Pic courtesy: Claire Diperna On a quiet afternoon in University Park, Pennsylvania, aerospace engineering student Divya Tyagi (22) sat buried in equations that had defeated generations of aerodynamicists. The puzzle, first posed more than a century ago by British pioneer Hermann Glauert, was central to understanding how wind turbines extract energy from the wind. What…

People with severe vision loss have been able to read again, thanks to a tiny wireless chip implanted in one of their eyes and a pair of hightech glasses.Age-related macular degeneration (AMD) is a common condition that affects the middle part of someone’s vision, often worsening over time. Its exact cause is unknown, but it…

Loeb said Christmas should bring clarity on whether 3I/ATLAS’s million-kilometre, ruler-straight jets come from natural ice fragments or technological probes As NASA insists the newly released images of interstellar visitor 3I/ATLAS confirm it is nothing more than a comet, Harvard astrophysicist Avi Loeb is arguing the opposite, that the most intriguing clues are only now…

A new Amazon Prime documentary has ignited fresh controversy in the UFO disclosure debate, alleging that three unidentified craft touched down at a New Mexico air base in 1964 and that former US President George H.W. Bush was privately informed about the extraordinary encounter decades later. Documentary revives claim of alien encounter at US Air…

Satellite navigation was once the quiet, invisible backbone of modern warfare. For decades, GPS gave the US military a decisive edge: precision strikes, coordinated operations and near-flawless navigation across land, sea and air. But the world has changed. On modern battlefields from Ukraine to the South China Sea, GPS has become unreliable and dangerously easy…

The latest nighttime photograph shared by the International Space Station offers a striking view of how human activity shapes the Earth after dark. The image highlights cities across Asia and South America that stand out because of their dense networks of artificial light. Delhi appears especially radiant, its interconnected roads and neighbourhoods forming vivid patterns…

A new set of deep-space images has reignited one of the strangest scientific arguments of 2025. The photos show sideways jet-like lines shooting out from the interstellar object 3I/ATLAS. Their geometry is so unusual that Harvard astrophysicist Avi Loeb says they may not be natural at all.Some astronomers insist the object is simply a weird…

Earth’s magnetic field acts like a protective cocoon, shielding the planet from harmful charged particles racing in from the Sun and deep space. But over the South Atlantic, that shield has developed an unusually weak patch known as the South Atlantic Anomaly. Recent observations show that this anomaly is not only expanding but also shifting,…

The early universe was once thought to be a quiet place where young galaxies grew slowly, gathered dust gradually and took long periods to form stars. New observations, however, show a much more active picture. One recently identified galaxy, located around 600 million years after the Big Bang, displays levels of warmth, brightness and star-forming…

Nasa released the images of Comet 3I/ATLAS on Wednesday, an interstellar object that briefly disappeared from public view, fuelling online speculation about alien technology. Multiple Nasa spacecraft near Mars had photographed the comet, but the images remained under wraps as the US government entered a 43-day shutdown.Senior officials have now dismissed all rumours, stressing that…
