ScienceNASA has awarded three U.S. firms contracts totaling nearly $600 million to deliver scientific cargo to the Moon, marking a calculated push to establish a lunar surface base. These uncrewed missions aim to deploy robotic infrastructure, including power grids and habitats, before human explorers arrive at the lunar south pole.
ScienceA fossil unearthed on James Ross Island in 1985 remained misidentified in a Cambridge storage drawer for nearly forty years. Only recently did a team of paleontologists, led by Mark Evans, recognize the specimen not as a generic reptile bone, but as the first dinosaur discovery ever recorded in Antarctica.
ScienceA robotic spacecraft will soon attempt to capture and boost the sinking Neil Gehrels Swift Observatory, marking the first time such an orbital rescue has been attempted. Facing rapid altitude loss due to intense solar activity, the two-decade-old telescope is being targeted for a life-extending maneuver to prevent atmospheric reentry.
ScienceMount Erebus, the southernmost active volcano on Earth, is defying geological norms by venting microscopic crystals of pure gold into the air. Located on Ross Island, this remote peak releases roughly 80 grams of the precious metal daily, amounting to an annual value exceeding $2 million as it drifts across Antarctic ice.
ScienceA high-energy ghost particle detected beneath the Antarctic ice has been traced to a distant star-forming galaxy 11 billion light-years away. By catching the galaxy, nicknamed Shadow Blaster, in a brief moment of brightness, researchers have identified a rare celestial origin for these elusive, near-massless cosmic messengers.
ScienceWith its altitude plummeting toward a point of no return, the Neil Gehrels Swift Observatory faces a robotic rescue mission designed to defy its own design. NASA has contracted Arizona startup Katalyst Space Technologies to intercept the aging telescope, attempting an unprecedented mid-orbit boost for a craft never intended for service.
ScienceLocated 27,000 light-years away in the constellation Sagittarius, NGC 6723—known as the Chandelier Cluster—shines with the light of thousands of tightly bound stars. NASA’s Hubble Space Telescope recently captured this dense stellar collection, offering a rare glimpse into the primordial architecture of our galaxy.
ScienceA tiny blue-green speck against the crimson dust of Jezero Crater, NASA’s Perseverance rover was caught by an orbital camera just hours before crossing a 26.2-mile threshold. This milestone marks the end of a grueling five-year trek across Martian bedrock, shattering the speed records set by its predecessors.
ScienceMost people watch the sun dip below the horizon for minutes at a time, but for those in low Earth orbit, the event is a frantic, eight-second flash. NASA astronaut Don Pettit recently shared a timelapse from the International Space Station, illustrating the jarring speed of day turning to night.
Twelve million light-years from Earth, the Cigar Galaxy is undergoing a violent transformation. NASA’s James Webb Space Telescope has pierced through dense, opaque clouds of cosmic dust to map the chaotic star formation within Messier 82, exposing the complex, energetic structures previously hidden from the Hubble Space Telescope’s view.
ScienceA ticklish experiment involving 13 captive great apes and four young children reveals that the rhythmic structure of laughter may be an ancient biological inheritance. New findings suggest humans and their closest primate relatives have shared a consistent pattern of vocalized joy for approximately 15 million years.
ScienceFloating 250 miles above the Earth, NASA astronaut Jessica Meir recently turned her lens toward the Pacific Northwest, documenting the raw intensity of a storm system. Her latest images from the International Space Station reveal the stark contrast between the serene, textured cloud layers and the ominous, towering structures of active thunderclouds.
ScienceThe Perseverance rover has identified complex macromolecular carbon within mudstones at the Bright Angel outcrop, a site inside the ancient Neretva Vallis river channel. While these organic molecules represent the building blocks of life, researchers caution that they may also originate from non-biological geological processes.
ScienceOrbiting a star 1,110 light-years away in the constellation Volans, two newly identified exoplanets defy conventional celestial physics. Despite sharing the immense physical dimensions of Jupiter, these bodies possess such remarkably low density that researchers liken their consistency to a fresh, airy blob of shaving foam.
ScienceDeep within the Calakmul Biosphere Reserve, researchers have uncovered Ocomtún—a sprawling, untouched Maya urban center that remained hidden for over a millennium. Named for the rugged terrain that kept it isolated, the site offers a rare, pristine look at the complex architecture and water systems of the Late Classic period.
