A University of Arizona-led research team has measured the dynamics and ever-changing hot gas shell from where the solar wind originates. The study helps scientists answer fundamental questions about energy and matter moving through the heliosphere, affecting space weather events and planetary orbits.
Researchers have measured pressure at the edge of the solar system for the first time, finding it to be greater than expected. The pressure, caused by plasma, magnetic fields and particles like ions and cosmic rays, was calculated using observations of galactic cosmic rays from NASA's Voyager spacecraft.
Scientists have identified active faults in the Pacific Northwest region, which could produce earthquakes with magnitudes between 6 and 6.5. A volcano in Greece has also reawakened, causing significant swelling of the land near the caldera, suggesting an influx of magma into a chamber below the surface.
The Interstellar Boundary Explorer (IBEX) spacecraft has made significant discoveries about the interaction between the solar wind and interstellar space. The spacecraft has found that the strength of the interaction varies dramatically across the sky, with a long 'ribbon' and an intense hotspot detected in the heliosheath. These findi...
