Astronomers have measured the most powerful magnetic field ever found around a star.

Astronomers have measured the most powerful magnetic field ever found around a star.

The star’s magnetic field is 20,000 times stronger than the Sun’s, and almost 10 times stronger than that detected around any other high-mass star. At about 35 times the Sun’s mass, the O-type star NGC 1624-2 lies in the open star cluster NGC 1624, about 20,000 light-years away in the constellation Perseus.
