by In early 2020, we detected an unusual radio signal coming from somewhere near the center of our galaxy.
The signal blinked on and off, growing 100 times brighter and dimmer over time.
What's more, the radio waves in the signal had an uncommon "circular polarization," which means the electric field in the radio waves spirals around as the waves travel through space.
