A medieval seal with a blood-red gemstone that was discovered in the U.K. is hiding an ancient secret, researchers have found. A metal detectorist discovered the medieval seal in Gosfield, in the eastern county of Essex, in the fall of 2024. But a recent analysis of the seal by experts with the U.K.’s Portable Antiquities

Tonight, Sunday 1 February, the full Moon will rise in the eastern sky, kicking off the month with a beautiful lunar spectacle. This is the Snow Moon, which is the name given to February’s full Moon. It rises in the east, tracks across the sky to the south, then will set in the west around
NASA’s Artemis program is preparing for an incredible journey that could reshape humanity’s presence on the Moon. As part of this groundbreaking mission, the Artemis 2 crew will wear specially designed spacesuits that will help protect them during their voyage around the Moon. These suits are not just pieces of clothing; they represent a key
Refresh 2026-02-01T14:17:45.435Z Countdown begins for Artemis 2 fueling test (Image credit: NASA/Joel Kowsky) Good morning, space fans! Happy Sunday. NASA officially began the countdown last night for its upcomiong Artemis 2 fueling test as it works toward a Feb. 8 launch target for the first astronaut trip around the moon in over 50 years. The
NASA’s Artemis II mission is set to launch as early as February 6, putting human spaceflight to the moon back in the spotlight after a 50-plus year hiatus which may inspire future filmmakers to explore the possibilities of space travel in their own work. In celebration of our IRL return to the drama and wonder
Scientists unveiled the most detailed map ever created of Antarctica’s hidden landscape beneath miles of ice, revealing thousands of previously unknown features that could transform predictions about sea level rise. What’s happening? Researchers combined satellite observations with physics modeling to chart Antarctica’s subglacial topography in unprecedented detail. Their findings, published in Science, identified tens of
Originally discovered in 1986, these microscopic structures, called vaults, have puzzled researchers for decades. Their function remained largely unknown, until now. A team led by molecular biologist Fei Chen from MIT and Harvard has successfully reprogrammed vaults to collect messenger RNA (mRNA), offering a new way to chronicle a cell’s past activity without destroying it
Scientists have discovered the largest organic molecule containing sulfur — a key ingredient for life — ever identified in interstellar space. The researchers call the discovery a “missing link” in scientists’ understanding of the cosmic origins of life’s chemistry. Sulfur is the 10th most abundant element in the universe and a critical component of amino
Anthropic’s Claude machine learning model has boldly planned what no Claude has planned before – a path across Mars for NASA’s Perseverance rover. Perseverance traveled about 400 meters on the Martian surface last month based on an AI-generated path. It did so with the blessing of engineers at NASA’s Jet Propulsion Laboratory (JPL), who decided
