Researchers have discovered the cause of the brightest burst of light ever recorded.
But in doing so they have run up against two bigger mysteries, including one that casts doubt on where our heavy elements - such as gold - come from.
The researchers say the burst of light, spotted in 2022, is now known to have had an exploding star at its heart.
