PSR J1841−0500 is a pulsar located 22,800 light-years from the Sun in the Scutum–Centaurus Arm of the Milky Way.
At the time of discovery, it was spinning once every 0.9 seconds.
[2] However, in 2009, it stopped emitting pulses completely.
Most pulsars that stop emitting pulses only do so for a few minutes.
[2][3] In comparison, only one other pulsar is known to stop pulsing for more than a few minutes: PSR B1931+24 turns on for a week and then stops emitting pulses for a month in a cycle.
