Possible Radio Emission from Exoplanet Detected

From a Jupiter-like gas giant type exoplanet, which generate radio emissions through entirely natural processes just like the gas giants in our own solar system.<p>The title is a tad more spectacular than the actual discovery.

Radio JOVE is a STEM project that explores the radio emission of our own Jupiter, which is very similar to what has been detected in Tau Boötes. It&#x27;s a very fun backyard amateur radioastronomy project that&#x27;s great for kids.<p><a href="https:&#x2F;&#x2F;radiojove.gsfc.nasa.gov&#x2F;" rel="nofollow">https:&#x2F;&#x2F;radiojove.gsfc.nasa.gov&#x2F;</a>

There is a part of me who just thinks &quot;pah - click bait&quot;.<p>But then there is another, better, part of me that thinks it is so awesome we live in a time when people can build a machine that listens to &quot;sounds&quot; made deep in a giant planet in <i>another fricking solar system</i>.<p>To the team who built that machine and shared it with us - thank you. nice one.

Is “signal” the correct word to use for naturally occurring radio bursts? I thought that word implied radio waves used to convey meaning.

It seems that we expect an alien civilization, if it exists, to follow a similar discovery path as we did. As such we listen for radio signals as a way of communication, because that&#x27;s what we are doing.<p>How likely is it for another civilization to follow the same path? Some of our breakthrough scientific advances happened by accident. What are the odds that we missed some big new technologies because we haven&#x27;t happened upon the accident yet, even though it was right here all the time?

Posted earlier today (theguardian.com version):<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25464817" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=25464817</a><p>EDIT: Whoops, different radio emissions from a different place ! (but I&#x27;ll leave this here because it&#x27;s interesting anyway).

I am going to spoil this - it&#x27;s not aliens. The gap between Occam&#x27;s Razor explanations and THAT one is absolutely vast.

It&#x27;s not aliens. It&#x27;s never aliens.

&gt; The signal is from the Tau Boötes system, which contains a binary star and an exoplanet.<p>So, different to the signals from Proxima Centauri?<p><a href="https:&#x2F;&#x2F;www.theguardian.com&#x2F;science&#x2F;2020&#x2F;dec&#x2F;18&#x2F;scientists-looking-for-aliens-investigate-radio-beam-from-nearby-star" rel="nofollow">https:&#x2F;&#x2F;www.theguardian.com&#x2F;science&#x2F;2020&#x2F;dec&#x2F;18&#x2F;scientists-l...</a>

Also, in addition to this being an emission not a transmission:<p>&gt; “There remains some uncertainty that the detected radio signal is from the planet. The need for follow-up observations is critical,” he said.<p>So, in the terms used in everyday life, we do not (_c.f._ we do) have an indication that the signal is from the exoplanet.

A few years back, a researcher told me they were looking at when known exoplanet systems like Trappist have pairs that line up&#x2F;eclipse with Earth. They’d then look for interplanet comms&#x2F;laser signals.<p>Wonder how that’s turning out.

I&#x27;m still looking for intelligent life on <i>this</i> planet!

This is a first step for being able to distinguish natural from artificial radio emissions

It’s crazy that a radio emission could in theory and out of random luck be decoded into a coherent message, sent by no one. Very improbable though.

What would be a radio frequency that couldn&#x27;t possibly be natural?

First, they really missed an opportunity to rick roll everyone with this article. (just kidding)<p>But seriously, this went way over my head. If anyone can explain this to me like I&#x27;m 5, that would be awesome, I&#x27;m really interested in the subject but lack any real knowledge of the science.
