Space is becoming a dangerous place due to more satellites. A new CRASH Clock shows a critical risk of collisions. Solar storms can disable satellites, leading to potential chain reactions. Scientists warn urgent action is needed to prevent a space disaster. The situation is dire, with less than three days' warning possible.

Jared Isaacman is now NASA's 15th administrator. The Senate approved him, paving the way for crucial missions. Isaacman will lead the Artemis program, aiming to land humans on the Moon again. He also plans for Mars exploration. His experience in private spaceflight is expected to boost collaboration. NASA faces challenges including budget cuts and personnel reduction.

Albert Einstein's dying wish for cremation and secret ash scattering was partially ignored. While his body was cremated, pathologist Thomas Harvey removed his brain and eyeballs. The eyes, given to his ophthalmologist, remain in a New York safe deposit box, their purpose unclear and their existence a quiet contradiction to Einstein's rejection of physical veneration.

Scientists studying one of the Pacific’s most active underwater volcanoes were stunned to find hammerhead and silky sharks living inside its crater. Footage captured near the Solomon Islands showed the animals swimming through hot, acidic water previously thought uninhabitable. Researchers say the discovery raises new questions about how marine life survives extreme environments and adapts to climate stress.

NASA is undertaking a vast observation effort for comet 3I/ATLAS. This interstellar visitor is being studied by multiple spacecraft and telescopes. Researchers aim to understand its composition and origin by comparing it with solar system comets. The comet will be closest to Earth on December 19, offering a viewing opportunity with telescopes.

La Niña returns to the Pacific after a brief neutral phase. This event, expected from September to December 2025, is considered weak. Its influence on global weather and climate patterns is being closely monitored. Changes in sea level, rainfall, and temperature are anticipated across continents. Researchers are tracking ocean temperatures and atmospheric circulation for disaster preparedness and climate outlooks.

Albert Einstein’s death in 1955 set off an extraordinary and ethically fraught afterlife for his brain, secretly removed by a hospital pathologist and kept for decades. Intended as a scientific quest, the episode instead became a prolonged saga of disputed consent, questionable research, and a specimen that wandered far from Einstein’s own wishes before finally reaching museums.

Recent research suggests that small, carbon-rich asteroids could be invaluable economic and scientific resources, offering water, organic materials, and precious minerals for space missions. These primitive bodies, acting as time capsules, hold the key to fueling future exploration and reducing Earth's resource dependency, despite current technical challenges in large-scale mining.

While Mars doesn't directly control Earth's climate, its gravity subtly influences our planet's orbit and tilt over vast timescales. These predictable orbital shifts, affecting sunlight distribution, have historically driven ice ages. Scientists emphasize this gravitational nudge is distinct from rapid, human-caused global warming, offering crucial context for understanding Earth's long-term climate history.
