth. The two-year Radiation Belt Storm Probes (RBSP) mission will study the extremes of space weather and should help scientists improve space weather forecasting. Space weather doesn´t seem like a big deal to most people on Earth, but,...

Johns Hopkins University professor Charles L. Bennett and members of the Wilkinson Microwave Anisotropy Probe (WMAP) space mission that he led will receive the Gruber Foundation´s 2012 Cosmology Prize in Beijing, China tomorrow. Bennett and the 26-member WMAP team will share the $500,000 prize and are being recognized by the foundation for their transformative study of an ancient light dating back to the infant universe. So precise and accurate are the WMAP results that they form the...

Lee Rannals for redOrbit.com - Your Universe Online While some find it as the source of inspiration for wrapping gifts, Scotch tape inspired one scientist at NASA to build a special X-ray mirror. NASA scientist Maxim Markevitch and a team of X-ray optics experts at the space agency's Goddard Space Flight Center are looking into the feasibility of creating a low-cost mirror out of plastic tape. "I remember looking at a roll of Scotch tape and thinking, 'was it possible to use the same...

NuSTAR Produces First Test Images
2012-06-29 13:09:03

Lee Rannals for redOrbit.com - Your Universe Online NASA said on Thursday that its Nuclear Spectroscopic Telescope Array (NuSTAR) has taken its first test images of a high-energy X-ray universe. The observatory is the first space telescope with the ability to focus high-energy X-rays, which are the same kind used by doctors and dentists, into images. The mission will begin with exploring hidden black holes, specifically looking for fiery cinder balls left over from star explosions....

NuSTAR To Help Scientists Solve Supernova Explosion Mystery
2012-06-18 04:01:37

[ Watch the Video ] Somewhere in the Milky Way, a massive old star is about to die a spectacular death. As its nuclear fuel runs out, the star begins to collapse under its own tremendous weight. Crushing pressure triggers new nuclear reactions, setting the stage for a terrifying blast. And then... nothing happens. At least that's what supercomputers have been telling astrophysicists for decades. Many of the best computer models of supernovas fail to produce an explosion. At the end of...

Lee Rannals for redOrbit.com Commercialized space industry has taken another step in collaboration with NASA as the space agency's NuSTAR telescope launched Wednesday morning. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) was launched in a unique way by The Orbital Science Corporation's "Stargazer" plane. Stargazer took off from Kwajalein Atoll, and released its Pegasus rocket, which carried NASA's NuSTAR the rest of the way towards space. "Pegasus is our most unique...
