Harvard-based Galileo Project will search for evidence of extraterrestrial life from the alien technology.
Extraterrestrial life is hypothetical life that may exist or may have existed in the universe outside of Earth maybe in exoplanets.
An exoplanet is any planet outside our solar system that can orbit other stars, or can be a free-floating exoplanet also called a rogue planet.
The first exoplanets were discovered in the 1990s and since then thousands of exoplanets were discovered using a variety of detection methods.
It is very rare for astronomers to see an exoplanet through their telescopes which are called direct imaging. A very few exoplanets were discovered through direct imaging.
Most of the exoplanets are found through indirect methods like measuring the dimming of a star that may occur due to a planet passing in front of it, called the transit method, or another method is through Doppler shift.
