A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder. By measuring the tiny vibrations of a trapped aluminum ion cooled to near absolute zero, the clock calculates seconds with a precision of 19 decimal places. As …

Our first meeting was a bit awkward. One of us is an archaeologist who studies how past peoples interacted with their environments. Two of us are geophysicists who investigate interactions between solar activity and Earth’s magnetic field. When we first got together, we wondered whether our unconventional project, linking space weather and human behavior, could actually bridge such a vast …

A massive planet trapped in a death spiral around its star could unlock some of the secrets surrounding star systems. However, the fate of this world is not yet set in stone, with two deaths and one “rebirth” possible in its future. The extrasolar planet or “exoplanet” in question is TOI-2109b, which has five times the mass of Jupiter and …

Giant 240-Million-Year-Old “Sand Creeper” Discovered in Retaining Wall  SciTechDaily Source link

A team of astronomers, led by researchers from the Shanghai Astronomical Observatory (SHAO), has uncovered an unexpected and intricate network of tangled, supersonic filaments within a very-high-velocity cloud (VHVC) named G165. This cloud, moving at 300 kilometers per second and located approximately 50,000 light-years from Earth, offers a unique glimpse into the early stages of interstellar cloud formation. Published in …

SpaceX added 24 new Starlink satellites to its orbital network on a Friday night (July 18) launch from California. The company’s Falcon 9 rocket lifted off at 8:52 p.m. local (11:52 p.m. EDT or 0352 GMT on July 19) from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base. At about nine minutes into the flight, the booster’s …

From Earth orbit to the Moon and Mars, explore the world of human spaceflight with NASA each week on the official podcast of the Johnson Space Center in Houston, Texas. Listen to in-depth conversations with the astronauts, scientists and engineers who make it possible. On episode 393, NASA’s SpaceX Crew-11 quartet each dive into their paths to space and what …

An exoplanet named WASP-127b just smashed the cosmic wind record. Astronomers clocked supersonic gales racing around its waist at about 20,500 miles (33,000 kilometers) per hour, which is seven times faster than fighter‑jet speed. “There is an extremely fast circumplanetary jet wind found on the planet. The velocity of the winds is surprisingly high,” said Lisa Nortmann of the University of …
