A new study reveals that ancient Homo sapiens possessed a unique adaptability, thriving in diverse and challenging environments across Africa before their major dispersal around 50,000 years ago. This "ecological flexibility," as termed by researcher Emily Hallett, enabled them to inhabit rainforests, deserts, and more.

European Space Agency's Proba-3 mission has successfully created artificial solar eclipses using two satellites flying in precise formation. This innovative approach allows scientists to study the sun's corona for extended periods, achieving up to six hours of totality per eclipse. The mission promises a wealth of data, potentially revolutionizing our understanding of the sun's behavior and its impact on Earth.
NASA has postponed the Axiom-4 mission to the ISS due to ongoing air leak investigations in the Russian segment, in collaboration with Roscosmos. Recent repairs showed initial success, but a new pressure anomaly requires further assessment. The delay impacts Axiom Space's mission, intended to transport four private astronauts via SpaceX, while prioritizing safety and structural integrity.
NASA's GOLD mission made a surprising discovery. It observed X-shaped patterns in the ionosphere. These patterns occurred even during calm space weather. Previously, scientists thought they only happened during solar storms. The finding changes our understanding of the upper atmosphere. It also affects satellite communications and GPS signals. Scientists are now investigating the causes of these unexpected X-shapes.
International Space Station astronauts celebrated with 'space sushi'. Jonny Kim shared the crew's creative meal on social media. They used rice, spam, fish, gochujang, and wasabi. Limited supplies didn't stop them. Astronauts taped surfaces to keep food from floating. The meal boosted morale and fostered connection. Social media users admired their resourcefulness and ingenuity.
Scientists have achieved a groundbreaking feat by detecting a 13-billion-year-old microwave signal from the Cosmic Dawn using Earth-based telescopes in Chile. This discovery, made by the CLASS project, provides unprecedented insights into the early universe and the formation of the first stars and galaxies.
SpaceX successfully launched 26 Starlink satellites from California's Vandenberg Space Force Base on Monday. The Falcon 9 rocket, making its third flight, deployed the satellites into low Earth orbit. The rocket's first stage landed on the drone ship in the Pacific Ocean. This launch follows a similar Starlink deployment from Florida, which completed the first-generation Starlink direct-to-cell satellite constellation.
A 60-meter asteroid, 2024 YR4, has a 4.3% chance of hitting the Moon on December 22, 2032. NASA warns the impact could eject lunar debris towards Earth, endangering satellites and future lunar missions. Scientists estimate a significant portion of this debris could damage or disable satellites, potentially causing widespread communication and GPS failures.
The European Space Agency's Proba-3 mission has achieved a groundbreaking feat by capturing the first images of the Sun's corona using an artificial solar eclipse created in space. Two spacecraft flew in precise formation, with one blocking the Sun's glare, enabling the other to image the corona in unprecedented detail.
A rare black iceberg, spotted off Labrador, Canada, has captivated scientists and social media users. The dark coloration is likely due to sediment incorporated into the ice as a glacier moved over land. As the iceberg melted, these sediment-rich layers were revealed, creating a striking visual phenomenon and a scientific puzzle.
SpaceX successfully launched 26 more Starlink satellites into low Earth orbit from California, expanding its global broadband network. The Falcon 9 rocket, on its third flight, deployed the satellites as part of the Group 15-9 mission. The booster landed successfully on a droneship, ensuring its reuse for future launches, supporting SpaceX's goal of cost-effective space access.
