Astronomers continue to expand humanity’s cosmic horizons. NASA’s James Webb Space Telescope (JWST) has confirmed and built upon the Hubble Space Telescope’s groundbreaking discovery of Earendel, the most distant star ever observed. This extraordinary star shines just one billion years after the Big Bang, offering a rare glimpse into the early universe. Studying Earendel provides…

On Sunday, September 28, 2025, SpaceX launched 28 Starlink satellites into low Earth orbit from Vandenberg Space Force Base in Southern California. The Falcon 9 rocket’s ascent lit up the evening sky, creating a striking spectacle for viewers across the region. Spectators captured dazzling images and videos, sharing them widely as the event quickly gained…

BENGALURU: Spacetech startup Agnikul Cosmos has announced plans to build fully reusable rockets, committing to ensure that no part of its vehicles is expended or left behind. The declaration came at the International Astronautical Congress (IAC) 2025 in Sydney, which is themed “Sustainable Space: Resilient Earth.”The Chennai-based start-up said its reusability push builds on a…

For decades, scientists have debated which animals first appeared on Earth and set the stage for the evolution of complex life. A recent study by MIT geochemists offers compelling evidence that the earliest animals were not dinosaurs or the unusual creatures of the Cambrian explosion, but ancient ancestors of today’s sea sponges. These soft-bodied, ocean-dwelling…

Expired medication may seem harmless, but taking it can pose serious health risks. Medications lose potency over time, and some may even become contaminated, particularly liquid forms like cough syrups or eye drops. Using drugs past their expiration date can reduce effectiveness, worsen symptoms, or trigger unexpected side effects, especially for chronic conditions or infections….

Source: National Park Service Deep beneath the rolling hills of Kentucky, in the extensive labyrinth of Mammoth Cave National Park, scientists have made an extraordinary discovery. Fossilised remains of two previously unknown prehistoric shark species, Troglocladodus trimblei and Glikmanius careforum, were uncovered, preserved in limestone for over 325 million years. These ancient predators provide a…

In the deserts of southern Australia, scientists have been captivated by tiny, shimmering glass fragments scattered across the vast, arid terrain. Formed under extreme conditions of heat and pressure, these delicate shards have puzzled researchers for decades, as they are neither volcanic in origin nor human-made. Recent geochemical and isotopic studies reveal that these fragments…

As autumn spreads its golden charm across fields and forests, the crisp air carries whispers of change, and the night sky readies itself for one of its most captivating spectacles—the Harvest Moon. Unlike other full moons, the Harvest Moon holds a unique place in both tradition and astronomy, rising closest to the September equinox. Its…

The night sky has long fascinated humanity, offering both beauty and mystery. Occasionally, it delivers something far more extraordinary—like an asteroid making its way toward Earth. On September 30, 2025, NASA confirmed that asteroid 2025 SA3, a space rock measuring about 54 feet (16.5 meters) in diameter, is traveling on a trajectory that will bring…

The 3I/ATLAS interstellar object has sparked worldwide scientific interest because of its extraordinary size, mass, and unusual trajectory. Recent studies reveal that it is far larger and more massive than earlier estimates, making it one of the most remarkable interstellar visitors observed to date. Detected by NASA, 3I/ATLAS is being carefully monitored by astronomers to…
