Those weird radio waves that were puzzling astronomers have a new explanation

Those weird radio waves that were puzzling astronomers have a new explanation:

Last week, astronomers at the Arecibo Observatory in Puerto Rico announced they had picked up some strange radio signals coming from a small red dwarf star, and they couldn’t quite figure out what was causing them. Now, it seems they have an answer: it turns out these bizarre radio signals most likely came from the transmissions of a couple of satellites.

The radio signals initially perplexed the astronomers. A solar flare from the star could have caused the signals, but the waves weren’t at the right frequency. The astronomers said it was possible that the waves came from nearby satellites, but the structure of the signal made it seem like the waves had traveled a long way through space to reach Earth. No explanation perfectly fit the...
