As Harvard theoretical physicist Avi Loeb told New Scientist, however, the strangeness of the new signal, and it’s high frequency, may actually help make it easier to explain. “Previously, we thought there wasn’t much emission at high or low frequencies, but now it looks like there is,” he said. “It’s twice as high as the typical frequency that was previously claimed for this repeater.”

As we learn more, we’ll keep you posted.
