"They missed it because they hadn't expected to find anything like it."Astronomers have long been observing pulsars, which are highly magnetized neutron stars that rotate and shoot out beacons of energy, much like a lighthouse.
Now, a team of researchers has discovered a different kind of pulsar called a magnetar, which sends out even more powerful blasts of radio waves that repeats every 22 minutes — an astonishingly long period for such a celestial object., this particular magnetar dubbed GPM J1839−10 has been blasting out five-minute-long signals from 15,000 light-years away since 1988 — and at an incredible degree of accuracy, down to the tenth of a millisecond.
The astronomers are now left with an even bigger puzzle. What is J1839−10? Could it really be a magnetar in spite of its astonishing longevity?
