Scientists Just Picked Up Radio Signals From an Alien Planet — And It's NOT Aliens

We finally got a radio signal from an alien planet.

Okay… before you start preparing your welcome-to-Earth speech, scientists say it's definitely NOT aliens.

But it's still a pretty wild discovery.

Astronomers have detected radio signals coming directly from a planet outside our solar system for the first time ever.

The planet is called Beta Pictoris b, and it's about 64 light-years away. It's also a monster — roughly 10 times the mass of Jupiter.

Researchers used the MeerKAT radio telescope array in South Africa to listen in on the distant system. They picked up rapid, repeating bursts of radio waves coming from the planet.

At first, scientists weren't sure if the signal was actually coming from the planet or from its star.

So they did some cosmic detective work.

By comparing the location of the radio signal with distant quasars — basically extremely bright objects that can be used as fixed reference points — researchers were able to pinpoint the source.

It was coming from the planet.

And that's a first.

So... What Is the Planet Saying?

Unfortunately, Beta Pictoris b wasn't trying to phone home.

Scientists believe the radio bursts are being produced by massive auroras.

Think of Earth's Northern Lights — except this planet's version could be dramatically more powerful.

The interaction between charged particles from the planet's star and the planet's magnetic field can create these powerful auroral emissions.

And that magnetic field is apparently ridiculously strong.

Researchers estimate Beta Pictoris b's magnetic field at around 1,250 gauss.

For comparison:

• Earth: about 0.5 gauss
• Jupiter: about 4.3 gauss
• Beta Pictoris b: about 1,250 gauss

Yeah. This planet is basically carrying a cosmic force field.

And This Could Help Us Find Habitable Worlds

The discovery isn't just cool because scientists picked up a mysterious signal from 64 light-years away.

Magnetic fields are important because they can help protect a planet's atmosphere from charged particles blasted out by its star.

That's especially important when scientists are looking at smaller planets that could potentially have conditions suitable for life.

Beta Pictoris b isn't considered a likely home for life. It's enormous and has a thick atmosphere.

But scientists now have another way to study the magnetic environments of planets that are far, far outside our solar system.

And This Is Just the Beginning

The MeerKAT telescope is essentially a preview of what's coming.

The much larger Square Kilometre Array is expected to come online in the coming years and will be significantly more powerful.

That means astronomers will be able to search many more planetary systems for radio emissions.

So, no, we haven't discovered aliens.

But for the first time, scientists have directly picked up a planet's radio "voice" from 64 light-years away.

And that's pretty damn cool.

Maybe keep the tin-foil hat handy, though.
