To find advanced #civilizations, you don’t need to go hunting for #megastructures or hypothetical #space probes.

You could find civilizations by looking for a key element: #hydrogen. #Deuterium holds a whole lot of promise for nuclear fusion.

To harvest deuterium, an alien civilization might draw it from its oceans. This would cause a visible imbalance in the deuterium-to-hydrogen ratio, potentially visible with next-generation telescopes.

Astronomy Magazine · Could deuterium be the key to finding aliens? Heavy hydrogen could be important in long-range detections of civilizations, says a pioneering astronomical study.

There are three ways to look for evidence of #alien technological #civilisations.

One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts.

Another is to look for evidence of them visiting the Solar System.

And a third option is to look for signs of large-scale engineering projects in #space.
