Planetary scientists using spectral data from the NASA/ESA/CSA James Webb Space Telescope have confirmed the detection of hydroxyl molecules on the surface...
Using the FORCAST instrument on NASA’s retired Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have obtained mid-infrared spectra...
Scientists have determined a precise lead isotopic age of the andesitic achondrite meteorite Erg Chech 002. Their result, combined with published aluminum-26-magnesium-26...
Neptunian Trojans are trans-Neptunian objects in 1:1 mean-motion resonance with the ice giant Neptune. These asteroids are generally thought to have been...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected gaseous water in the planet-forming disk around V883 Orionis, a...
Planetary scientists from the ETH Zürich and elsewhere have determined palladium-silver (Pd-Ag) and platinum (Pt) isotope compositions of 13 iron meteorites...
Each year, about 2 kg of helium-3, a rare isotope of helium gas, escapes from Earth’s interior, mostly along the mid-ocean ridge system. Helium-3 is...
A team of astrobiologists from NASA’s Goddard Space Flight Center and the Carnegie Institution for Science has found a wide diversity of amino acids...
A type of meteorite called an enstatite chondrite has similar isotopic composition to terrestrial rocks and thus may be representative of the material...
In a paper published in the Astrophysical Journal Letters, Harvard University astrophysicists Avi Loeb and Amir Siraj show that an equal-mass stellar companion...
A research team led by Harvard University scientist Julie McGeoch has found a never-before-seen protein inside a meteorite called Acfer 086.
A sample of...
Scientists from Washington University, St. Louis, Caltech and the University of Chicago have found presolar grains — tiny bits of solid interstellar...
A team of researchers from the United States, Switzerland and Australia has found 4.6 to 7-billion-year-old presolar grains of silicon carbide (SiC) in...
An international team of scientists from the UK and Japan has found ‘fossilized asteroidal ice’ and pristine dust materials in a 4.6-billion-year-old...
According to new research, a nearby binary neutron-star merger gave birth to 0.3% of the Earth’s heaviest elements, including gold, platinum and uranium;...
A team of planetary scientists at the Australian National University found that our planet is made of the same elements as the Sun but has less of the...
The gas giant Jupiter is not only the most massive planet in our Solar System, but it’s also the oldest, according to an international team of planetary...
