Images from one of the Magnetospheric Imaging Instrument’s sensors, the Ion and Neutral Camera (MIMI/INCA), on NASA’s Cassini spacecraft suggest that the heliosphere may not have the comet-like shape ...
Physics and Astronomy |"Nature is full of surprises, and IBEX has been lucky to discover one of those surprises," said Priscilla Frisch, a senior scientist in astronomy & astrophysics at the University of Chicago....
Physics and Astronomy |The solar wind engulves our solar system like a cocoon: This continuous plasma flow that emanates from the Sun is protecting us from the interstellar medium, especially from the cosmic rays. The bound...
Physics and Astronomy |"In 2009, cosmic ray intensities have increased 19% beyond anything we've seen in the past 50 years," says Richard Mewaldt of Caltech. "The increase is significant, and it could me...
Physics and Astronomy |The discovery could give a new insight into just how energy is dissipated in solar system sized plasmas such as the solar wind and could provide significant clues to scientists developing fusion powe...
Physics and Astronomy |For example, “satellites experience the disruptive effects of energetic charged particles and electrical charging across the satellite structure during various weather conditions. Astronauts are vulne...
Information Technology |NASA's Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of very fast hydrogen atoms coming from the moon, following decades of speculation and searching for their ...
Earth Sciences |This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will help astronomers relate the appearance of an ast...
Studies and Analyses |A team of Los Alamos researchers led by Victor Klimov has shown that carrier multiplication—when a photon creates multiple electrons—is a real phenomenon in tiny semiconductor crystals and not a false...
Life Sciences |Although it should take about a year to map the full sky, details from the satellite's first data will be reported at "Voyagers in the Heliosheath," a conference organized by The Univer...
Event News |The spacecraft's magnetometer instrument (MAG) detected the unmistakable signature of hydrogen gas being stripped from the day-side. “This is a process that was believed to be happening at Venus ...
Physics and Astronomy |The aurorae on Mars were discovered in 2004 using the SPICAM ultraviolet and infrared atmospheric spectrometer on board Mars Express. They are a powerful tool with which scientists can investigate the...
Physics and Astronomy |Space weather ingredients: flares overwhelming the Earth suddenly with an overdose of radiation, enormous and heavy plasma clouds rushing through space and finally hitting Earth, high-energetic partic...
Earth Sciences |New research, out today, Tuesday, November 4, published in IOP Publishing’s Plasma Physics and Controlled Fusion, shows how knowledge gained from the pursuit of nuclear fusion research may reduce the ...
Physics and Astronomy |Nature’s own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable nature’s laws to be studied in controlled experiments.The LHC ...
