Using supercomputers, researchers have discovered how the rotation of these stars plays a crucial role in mixing materials between their cores and outer layers. For years, scientists have been trying to understand how the chemical changes in a star’s core affect its surface as it evolves into a red giant. This new discovery offers an
New research into how people perceive differences between colors is reshaping a theory first proposed nearly 100 years ago by physicist Erwin Schrödinger. Roxana Bujack, a scientist at Los Alamos National Laboratory, led a team that applied geometry to precisely describe how we experience hue, saturation and lightness. Their findings, presented at a major visualization
But in the worst worst-case scenario, we don’t have any control. Instead, the station will crack through the atmosphere. Sure, many pieces will likely end up in the ocean, but some might hit people, possibly in a town or a city. The station could break apart across thousands of miles and multiple continents. This would
CAPE CANAVERAL, Fla. (AP) — A telescope in Chile has revealed in unprecedented detail the swirling splendor of star-forming gases at the heart of our Milky Way galaxy. The picture released Wednesday by the European Southern Observatory zeros in on a region of cold cosmic gases more than 650 light-years across. A light-year is nearly
Horses, like the Norwegian fjord breed apparently yawning in this image, generate both a high frequency and a low frequency when they whinny. ullstein bild/Getty Images hide caption toggle caption ullstein bild/Getty Images Elodie Briefer grew up in the countryside near Geneva — and horses have long been a part of her world. “I was
NASA on Wednesday is set to roll its enormous Space Launch System rocket back to the hangar for repairs, a move that will delay the launch of four astronauts on a long-awaited flight around the moon by at least a month. The 322-foot-tall rocket has been sitting out at the launch pad at Florida’s Kennedy
A peculiar peanut-shaped object in the Kuiper Belt, Arrokoth, has intrigued astronomers since NASA’s New Horizons spacecraft visited it in 2019. The latest study offers a new understanding of how this bizarre snowman-shaped rock formed. Arrokoth is a contact binary, consisting of two distinct lobes that gently merged into one. Scientists have long wondered how
Six planets are linking up in the sky at the end of February, and most will be visible to the naked eye. It’s what’s known as a planetary parade, which happens when multiple planets appear to line up in the sky at once, the AP reports. The planets aren’t in a straight line, but
Space is full of odd light sources astronomers don’t quite understand, like double supernovas, weird blue flashes, random Venn diagrams, and more. And just when we thought we’d seen it all, there’s a new addition to the list—a natural “space laser” from the universe’s early days. Researchers using the MeerKAT radio telescope spotted an extremely
NEW YORK (AP) – Horses whinny to find new friends, greet old ones, and celebrate happy moments like feeding time. How exactly horses produce that distinctive sound – also called a neigh – has long eluded scientists. The whinny is an unusual combination of both high and low-pitched sounds, like a cross between a grunt
