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.

SpaceX's Starship prototype faced another setback. A static fire test resulted in an explosion. The incident raises concerns about the rocket's reliability. This test follows previous failures, including a destroyed Super Heavy booster. Starship is crucial for missions to the Moon and Mars. SpaceX insists that these tests provide valuable data. The company aims to reduce space travel costs.
Former NASA agent Joseph Gutheinz dismisses UFO sightings as alien visits, citing vast interstellar distances. He suggests these sightings are likely advanced drones, secret military tech, or government cover-ups to conceal projects from adversaries. Gutheinz urges rational thinking, demanding evidence and suggesting a focus on earthly explanations rather than extraterrestrial speculation.
The summer solstice marks the longest day in the Northern Hemisphere and the start of astronomical summer, while the Southern Hemisphere experiences its shortest day and the beginning of winter. Solstices occur due to Earth's tilt, causing unequal distribution of sunlight. Equinoxes, conversely, bring equal day and night, with the sun directly overhead at the equator.
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.
Marine megafauna, including whales and sharks, face increasing threats from human activities, impacting ocean ecosystems. A recent study by WHOI and ANU tracked these species to identify critical areas for conservation. The research emphasizes the need for expanded marine protected areas and mitigation strategies to alleviate human pressure and ensure the survival of these vital ocean giants.

Astronomers have observed thick, mineral-rich clouds, potentially containing iron, enveloping the young exoplanet YSES-1b, leading to the possibility of iron rain. The YSES-1 system, only a million years old, features two gas giants, offering a unique opportunity to study planet formation. Researchers are intrigued by the persistent dust disk around YSES-1b, challenging existing planet formation theories.
A recent study of 514-million-year-old archaeocyathid reefs in Nevada reveals that early reefs didn't consistently boost biodiversity like modern coral reefs. Researchers found inconsistent patterns of marine life around these ancient reefs, largely dependent on localized conditions. This discovery challenges assumptions about reef ecosystems and offers insights into the evolution of marine systems.
In a groundbreaking discovery, researchers captured the first-ever live footage of a rare blood-red Antarctic gonate squid at a depth of 7,060 feet. Identified by its distinctive tentacle hooks, this elusive creature was observed in its natural bathypelagic habitat. This sighting, deemed "mission-critical," provides invaluable insights into the behavior and ecology of this deep-sea predator.
