  • A team of scientists believes they may have detected radio emission from a distant exoplanet, which would be a first.
  • The planet is roughly 51 light-years away, and while there is still some debate over whether the signal is coming from the planet or the binary star it orbits, the data seems to indicate the planet is doing the "talking."
  • If confirmed, this could be a huge step toward further examining exoplanets in our neighborhood with greater detail than ever before.

Peering into space with optical or infrared telescopes can teach us a lot about what lies in the depths of the cosmos, but sometimes it's equally important to listen. In the case of the system named Tau Boötes, it seems that something is sending a radio signal into space, and in what might be a first for astronomy, scientists think they know what it is.

In a new paper published in the journal Astronomy & Astrophysics, researchers led by Cornell University suggest that the radio signal they are hearing is actually coming from a massive exoplanet hanging out near the binary star that hosts it. If this is confirmed, it will be the first time that scientists have been able to detect a radio signature from an exoplanet, and it could help unlock secrets about other planets outside of our solar system.
