Magnetic activity on the Sun leads to solar flares, coronal mass ejections, and other space weather that affects Earth. Similar activity on other stars...
Brown dwarfs are cool, dim objects that have a size between that of a gas giant, such as Jupiter or Saturn, and that of a Sun-like star. Sometimes called...
Gamma-ray bursts are the most energetic explosions in the Universe, beaming out huge jets of light-emitting plasma, which travel through space at 0.99...
Uranus possesses an intrinsic magnetic field that encircles the ice giant and influences the local space environment. The solar wind plasma, made up of...
In a new study published in the journal Earth and Planetary Science Letters, a team of researchers from the Scripps Institution of Oceanography at the...
In a paper in the journal Physical Review Letters, an international team of physicists reports the most precise measurement ever made of the electric dipole...
Using data from the European Photon Imaging Camera (EPIC) onboard ESA’s XMM-Newton X-ray observatory, astronomers have detected for the first time a...
Solar Orbiter, a new collaborative mission between ESA and NASA to study our Sun, successfully launched on an Atlas V 411 rocket from Cape Canaveral Air...
Using the Low Frequency Array (LOFAR) radio telescope, astronomers have observed radio waves that carry the distinct signatures of extraterrestrial aurorae,...
At the end of its mission in 2017, NASA’s Cassini spacecraft performed a set of ‘Grand Finale’ orbits bringing it closer to Saturn than ever before....
Researchers from NOAA’s National Centers for Environmental Information and the British Geological Survey earlier this month released a new version of...
New infrared observations from NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) of Messier 77, a spiral galaxy located 47 million light-years...
For more than six decades, observations of our Sun have shown that as magnetic waves leave its interior they grow in strength, but until now there has...
Astronomers using NSF’s Karl G. Jansky Very Large Array (VLA) have captured a new image of the edge-on barred spiral galaxy NGC 4631 (also known as ‘Whale...
In a new study published in the journal Astronomy & Astrophysics, Dr. Juan Soler of the Max Planck Institute for Astronomy used observations from ESA’s...
In November 2018, CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) detected a new fast radio burst, an enigmatic blast of cosmic radio waves...
Earth’s magnetic field is produced in the planet’s liquid iron outer core as it spins around the solid inner core, and protects the surface from harmful...
