The project will use new and existing telescopes to search for mysterious artifacts hidden in Earth orbit.

Do aliens really exist? That is a question that perhaps in a short time we will be able to answer, as astrophysicist Avi Loeb of Harvard University announced a plan to search for life outside planet Earth: the Galileo project.

In the year 2022, an oddly shaped object zoomed past the Sun and Earth. While many scientists think the cigar-shaped visitor, less than 1 kilometer long, was a comet or asteroid from a nearby star or some other cosmic wreck, this was not the case for Avi Loeb.

The object, called "Oumuamua," which means "explorer" in Hawaiian, was an extraterrestrial creation : a light sail, an antenna, or even a spacecraft, the Harvard astrophysicist maintains.

According to the scientific journal Sciense, the researcher will use new and existing telescopes to systematically search for mysterious artifacts that could be hidden satellites in Earth orbit, interstellar objects, whether natural or manufactured, and even unexplained spacecraft in the Earth's atmosphere

With an investment of 1.75 million dollars, obtained from wealthy people interested in the subject, the Galileo project proposes to use data from existing and future survey telescopes to search for more objects like Oumuamua.

The goal will be to obtain high-quality images of unidentified aerial phenomena, such as those recorded by US national intelligence.

A one-meter telescope with a modern sensor can see details as small as a millimeter in an object a kilometer away, Loeb says, and such an instrument can be ordered off the shelf for $500,000.

Funding permitting, it would place dozens of these telescopes in strategic positions around the world to scan, with the help of radar and infrared sensors, the skies for unidentified aerial phenomena.

A third part of the project would involve searching for extraterrestrial satellites in orbit around the Earth using artificial intelligence techniques to process data from existing reconnaissance telescopes.

Within the scientific community, opinions regarding the Galileo project are divided. Several researchers think that it is a waste of time since there is already very capable surveillance in space, such as that of United States intelligence. Others can't wait to see the discoveries.
