Will alien technosignatures be detected before 1 January 2050?

Technosignatures are any measurable property or effect that provide scientific evidence of past or present technology, and are key to the search for extraterrestrial intelligence.

Technosignatures include (but are not limited to) evidence of electromagnetic transmissions of information, artificial heat and light, astroengineering projects (Dyson spheres and swarms, Matrioshka brains, stellar engines etc), asteroid or other space mining projects, and spacecraft.

This question asks: Will technosignatures of non-human origin be detected before 1 January 2050?

By 'non-human origin,' this question refers to technosignatures that are not the result of human activity, or of the activity of any technology or 'lifeform' created by humans, including any artificial intelligence system or biological organism.

To resolve positively, before 1 January 2050 a competent and credible authority on astronomy and or space exploration (such as NASA, ESA, ROSCOSMOS, CNSA, JAXA, SETI or similar) must announce that, on the balance of probabilities (i.e. more than 50% likely), technosignatures of non-human origin have been discovered. Evidence of biosignatures alone will not be directly relevant to the resolution of this question.


Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
