NASA Spots Slowest Magnetar

Astronomers have found evidence of a magnetar – magnetised neutron star – that spins much slower than the slowest of its kind known until now, which spin around once every 10 seconds.

The magnetar 1E 1613 – at the centre of RCW 103, the remains of a supernova explosion located about 9,000 light years from Earth – rotates once every 24,000 seconds (6.67 hours).

An instrument aboard NASA’s Swift telescope captured the release of a short burst of X-rays from 1E 1613.

The source is rotating once every 24,000 seconds (6.67 hours), much slower than the slowest magnetars known until now, which spin around once every 10 seconds.
