The Elephants Foot of Chernobyl/ Stanford University If you were to stand near it for just thirty seconds, you might feel nothing at first, only to find yourself overwhelmed by dizziness and fatigue days later. At two minutes, your cells would begin breaking down. Four minutes could bring vomiting and fever. And if you lasted…

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 quest to grow food beyond Earth has fascinated scientists and space agencies for decades, not only as a matter of survival, but as a critical strategy to sustain life on long-duration missions and future interplanetary exploration. Although many imagine leafy greens in space, the first vegetable ever to take root in microgravity was the…

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…

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,…

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…

Interstellar comet 3I/ATLAS images to be released by NASA The comet 3I/ATLAS, the third interstellar object ever discovered, is currently passing through the inner solar system, and NASA is preparing to stream its most detailed images yet. Since its detection in July 2025, scientists have closely monitored its unusual chemical makeup, fast hyperbolic trajectory, and…

NASA is preparing to showcase new imagery of the interstellar comet 3I ATLAS, offering the public a closer look at one of the rarest visitors to our solar system. The comet, which was discovered by the ATLAS observatory earlier this year, is only the third confirmed object to enter our solar system from elsewhere in…

Most people imagine a world without cockroaches as a cleaner, calmer place. No sudden scurrying in the kitchen, no unwelcome surprises under the sink and no pests invading food storage. But although the idea sounds appealing at first, the reality is far more complicated. Cockroaches have survived for millions of years because they fill ecological…

Interstellar objects moving through the Solar System represent a rare but scientifically valuable population of visitors that originate beyond the Sun’s gravitational reach. Their potential to collide with Earth, although extremely low in absolute terms, has attracted renewed attention as astronomers refine models that predict their paths, entry points and likely impact characteristics. Advances in…

The Indian Space Research Organisation (ISRO) is gearing up for one of its most intensive periods of activity, with seven additional launches planned before the close of the current financial year. While India’s first human spaceflight is still scheduled for 2027, the organisation is pushing forward with rapid expansion across science, technology, and industry, according…
