For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million […]

NASA’s IXPE (Imaging X-ray Polarimetry Explorer) mission has taken a new observation of a supernova, RCW 86, seen here in an image released on March 24, 2026. This observation helps fill in a fuller picture of what other telescopes have seen. The full image combines IXPE’s data with legacy observations from two other X-ray telescopes: […]

A computer language designed to robustly verify mathematical theorems and expose logical flaws has been turned towards a physics paper – and spotted an error. The discovery raises questions about how many other papers may harbour similar issues
