It's quiet out there: scientists fail to hear signals of alien life
Astronomers have come up empty-handed after scanning the heavens for signs of intelligent life in the most extensive search ever performed.
Researchers used ground-based telescopes to eavesdrop on 1,327 stars within 160 light years of Earth. During three years of observations they found no evidence of signals that could plausibly come from an alien civilisation.
[...] During the three-year effort, the astronomers scanned billions of radio channels and filtered out any signals that appeared to come from nature or equipment on Earth. Having dismissed millions of signals this way, the team was left with only a handful of "events". On closer inspection, these too turned out to have prosaic explanations.
The Breakthrough Listen team described their latest attempt to track down ET in two papers released on Tuesday, which made all the data available to the public. "There could be a signal in the data that we didn't detect this time around, but others can now look through it to see if we missed anything," Price said.

If they do, and we start mining ours for heavier elements and extend its lifespan several times over, would it thank us?
