Ok this sounds like a reasonable strategy so how would one know what to look for in terms of signaling of this type of environment? Basically they use this strategy:
Many exoplanet scientists turn to models to understand how Earth might appear if it were a distant alien world. However, the accuracy of these models can be difficult to gauge without observations to verify them.
That sounds like a good idea. And why not look for exoplanets with this feature and maybe keep it in a certain distance for further evaluation as opposed to star systems that are billions of light years away.
And here is a video about one of the most interesting exoplanets that you may have heard about:
Exoplanet Kepler 452b with SETI Institute scientists Douglas Caldwell, Jeffrey Coughlin, Joseph Twicken. Hosted by Seth Shostak.
We hope you enjoy the video!
