PSR J1841−0500 is a
pulsar
A pulsar (from ''pulsating radio source'') is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Ea ...
located 22,800
light-years from the Sun in the
Scutum–Centaurus Arm of the
Milky Way. It was discovered in December 2008 by Fernando Camilo, who was using the
Parkes Observatory when he discovered the object. At the time of discovery, it was spinning once every 0.9 seconds.
However, in 2009, it stopped emitting pulses completely.
Most pulsars that stop emitting pulses only do so for a few minutes. But PSR J1841-0500 did so for 580 days. Then in August 2011, it started pulsing again.
In comparison, only one other pulsar is known to stop pulsing for more than a few minutes:
PSR B1931+24
