The Moon was born when Earth’s sister planet died in a violent collision: Scientists reveal tragic origin

New research suggests Earth's Moon formed from the catastrophic collision of our planet with its "sister" planet, Theia, born nearby. This "sibling" planet theory, supported by iron isotope evidence, explains the Moon's composition and Earth's stable tilt. The Moon is now seen as the last remnant of a lost world, offering insights into planetary formation.

What NASA’s second CHAPEA mission reveals about human survival beyond Earth

What NASA’s second CHAPEA mission reveals about human survival beyond Earth

Four volunteers are spending a year in NASA's 3D-printed Mars habitat, simulating life on the Red Planet. This mission, CHAPEA, tests how isolation, limited resources, and confined spaces affect human health and teamwork. Researchers are gathering crucial data on sleep, stress, and problem-solving to make future Mars missions safer and more achievable.

Mysterious structures under the Pacific: What scientists found beneath the ocean floor could reshape Earth's history

Mysterious structures under the Pacific: What scientists found beneath the ocean floor could reshape Earth's history

Scientists have uncovered massive, dense rock structures deep beneath the western Pacific, challenging long-held theories about Earth's mantle. Advanced seismic imaging reveals these anomalies, which don't fit current models of subducting tectonic plates. Their existence suggests a more complex and ancient Earth interior than previously understood, prompting a re-evaluation of geological processes.

Why an ancient underwater volcano in Canada is covered in nearly a million giant skate eggs

An active underwater volcano off Canada's coast has revealed a vibrant deep-sea habitat, teeming with hundreds of thousands of Pacific white skate eggs. This geothermally active seamount provides a warm, mineral-rich environment, accelerating embryonic development and creating a crucial nursery. Researchers are studying this unique interaction between volcanic heat and reproduction, highlighting its importance for deep-sea life.

Saturn’s rings vanished in 2025: The rare cosmic alignment that stunned astronomers and skywatchers

Saturn’s rings vanished in 2025: The rare cosmic alignment that stunned astronomers and skywatchers

Saturn stunned skywatchers on 23 November when its iconic rings seemed to vanish, leaving the planet looking strangely bare. Astronomers confirmed nothing was wrong. Earth had passed directly through the ring plane, making the vast icy bands appear edge-on and nearly invisible. This rare alignment, occurring every 13 to 15 years, created a dramatic but temporary celestial illusion.
