Astronomers believe they’ve uncovered the source behind mysterious cosmic signals known as fast X-ray transients (FXTs) — and it adds a grim twist to our understanding of the death of stars. Right as a massive star explodes in a supernova, it unleashes a tremendously energetic stream of particles called a jet, producing a gamma ray burst — one of the most …

Durham University scientists examining radar images of the ice sheet above the east coast of Antarctica have discovered an 80-million-year-old ancient landscape hidden beneath the ice that is filled with mysterious flat surfaces. The scientists suggested this hidden array of flat surfaces was preserved by the ice sheet rather than eroded over the millions of years since. The research team …

NASA’s Juno spacecraft has unveiled an exciting breakthrough: the discovery of an entirely new type of plasma wave near Jupiter. These waves, unlike any previously observed in space, provide fresh insights into the mysterious behavior of the gas giant’s auroral plasmas. Scientists believe these waves play a critical role in the unique auroras visible at Jupiter’s poles, expanding our understanding …

Antarctica’s waters are getting saltier and driving a collapse in its sea ice — and scientists aren’t sure why. Antarctic sea ice has been declining since 2015, defying model predictions to hit a record 0.6 million square miles (1.55 million square kilometres) below its expected average extent in 2023. At winter’s peak in July of that year, the region was …

Giant sand mounds beneath the North Sea have puzzled scientists for years. Now, researchers have discovered that these mysterious structures were created by a geological process that has never been seen on such a huge scale. Seismic data and rock samples from the northern North Sea, off the coast of Norway, suggest that these miles-wide mounds sank millions of years …

A radar station on Hainan Island in China has recently made an extraordinary discovery—plasma bubbles in Earth’s ionosphere, located over the Pyramids of Giza, Egypt. This remarkable event marks a breakthrough in global space weather monitoring and reveals the increasing potential for long-range ionospheric tracking. In an age where satellite communications and navigation systems are vital to everyday life, such …
