A study published in Nature presents strong new evidence that a vast ocean once covered a significant portion of Mars. Researchers identified a large, flat geological formation resembling continental shelves on Earth, suggesting that liquid water remained stable on the planet for millions of years. The......
The behavior of gravity remains consistent with predictions made by Isaac Newton and Albert Einstein even across vast cosmic distances, according to a study published in Physical Review Letters. The findings come from the largest test of gravitational strength ever conducted and reinforce the prevailing......
The NASA James Webb Space Telescope has captured direct images of a massive exoplanet that appears to have formed like a planet rather than a star, reshaping assumptions about how large planets can grow. The findings, published in The Astrophysical Journal Letters, focus on 29 Cygni b, a gas giant with......
Researchers at University of Texas at Austin have engineered a compact CRISPR enzyme that fits inside viral delivery systems used in gene therapy, marking a step toward practical in vivo genome editing. The work, funded by the National Institutes of Health, was published in Nature Structural & Molecular......
Scientists have developed Geostationary Ocean Flow, or GOFLOW, a deep learning system that converts images from existing weather satellites into hourly ocean current maps. This approach captures fast-moving small-scale eddies previously hard to observe. The method appears in a study published Monday......
Six days after capturing a crescent view of Earth slipping behind the Moon, the crew of Artemis II has returned to Earth as their image, known as “Earthset,” gains global attention and comparisons to the historic “Earthrise” photograph from Apollo 8 in 1968. The photograph was......
A long-period comet from the outer reaches of the solar system is now visible before dawn, offering a limited viewing window for observers in the Northern Hemisphere. The comet, C/2025 R3 (Pan-STARRS), was spotted with the naked eye on April 11 at an estimated magnitude of 5.1. It was first discovered......
Chinese scientists have developed the first crystal capable of generating the ultraviolet light required to power thorium-based nuclear clocks, marking a key step toward navigation systems that can operate without GPS. The material, a fluoroborate compound created by a team led by Pan Shilie at the......
The four astronauts of NASA’s Artemis II mission—three Americans and one Canadian—have safely returned to Earth after completing a historic test flight around the Moon, marking a major milestone in the renewed era of lunar exploration. The crew, including Commander Reid Wiseman, Christina......
When people picture a familiar face or recall a place, the brain activates many of the same neurons involved in seeing it. A study published on April 9 in Science by researchers at Cedars-Sinai provides detailed evidence at the single-neuron level that visual perception and mental imagery rely on a shared......
The NASA Artemis II mission encountered repeated malfunctions in its onboard toilet system as the crew returns from a historic lunar flyby, highlighting ongoing technical challenges aboard the Orion spacecraft. The issues began shortly after launch from the Kennedy Space Center on April 1, when astronauts......
The four astronauts aboard NASA's Artemis II mission experienced a total solar eclipse Monday evening as their Orion spacecraft rounded the far side of the Moon, capping a day of historic milestones on the first crewed lunar voyage in more than half a century. The eclipse, visible only from the......
The four astronauts aboard NASA's Artemis II mission are swinging around the Moon on Monday in humanity's first crewed lunar voyage in more than 53 years, with the crew on course to shatter a distance record that has stood since 1970. Commander Reid Wiseman, pilot Victor Glover, mission specialist......
