Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two...
Using data from the NASA/ESA Hubble Space Telescope and NASA’s retired Spitzer space telescope, astronomers have discovered that two exoplanets around...
Titan, the largest moon of Saturn, is the only moon in the Solar System with a dense atmosphere, and it is also the only planetary body other than Earth...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
Using images obtained by two orbiting spacecraft, NASA’s Mars Reconnaissance Orbiter and ESA’s Mars Express, planetary researchers analyzed textured...
Magnetars are neutron stars with ultra-strong magnetic fields, which can be observed in X-rays. Polarization measurements could provide information on...
The sample of material delivered to our planet from the near-Earth asteroid Ryugu contained a mixture of extraterrestrial (helium and neon) and terrestrial...
The annual ozone hole over the South Pole reached an average area of 23.2 million km2 (8.9 million square miles) between September 7 and October 13, 2022,...
The Earth’s atmosphere is always electrified to a greater or lesser extent, even in fair weather away from thunderstorms. By measuring the electrical...
