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…

There are moments in space exploration when a single picture forces scientists to pause, rethink and question everything they know. That is precisely what happened when NASA’s Perseverance rover captured a strange boulder sitting alone in the Jezero Crater region. Its texture, colour and placement immediately stood out. This was not the sort of rock…

For decades, the disappearance of Neanderthals has been explained through dramatic stories of sudden extinction. Some theories suggested they were hunted, others that they starved when climates shifted, and a few even claimed modern humans wiped them out. But recent research paints a quieter and far more fascinating picture. Instead of a sharp ending, Neanderthals…

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…

NASA has released a set of extraordinary radar images showing an asteroid spinning so fast that it has forced scientists to rethink long-held assumptions about small bodies in space. The asteroid, known as 2025 OW, is tiny compared to the large space rocks we normally hear about, yet its behaviour is anything but ordinary. Detected…

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…
