Binoculars mean the difference between seeing a little gray bird and identifying a titmouse, cheering a home run and seeing the epic catch, or realizing that the 10-point buck is actually a doe standing in front of dead branches. Whether you're scouting terrain, watching birds in your backyard, stargazing, or getting season tickets at Fenway, binoculars bring the world closer.

Tuesday Telescope: A new champion enters the ring

arstechnica.com Unknown 2026-02-24 15:00:09

Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder. After a decade of construction a large new reflecting telescope publicly released its first images on Monday, and they are nothing short of

Trump's Attack May Instead Spur Iran to Speedrun a Nuclear Weapon It Wasn't Building Previously

futurism.com Unknown 2026-02-25 02:26:50

Trump's Attack May Instead Spur Iran to Speedrun a Nuclear Weapon It Wasn't Building Previously An extremely ironic outcome. Bomb Squad President Donald Trump is trying to derail Iran's nuclear weapons ambitions by bombing its known nuclear research facilities — but it turns out that's easier said than done. US officials have trumpeted that the recent strikes obliterated Iran's nuclear enrichment sites, but satellite images have cast doubt on that claim. And in any case, Trump's bombing camp

The National Science Foundation just shared the first images captured by the Vera C. Rubin Observatory, a sample of the footage it'll capture as part of a planned decade-long survey that's starting later in 2025. The project, dubbed the "Legacy Survey of Time and Space" is predicted to lead to the discovery of "millions of new asteroids within the first two years" the survey is running.

Perched atop the Cerro Pachón mountain in Chile, 8,684 feet high in the Atacama Desert, where the dry air creates some of the best conditions in the world to view the night sky, a new telescope unlike anything built before has begun its survey of the cosmos. The Vera C. Rubin Observatory, named for the astronomer who discovered evidence of dark matter in 1978, is expected to reveal some 20 billion galaxies, 17 billion stars in the Milky Way, 10 million supernovas, and millions of smaller objects

Today, that promise has become a staggeringly beautiful reality. Rubin’s view of the universe is unlike any that preceded it—an expansive vision of the night sky replete with detail, including hazy envelopes of matter coursing around galaxies and star-paved bridges arching between them. “These images are truly stunning,” says Pedro Bernardinelli, an astronomer at the University of Washington. During its brief perusal of the night sky, Rubin even managed to spy more than 2,000 never-before-seen

We’ve had a Denisovan skull since the 1930s—only nobody knew

news.ycombinator.com Unknown 2026-02-23 20:42:58

A 146,000-year-old skull from Harbin, China, belongs to a Denisovan, according to a recent study of proteins preserved inside the ancient bone. The paleoanthropologists who studied the Harbin skull in 2021 declared it a new (to us) species, Homo longi. But the Harbin skull still contains enough of its original proteins to tell a different story: A few of them matched specific proteins from Denisovan bones and teeth, as encoded in Denisovan DNA. So Homo longi was a Denisovan all along, and thank

Cannabis scientists are trying to find a predictable, reliable product (2020)

I hadn't for these reasons. It is a lot of work. What I have to say is obvious to logicians, and they would consider the detour into programming to only be a distraction. Computer programmers who can appreciate the programming detour, are mostly not that interested in logic. But this question hi
