• An international team of scientists have collected the first possible radio signal from an exoplanet. 
• The exoplanet is 51 light years away from the earth.
• This is possibly the first radio signal received from a planet beyond solar system.
• The signals were received by a Low Frequency Array radio telescope located in Netherlands.
• The exo-planet is located in the Tau Bootes star-system. It hosts Jupiter like giant planet and the planet is close to its star.
• Also, the team of scientists have discovered an exoplanet in the star system that is emitting radio signals.

Tau Bootes

• The Tau Bootes is a binary star system with an exoplanet. The discovery of radio waves in the exo-planet of the star system will open up a new way examine the alien world. The radio waves help to learn about the magnetic field of the planet. This will in turn help the astronomers to decipher the interior of the planet and also study about its atmospheric properties.

Exoplanets

• They are planets outside the solar system.
• Doppler Spectroscopy and Transit Photometry are the best methods to detect Exoplanets.
• Exoplanets are hard to detect as they are close to the stars they are orbiting. Thus, the brightness of the stars prevents from being detected easily.
