New research also suggests that dust transport from the Sahara to the Eastern Atlantic Ocean, which could be further transported downstream towards the...
The debris cloud in the terrestrial zone of the 10-million-year-old star HD 166191 was created by a large impact involving objects of several hundred kilometers...
Astronomers using the Multi AperTure mid-Infrared SpectroScopic Experiment (MATISSE) on ESO’s Very Large Telescope Interferometer have spotted a dense,...
Solar system’s gas giants, such as Jupiter, Saturn, and massive exoplanets, were formed via the gas accretion onto the solid cores, each with a mass...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a unique object of uncertain nature — possibly a disintegrating...
Iodine, the same chemical added as a nutrient to table salt, is an atmospheric trace element emitted from oceans that efficiently destroys ozone. Low ozone...
The solar wind, comprised of solar particles largely made of hydrogen ions, created water on the surface of dust grains carried on asteroids that smashed...
CW Leonis, which is located 400 light-years away in the constellation of Leo, is a carbon star — a luminous type of red giant star with a carbon-rich...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered two heavily dust-obscured star-forming galaxies — REBELS-12-2...
Massive galaxies in the early Universe should have contained large amounts of cold molecular gas, the fuel required to make stars. But new observations...
Astronomers using the NASA/ESA Hubble Space Telescope have measured the metallicity of the neutral interstellar medium towards 25 bright stars in our Milky...
Astronomers using data from NASA’s Spitzer Space Telescope have looked for dust-extinguished supernovae in the nuclear regions of 40 luminous and ultra-luminous...
Betelgeuse, which is located roughly 724 light-years away in the constellation of Orion, is the second-closest red supergiant to Earth. From November 2019...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected a galactic-scale supermassive black hole-driven wind in HSC J124353.93+010038.5...
In a new paper published in the journal Earth and Planetary Science Letters, an international team of researchers presents the results from a long-term...
Two teams of astronomers have performed polarimetric observations of 2I/Borisov, the first active extrasolar comet ever detected in our Solar System, using...
The zodiacal light is sunlight reflected by interplanetary dust in the inner Solar System. Variations in the zodiacal light with ecliptic latitude reveal...
Geologists believe they have closed the case of what killed non-avian dinosaurs at the end of the Cretaceous period.
This painting depicts an asteroid...
The source of hydrogen chloride (HCl) in the atmosphere of Mars is recent surface volcanism, subsurface magmatic activity, or aerosol chemistry occurring...
