Astronomers used the James Webb Space Telescope to identify the galaxy that produced the farthest fast radio burst ever detected, first spotted in 2024 by the MeerKAT array. The source galaxy formed just 3 billion years after the Big Bang and is roughly 1,000 times smaller than galaxies linked to previously known bursts, which occurred billions of years later.
A study slated for publication in Physical Review D proposes that neutrinos switching between types inside a collapsing star's core could help resolve long-standing mismatches between supernova models and observations. Current simulations of core-collapse supernovae largely ignore this flavor-swapping behavior, even though neutrinos play a central role in triggering the explosion. The researchers suggest accounting for these identity changes could bring predicted supernova rates and outcomes closer to what astronomers actually observe.
