Intricate structures within the Cat’s Head Nebula are illuminated in this mid-infrared view from NASA’s James Webb Space Telescope released on Oct. 29, 2026. The distinctive “cat’s head” shape of the nebula was likely sculpted over time by the intense ultraviolet radiation and winds from massive stars in the Carina Nebula. As this stellar feedback […]

The aircraft reportedly took off from the Hindu pilgrimage site of Badrinath on Friday afternoon before losing contact.
Scientists may have solved a 66-million-year-old mystery: how crocodiles survived the asteroid that wiped out the dinosaurs. A sweeping analysis of fossils and ancient climates suggests that their preference for warm environments placed them in tropical refuges that remained habitable even after the catastrophic impact.
A computer scientist has achieved a breakthrough in a nearly 25-year-old problem involving how computers calculate distances across enormous networks. The new algorithm delivers more reliable estimates for closely connected points without sacrificing speed, overcoming a longstanding limitation of earlier methods. Its secret lies in a smarter way of sampling network connections at multiple scales.
Twin Travelers In 1977, NASA launched twin spacecraft Voyager 1 and 2, taking advantage of a once-every-175-year planetary alignment of the four largest planets in our solar system: Jupiter, Saturn, Uranus, and Neptune. Using six gravity assists between them, this Grand Tour gave us up-close views of the gas and ice giants, including several moons. […]
