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…

Every so often, physics delivers a discovery that feels as if it has stepped straight out of science fiction. The latest breakthrough is exactly that. Scientists have revealed a new kind of time crystal, an exotic phase of matter that repeats its structure not only in space but in time. Unlike ordinary crystals such as…

BENGALURU: Scientists at Isro’s Physical Research Laboratory (PRL) have captured new images and spectra of the interstellar comet 3I/ATLAS as it moves out of the inner Solar system after its recent perihelion passage.Using PRL’s 1.2m telescope at Mount Abu, researchers observed the comet between Nov 12 and 15. The images show a near-circular coma, the…

Long before telescopes, radio signals, or Harvard professors with strong views on aliens, early Homo sapiens stared at the sky and wondered whether someone out there existed and understood the world the way we did. As humans wandered across continents in search of new lands, they carried a parallel fantasy — that the universe, too,…
