The ASKAP radio telescope in Australia detected the ASKAP J1935+2148 signal, which has a pulsation period of 53.8 minutes.
The signal is cycling through three states: bright flashes that last between 10 and 50 seconds and have a linear polarization (all waves pointing in the same direction), weaker pulses with a circular polarization that last 370 milliseconds, and sometimes the object is inactive at the 53.8-minute mark.
"What is intriguing is how this object displays three distinct emission states, each with properties entirely dissimilar from the others," said Dr. Manisha Caleb, lead author of the study, in a statement. "The MeerKAT radio telescope in South Africa played a crucial role in distinguishing between these states. If the signals didn't arise from the same point in the sky, we would not have believed it to be the same object producing these different signals."
These active emission states have evolved over a period of eight months, suggesting there may be physical changes in the area that's producing the emission.
