Most people think of data transfer as instantaneous, but there is a hard physical limit of course – the speed of light. Grace Hopper used an 11.8-inch wire to communicate this "nanosecond" constraint loud and clear. If you're interested in the details, I’ve put together a breakdown of the math explaining why computers inevitably had to get smaller to get faster. submitted by /u/tucna |

Back to Article List Everyone can watch a small moon skim Saturn’s northern pole, while advanced imagers may catch its shadow on the cloud tops. Tenth-magnitude Dione passes north of Saturn twice this month, accompanied by its shadow. The latter can only be detected via imaging. Also shown are several fellow moons: Rhea and Tethys…

A Proving Ground In an interview with Face the Nation, Isaacman said that humanity was “lucky” to be “gifted a…
Three years before the skyscraper-size asteroid Apophis makes its very close (but safe) flyby of Earth, scientists have already begun charting exactly when and where billions of people can watch it sweep across the sky. Speaking at an “Apophis T-3 Years” workshop held earlier this month at the University of Padua in Italy, retired cartographer…
In summer 2026, sixteen stadiums across North America hosted matches as part of the FIFA World Cup. Over the years, astronauts aboard the International Space Station have captured a top-down view of the infrastructure, landscapes, and ecosystems surrounding many of these venues. Six of the matches were played at the San Francisco Bay Area Stadium,…
Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope. NASA released this image to celebrate the United States’ 250th anniversary, as the agency carries forward America’s legacy of exploration. Located in the outer halo of our Milky Way galaxy, globular…
