Sleep is often seen as a universal human need. But research suggests that women not only sleep differently from men but also need more of it.DW spoke with women in various regions of the world, who all shared stories of needing more rest than they were getting and told us of the toll of what’s…

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…

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,…

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….

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…

The interstellar object 3I/ATLAS has captured global attention not only for its unusual trajectory through space but also for a mysterious pulse signal reportedly linked to it. Scientists are investigating this strange sequence, which appears to follow the Fibonacci pattern, which is a mathematical sequence commonly found in DNA, plants, and galaxies. Detected at a…
