IBEX spacecraft images the heliotail, revealing an unexpected structure
(Phys.org) —NASA's Interstellar Boundary Explorer (IBEX) spacecraft recently provided the first complete pictures of the solar system's downwind region, revealing a unique and unexpected structure.
Loopholes discovered in Sun's magnetic belt
(Phys.org)—The mystery surrounding how an electrically charged solar wind can be unleashed from around the Sun's equator – an area where strong magnetic fields should strap it to the surface – has ...
Rosetta image demonstrates the unpredictable nature of comets
(Phys.org) —An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects.
Measuring Mars: The MAVEN magnetometer (w/ video)
When the Mars Atmosphere and Volatile Evolution (MAVEN) mission begins its journey to the Red Planet in 2013, it will carry a sensitive magnetic-field instrument built and tested by a team at NASA's Goddard ...
NASA scientists build first-ever wide-field X-ray imager
(Phys.org)—Three NASA scientists teamed up to develop and demonstrate NASA's first wide-field-of-view soft X-ray camera for studying "charge exchange," a poorly understood phenomenon that occurs when the ...
Solar plane poised for last flight of US journey
For Swiss pilot Bertrand Piccard, flying an experimental solar aircraft across America has been exhilarating, but perilous at times.
Electric Moon jolts the solar wind
(Phys.org) -- With the Moon as the most prominent object in the night sky and a major source of an invisible pull that creates ocean tides, many ancient cultures thought it could also affect our health or ...
NASA's next Mars rover will advance hunt for past life
The next robotic rover to explore Mars in 2020 should scour the surface of the red planet more closely than ever for signs of past life, a NASA science team said Tuesday.
Uranus auroras glimpsed from Earth
(Phys.org) -- For the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. Detected by means ...
NASA invites the public to fly along with Voyager
(Phys.org) —A gauge on the Voyager home page, http://voyager.jpl.nasa.gov, tracks levels of two of the three key signs scientists believe will appear when the spacecraft leave our solar neighborhood and ...
Wind mission encounters 'SLAMS' waves
(Phys.org) —As Earth moves around the sun, it travels surrounded by a giant bubble created by its own magnetic fields, called the magnetosphere. As the magnetosphere plows through space, it sets up a standing ...
Space environmentalist warns we need to better prepare for solar storms
'Deflector Shields' protect the Lunar Surface
