NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known orbits of more than 200 space objects completely ...

NASA's Roman Space Telescope is now enclosed inside its Falcon Heavy fairing and nearly ready for launch. Its mission could uncover thousands of exoplanets while helping scientists investigate dark matter, dark energy, and the accelerating expansion ...

A single asteroid impact may explain two of Deimos's most puzzling features: its huge southern depression and unusually smooth, dusty surface. Simulations suggest a roughly 320-meter asteroid struck the Martian moon at an angle, throwing debris ...

Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly how the catalyst works at the atomic level, the discovery could help .. ...

NASA scientists found that microbes brought by astronauts could survive in cold, shadowed niches around the Moon's South Pole, potentially complicating future searches for pristine lunar chemistry. Some refuges may be no larger than a footprint, ...

A massive test of gravity across the cosmos found that it behaves almost exactly as Newton and Einstein predicted, even across galaxy clusters hundreds of millions of light-years apart. The result weakens some modified-gravity explanations and ...

A faint ribbon of stars around a distant galaxy has become the first globular cluster stellar stream ever identified beyond the Milky Way. Because the stars trace the galaxy's gravity, researchers used the stream to estimate how much invisible dark . ...

Researchers have created a tiny chip that produces a stable "rainbow" of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks. Its extreme precision could also make it ...

More screen time during infancy and around the start of school was linked to poorer academic performance and weaker working memory years later. The findings suggest that early childhood may contain particularly sensitive windows when screen habits .. ...

Researchers have found a way to create a complete 3D image of a molecule's wavefunction, one of quantum mechanics' most fundamental yet elusive features. By combining advanced photoelectron measurements with newly designed algorithms, the University ...
