A strange radio signal pulsing from a spot 15,000 light-years away could point to an unconfirmed type of star.
Hurley-Walker and her team wanted to see if they could find other objects with similar behavior, so they took observations of the southern sky using thein Australia to conduct a survey. They found an object that emits five-minute bursts of radio light every 22 minutes.
They turned other telescopes to its coordinates, and scoured archival data of the location. The new observations allowed them to characterize the radio emission in detail, showing thesuggestive of alteration by a magnetic field. And the archival data showed that GPM J1839-10 has been caught pulsing since at least 1988.
"I was five years old when our telescopes first recorded pulses from this object, but no one noticed it, and it stayed hidden in the data for 33 years,"Infographic of all the observatories that observed GPM J1839-10.
