There’s something beautifully democratic about a supermoon. No tickets, no telescopes, no Elon Musk subscriptions required. Just step outside, tilt your head, and for one night, the sky rewards you for remembering you’re on a spinning rock.This November, Earth gets its closest lunar rendezvous of the year — the supermoon of November 5–6, 2025, when…

If you ever wanted a courtroom drama where the jury consists of paleontologists, the defendant is a fossil, and the expert witness is a CT scanner, then welcome to the greatest dino trial since Jurassic Park made velociraptors the size of Great Danes. The 40-year mystery of the “tiny tyrant” has finally reached a verdict.For…

The year is 1838. A young German real estate agent, Thomas Hutter, is tasked with traveling to far-off Transylvania to meet the mysterious Count Orlok regarding a house for sale.

Move over, Crayola, the Neanderthals were colouring outside the lines long before we were. Archaeologists led by Francesco d’Errico from the University of Bordeaux, along with an international team of researchers, have unearthed what might be the world’s oldest “crayon” — a 42,000-year-old yellow ochre stick found at Neanderthal sites in Crimea and Ukraine. The…

The year 2025 has brought us a rare cosmic visitor. 3I/ATLAS is only the third confirmed interstellar object ever detected — after ʻOumuamua in 2017 and Comet Borisov in 2019. Discovered on July 1, 2025, by the ATLAS survey telescope, this object is on a hyperbolic orbit, meaning it came in from outside our Sun’s…

Source: CCOR-1 instrument Interstellar comet 3I/ATLAS has captivated astronomers as it makes a rare and dramatic passage around the Sun. Although currently hidden from Earth’s view, NASAand international spacecraft have continued to track its journey, revealing that the comet brightened rapidly as it neared perihelion, its closest approach to the Sun, on 30 October 2025….

Elon Musk’s SpaceX has responded to growing concerns from NASA about the readiness of its Starship rocket for lunar missions. On 30 October 2025, the company announced that it had submitted a “simplified” mission plan to NASA aimed at sending humans to the Moon safely and efficiently. In a detailed blog post, SpaceX explained that…

In recent years, the rising congestion in Earth’s orbit has become one of the most pressing challenges facing space-faring nations. Thousands of inactive satellites, rocket fragments, and collision-generated particles now orbit the planet at high velocity, posing significant risks to operational spacecraft and the infrastructure that supports communications, navigation, and climate observation. With the global…

Comet 3I/ATLAS has fascinated astronomers and space enthusiasts worldwide as it makes its rare journey through our solar system. Recognised as the third known interstellar object, 3I/ATLAS originates from beyond our Sun, offering a unique glimpse of a visitor from another star system. Unlike typical comets that orbit the Sun, it follows a hyperbolic trajectory,…

Astronomers have discovered an ancient, ice-rich interstellar object called 3I/ATLAS, which could transform our understanding of how comets form and evolve. Detected by the University of Oxford’s research team, this mysterious object is believed to have originated far beyond our solar system, possibly more than seven billion years ago. Its immense age suggests it predates…

Beneath the familiar crust we walk on lies a vast, unseen world teeming with microscopic life. For decades, scientists assumed the deep Earth was too hot, dark, and nutrient-poor to sustain anything alive. Yet new discoveries are forcing us to rethink the boundaries of biology. These strange microbes are thriving kilometres underground and may even…

“With great silk comes great responsibility.” — probably not what Peter Parker’s uncle had in mind, but it fits. Because if Spider-Man ever retired to the Tuscan countryside, he’d find fierce competition in the orb-weaving arachnids of Sardinia. These eight-legged engineers aren’t just catching flies — they’re busy redecorating their homes like they’re auditioning for…

Source: Oregon State University In a groundbreaking discovery, a team of US scientists has unearthed the oldest directly dated ice and air ever found on Earth, buried deep within the Allan Hills region of East Antarctica. The ice, estimated to be six million years old, preserves tiny air bubbles that serve as time capsules, offering…

In a remarkable palaeontological breakthrough, scientists have uncovered two mummified duck-billed dinosaur fossils in the Wyoming badlands, marking the first-ever discovery of hooves in dinosaurs. These exceptionally preserved specimens, identified as Edmontosaurus annectens, offer an unprecedented look into the anatomy and lifestyle of one of the last great herbivores of the Cretaceous period. The find…

A newly discovered interstellar comet named 3I/ATLAS is making its way through our solar system, capturing global scientific attention. Although it poses no danger to Earth, this rare celestial visitor offers a remarkable opportunity to study material from beyond our solar neighbourhood. NASA and its international partners have launched a coordinated observation campaign to examine…
