Astronomers using NASA’s Chandra X-ray Observatory have detected five X-ray events from G29-38, which is among the 100 closest white dwarfs. Their results...
Dr. Chengcai Shen from the Harvard & Smithsonian Center for Astrophysics and colleagues have analyzed images of the so-called supra-arcade downflows...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found thousands of dense gas clumps but, surprisingly, no star formation,...
Astronomers using the NASA/ESA Hubble Space Telescope have measured the metallicity of the neutral interstellar medium towards 25 bright stars in our Milky...
The rapidly rotating, strong magnetic field of Jupiter provides a natural lab that is key to understanding the dynamics of high-energy plasmas. Spectacular...
Launched in September 1977, NASA’s Voyager 1 spacecraft flew by Jupiter in 1979 and then Saturn in late 1980. In August 2012, it crossed the heliopause...
Astronomers using ESO’s Very Large Telescope (VLT) have produced a spectacularly detailed image of a bubble of hot hydrogen gas called Sharpless 2-305...
Hurricanes in the Earth’s low atmosphere are well known; however, disturbances resembling hurricanes had never before been detected in the upper atmosphere.
An...
Using CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) and background radio galaxies, astronomers have spotted a long cloud of cold hydrogen...
Spinning black holes store rotational energy that can be extracted; when a black hole is immersed in an externally supplied magnetic field, reconnection...
Using X-ray data from NASA’s HaloSat minisatellite, astronomers have found that our Milky Way Galaxy is surrounded by a clumpy halo of hot gases that...
The crusts of the Moon, Mercury and many small bodies in the Solar System are magnetized. Although the magnetizing field is commonly attributed to that...
Astronomers using the Australia Telescope Compact Array (ATCA) have detected plasma jets coming from a supermassive black hole in the central galaxy of...
In a new study published in the journal Nature Astronomy, a team of planetary researchers from the United States and France studied the photochemical role...
Uranus possesses an intrinsic magnetic field that encircles the ice giant and influences the local space environment. The solar wind plasma, made up of...
The high-resolution images from the National Science Foundation’s Daniel K. Inouye Solar Telescope, on the summit of Haleakala, Hawai’i, show a close-up...
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....
