In 2024, NASA's Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, ...
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere ...
Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection of the system, designated ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation ...
Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending ...
