First Confirmed Radio Signal Localized to an Exoplanet — Beta Pictoris b

For the first time, we've caught a radio signal coming from a planet outside our solar system — and this time we know it's the planet, not the star.

There have been hints before, but astronomers could never rule out that the emission was actually coming from the host star. What's new here: the team localized the signal to Beta Pictoris b itself, a gas giant orbiting a star just 23 million years old — a baby compared to our 4.5-billion-year-old system. The planet was discovered back in 2008; this is a brand-new way of seeing it.

Radio observations could give us "a completely new view on planets beyond our system." — astronomer Joseph Callingham, Anton Pannekoek Institute for Astronomy, University of Amsterdam

We're not saying it's aliens. We're saying it's a brand-new sense we didn't have before — and the universe just got a little more audible. Radio emission from a planet can reveal things light can't: magnetic fields, the churn of an atmosphere, the physics of a world we will never visit.

If you could point the most sensitive radio telescope anywhere in the sky, where would you aim it first?
