Scientists solve "string of pearls" mystery in supernova 1987A with Crow instability explanation.

Scientists believe they have solved the mystery of the "string of pearls" formation in supernova 1987A. A new study suggests that the Crow instability, similar to the mechanism that breaks up airplane contrails, better explains the ring of hydrogen clumps surrounding the remnant of the star. This discovery provides insights into a longstanding astrophysical mystery, with the findings published in Physical Review Letters.
