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.

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.

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.

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 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.

Astronomers have discovered a new, previously unnoticed concentration of icy bodies in the Kuiper Belt, dubbed the 'inner kernel.' This finding, made possible by advanced clustering algorithms, suggests the cold classical belt is more layered than previously thought. It offers crucial new insights into Neptune's complex migration and the early evolution of our Solar System, challenging existing models.

Antarctica's ozone hole is showing significant recovery, appearing smaller and breaking up earlier this year. Scientists attribute this positive trend to global efforts under the Montreal Protocol, which has reduced ozone-depleting chemicals. While weather plays a role, the long-term outlook for the ozone layer's full recovery by the late 2060s remains promising.

NASA has discovered CWISE J1249, a mysterious red celestial object moving at over one million miles per hour through the Milky Way. This object, with its extremely low mass and unique infrared signature, challenges current theories of stellar and planetary formation. Scientists are investigating if it's a supernova remnant or an ejected planet, as its characteristics defy conventional classification.

The Elephant’s Foot, a solidified mass formed beneath Chernobyl’s Reactor Four in 1986, once emitted nearly 10,000 roentgens an hour, enough to kill within minutes. Created from molten fuel and debris, it weighs about two tonnes and remains dangerously radioactive. Even decades later, it stands as one of the most lethal legacies of the disaster and a lasting reminder of the risks of nuclear failure.

NASA’s new images of interstellar object 3I/ATLAS have done little to settle the debate. While the agency insists it is a harmless comet, Harvard astrophysicist Avi Loeb argues the data leaves key anomalies unexplained, especially the million-kilometre, ruler-straight features captured by amateur astronomers. Loeb says December’s close approach may finally reveal whether 3I/ATLAS is natural, or something engineered.

A new Amazon Prime documentary alleges three alien craft landed at a New Mexico air base in 1964, with former President George H.W. Bush reportedly informed of the encounter decades later. The film also details a secret government "Legacy Programme" for UFO retrieval, raising national security concerns about ongoing secrecy.

Modern warfare faces a critical challenge as GPS becomes unreliable due to jamming and spoofing. The Pentagon is exploring quantum sensors, like magnetometers, that use Earth's magnetic field for navigation. While promising, these technologies require detailed maps and face hurdles in battlefield conditions, pushing for hybrid solutions to ensure military autonomy.

The journey of growing food in space began with potatoes in the 1990s, proving tubers could form in microgravity. This foundational research paved the way for later successes, like red romaine lettuce harvested and eaten by astronauts on the ISS. These advancements highlight plant adaptation and the potential for self-sustaining food systems on future interplanetary missions.

The International Space Station captured a stunning image of Earth at night. Delhi's bright lights stand out, showcasing its growth. The city is compared to other luminous megacities like Singapore, Tokyo, and Sao Paulo. These images reveal urban development and population growth. Orbital views offer insights into future city expansion and energy use.

International students in the US are increasingly drawn to STEM disciplines, with a remarkable 57% opting for studies in science, technology, engineering, and math. This surge is fueled by the rising global need for expertise in fields such as computer science and AI, further supported by initiatives like OPT that grant valuable work opportunities post-graduation.

Earth's protective magnetic shield has a weak spot, the South Atlantic Anomaly, which is expanding and splitting. This anomaly, driven by changes in Earth's core, poses risks to satellites and spacecraft by increasing radiation exposure. NASA is enhancing monitoring as this dynamic region affects space technology and our understanding of Earth's interior.

Astronomers have discovered an unusually bright and warm galaxy, MACS0416_Y1, dating back to just 600 million years after the Big Bang. This early galaxy is forming stars at an astonishing rate, challenging previous beliefs about galactic evolution. Its intense infrared glow, powered by heated dust, suggests rapid development and efficient star formation in the nascent universe.
