From space to deep under the ice: researchers face a cosmic mystery that seems to challenge the limits of physics.
NASA's Antarctic Impulsive Transient Antenna (ANITA) - a series of instruments suspended from balloons above Antarctica to detect radio waves produced by cosmic rays hitting Earth's atmosphere - first detected the strange radio signals between 2016 and 2018.
‘It looks more likely with each day we burn fossil fuels’: polar scientist on Antarctic tipping points
Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehend. Up until 2016, the sea icein Antarctica seemed relatively stable. Then everything started to change.At first, the decline was mostly in line with climate models. But suddenly, in 2023, there was an enormous drop. About 2.5 million sq km of Antarcticsea ice went missing relative to the ave…
