By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes – that could be the first radio emission collected from a planet beyond our solar system. 1/nhttps://news.cornell.edu/stories/2020/12/cornell-postdoc-detects-possible-exoplanet-radio-emission …
“We present one of the first hints of detecting an exoplanet in the radio realm. The signal is from the Tau Boötes system, which contains a binary star and an exoplanet. We make the case for an emission by the planet itself." Dr. Jake Turner (@Astro_journey, Cornell postdoc)

"From the strength and polarization of the radio signal and the planet’s magnetic field, it is compatible with theoretical predictions.” Dr. Jake Turner (@Astro_journey, @Cornell postdoc, @CSInst fellow)

“If confirmed through follow-up observations, this radio detection opens up a new window on exoplanets, giving us a novel way to examine alien worlds that are tens of light-yrs away.” Dr. Ray Jayawardhana (@DrRayJay, Cornell Dean of the College of Arts & Sciences)

Using the Low Frequency Array (@LOFAR), a radio telescope in the Netherlands, Turner (@Astro_journey) & his colleagues uncovered emission bursts from a star-system hosting a hot Jupiter, a gaseous giant planet that is very close to its own sun.

Observing an exoplanet’s magnetic field helps astronomers decipher a planet’s interior and atmospheric properties, as well as the physics of star-planet interactions, said Dr. Jake Turner (@Astro_journey)

“The magnetic field of Earth-like exoplanets may contribute to their possible habitability,” Turner (@Astro_journey) said, “by shielding their own atmospheres from solar wind and cosmic rays, and protecting the planet from atmospheric loss.”

The signature, though, is weak. “There remains some uncertainty that the detected radio signal is from the planet. The need for follow-up observations is critical."

Turner & his team have already begun a campaign using multiple radio telescopes to follow up on the signal from Tau Boötes.
So stay tuned!
