Most connected devices use radio waves, be it WiFi or Bluetooth. Although it makes our lives more convenient, it’s making astronomers’ lives harder, according to Wired. Radio waves don’t just come from humans, they’re emitted by objects in space, and scientists can use them to analyze just about everything, from stars to nebulas to comets.
Right now, some radio wavelengths are reserved exclusively for radio astronomy. But that doesn’t mean they’re the only frequencies space sends towards Earth, and it’s getting harder to detect space’s signals through all the earthly noise. (Mysterious “alien” radio signals detected in Australia in 2015 were caused by a microwave, for example.)
Military and industry groups are working toward possible solutions, but they come with their own challenges. The best solution is to figure out how to share the spectrum, says Wired’s Sarah Scoles. “If you fill the spectrum with man-made
