NASA Satellite Captures Spectacular Solar Eruption
2012-04-17 06:43:52

[ Watch the Video ] A NASA satellite yesterday captured spectacular images and video of a massive solar flare erupting from the eastern side of the Sun. The M1.7 (medium intensity) class solar “prominence eruption” produced a coronal mass ejection (CME) that was captured by NASA´s Solar Dynamics Observatory (SDO). The event occurred at 1:45 p.m. EDT on April 16, 2012. The ejection, impressive as it was, was only a moderate event by astronomy standards. Such flares...

Massive solar flares could bring down the national electrical grid and affect power in the U.S. “for a period of years,” according to a 2009 NASA report. On March 27th Jack Jobe, Emmy-nominated journalist and survival teacher, shows how to prepare yourself and your family on National Geographic´s “Doomsday Preppers.” Aurora, Colorado (PRWEB) March 24, 2012 National Geographic takes viewers inside the world of Jack Jobe, a “Common Sense Survival...

[ Watch the Video ] Solar storm dumps gigawatts into Earth's upper atmosphere A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles.  NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth´s upper atmosphere to power every residence in New York City for two years. “This was the biggest dose of heat we´ve received from a solar storm since 2005,” says Martin Mlynczak of...

Researchers Document Auroral Turbulence Using Nanosatellite Radar Receiver
2012-03-23 07:20:41

Researchers from SRI International and the University of Michigan have taken the first-ever measurement of naturally occurring auroral turbulence recorded using a nanosatellite radar receiver. The research was done with support from the National Science Foundation (NSF) and NASA's Educational Launch of Nanosatellites (ELaNa) Initiative. The distinctive radar echoes recorded on March 8 were taken with the Radio Aurora Explorer (RAX) CubeSat. The RAX nanonsatellite measured turbulence over...

R Darrah for RedOrbit.com [ Watch the Video ] NASA chief technologist Mason Peck and Congressman Dana Rohrabacher (R-CA) met with executives and engineers at L´Garde Inc. on Thursday, March 15 to see the company´s progress on providing an in-space demonstration of a large, mission-capable solar sail. L´Garde was one of only a handful of companies to have been awarded a NASA Technology Demonstration Mission (TDM) contract last year.  The program calls for the...

Solar Storm Threat Appears To Have Passed
2012-03-09 12:26:43

[ Watch the Solar Flare in Action Here and Here ] Two recent Coronal Mass Ejections (CMEs) -- massive bursts of solar wind produced by the Sun -- appear to have caused little or no damage to electrical systems, according to scientists. The CMEs were caught by NASA as they took off from the Sun, traveling faster than 1,300 miles per second. The first wave hit yesterday morning, March 8. The second hit late last night into early this morning. Joseph Kunches, a scientist with the...

CMEs Heading Towards Earth
2012-03-07 15:15:46

[ Watch the Solar Flare in Action Here and Here ] NASA said on Wednesday that two Coronal Mass Ejections (CMEs) are now traveling faster than 1,300 miles per second, on track towards Earth. NASA's Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) caught the CMEs as they took-off from the sun. The space agency said the first CME, which is traveling at about 1,300 miles per second, will reach Earth on the morning of March 8. This CME...

New System To Forecast Space Weather
2012-03-05 08:04:05

A new system has been developed by British scientists that will forecast space weather in an effort to better protect satellites orbiting our planet from damaging solar storms. Led by researchers at the British Antarctic Survey (BAS), the SPACECAST project is expected to provide reliable web-based forecasts so that satellite operators will be able to take action to keep their navigational, communication, and scientific satellites from the radiation that solar storms produce. Researchers...

Curiosity, The Astronaut Stunt Double
2012-02-25 05:28:49

[ Watch the Video ] With a pair of bug-eyes swiveling on a stalk nearly 8 feet off the ground, the 6-wheeled, 1800-lb Mars rover Curiosity doesn´t look much like a human being.  Yet, right now, the mini-Cooper-sized rover is playing the role of stunt double for NASA astronauts. “Curiosity is riding to Mars in the belly of a spacecraft, where an astronaut would be,” explains Don Hassler of the Southwest Research Institute in Boulder, Colorado.  “This...

RHESSI Mission Celebrates Ten Years And Forty Thousand X-Ray Flares
2012-02-11 04:00:56

[ Watch the Video ] On February 5, 2002, NASA launched what was then called the High Energy Solar Spectroscopic Imager (HESSI) into orbit. Renamed within months as the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) after Reuven Ramaty, a deceased NASA scientist who had long championed the mission, the spacecraft's job was to observe giant explosions on the sun called solar flares. During a solar flare, the gas soars to over 20 million degrees Fahrenheit, and emits X-rays that...

Photosphere -- The photosphere of an astronomical object is the region at which the optical depth becomes one. In other words, the photosphere is the place where an object stops being transparent. It is typically used to describe the Sun or another star. Because stars are large balls of gas, they have no solid surface. However, there is a depth at which the gas stops being transparent to photons, and this depth provides a visual surface to the star. The Sun's photosphere has a...

Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...

Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...

Solar Maximum -- The Sun, a roiling ball of plasma, occupies its place in space approximately 93 million miles from Earth. Though it seems simple to inhabitants of this planet -- the Sun shines, giving light and heat -- the processes occurring in the Sun are so complex that many scientists devote their careers to just one aspect of solar activity. Changes in the activity of the Sun particularly engage solar scientists. Whether fluctuations in the solar magnetic field, expulsions of...
