A new AI-powered tool has reduced astronomers’ workload by 85% - filtering through thousands of data alerts to identify the few genuine signals caused by supernovae (powerful explosions from dying stars). The findings have been published today (10 Sept) in The Astrophysical Journal.
A pioneering study led by the University of Oxford in collaboration with international partners has applied AI for the first time to count the Great Wildebeest Migration from satellite images. Unexpectedly, the results showed fewer than 600,000 individual wildebeest – less than half the previous estimate of 1.3 million animals. The results have been published today (9 Sept) in PNAS Nexus.
A team of astronomers have observed an explosion in the universe unlike any ever witnessed before. The mysterious repeating gamma-ray bursts were spotted outside our own galaxy using the European Southern Observatory’s Very Large Telescope (VLT).
