Scientists expected a black hole but found a neutrino factory powered by stars
Astronomers using the ALMA telescope discovered that a distant galaxy, previously thought to be powered by a black hole, is actually a 'neutrino factory' driven by intense star formation. This finding helps explain the origin of high-energy neutrinos that have puzzled scientists.
Why it matters
This discovery provides a new explanation for the source of mysterious high-energy particles in the universe, shifting the focus from black holes to star-forming regions.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have tracked down the source of a powerful neutrino burst with the help of a remarkable cosmic phenomenon that acted like a natural telescope. What they discovered challenged expectations.
