Through the use of technosignatures, such as atmospheric pollution, radio signals, and spacecraft activity, scientists could make connections to an alien civilization far from Earth. Compared to biological clues, technological clues can be considered more common and easier to detect. Researchers at Pennsylvania State University have found that the search for intelligent life in other worlds could be closer than previously assumed. Similar to artificial products used on Earth, technosignatures could be used far into the future, since technology has the capability of outliving its creators. However, while searching for technosignatures should be taken seriously, this does not mean that biosignatures should be tossed aside.
Key Takeaways:
- Radio signals, spacecraft activity and pollution in the atmosphere are all examples of technosignatures.
- There is new research that shows it is possible that the number of planets that have technosignatures may be greater than those that have signs of biological life.
- The paper goes into the idea that it may be easier to sport aliens from Earth than any other inhabited world.
“Wright and his colleagues argue that the raw mathematics of the search for intelligent life on other worlds might be less daunting than we’ve long assumed.”
