Astronomers around the world were universally fascinated in 2017 when 1I/2017 U1 came cruising through the solar system. This object, known more than commonly every bit ʻOumuamua, was the very starting time interstellar visitor to be detected in our solar system. Harvard astrophysicist Avi Loeb has gained a measure of notoriety for his merits that ʻOumuamua could be a piece of conflicting engineering. At present, a group has backed an initiative called The Galileo Projection, which will allow Loeb and others to search for more interstellar objects with the hope that i of them will be indisputably conflicting in origin.

ʻOumuamua started all this, but sadly, we will probably never know what it really was. The probable space rock appeared in the Pan-STARRS telescope when it was already heading out of the solar system. However, its speed and orbital trajectory proved it was not native to this role of space. It was moving and then fast that no current spacecraft would be able to catch up, and it was far enough away that we couldn't get a skillful await at it. Its properties were very unusual, though. That's what led Loeb to go out on a limb and call information technology conflicting technology.

For one, ʻOumuamua isn't shaped like the other chunks of rock we see floating around the solar system. It's either a rod or pancake shape, either of which would exist pretty odd. It also appeared to be tumbling with uneven rotational periods. Perhaps almost perplexing is the small just detectable dispatch as it spun off into space. This has been attributed to comet-like outgassing that was too faint to appear in scopes, merely Loeb and his supporters say this supports the idea ʻOumuamua is alien technology. For example, a piece of a defunct solar sail.

The Galileo Project is funded with most $1.75 million from a group of wealthy backers. Loeb and others will use World-based telescopes to continue the hunt for more interstellar objects — it would be foolish to think ʻOumuamua was literally the outset… something to migrate through our solar arrangement on its mode to someplace else. It was simply the offset one we saw. That implies in that location are more of them out there, and detecting them volition aid us empathize more about the universe outside our footling pocket of it. If nosotros're lucky, maybe one of them will even be an alien.

Loeb describes The Galileo Projection as complementary to SETI, which uses radio telescopes to search for alien life. The project will also explore unidentified aerial phenomena (UAPs). A United states of america intelligence written report terminal month listed more than 100 UAP sightings since 2004. The Galileo Projection speculates that UAPs could exist elements of alien applied science as well. Of course, in that location is no proof of this. The point of The Galileo Project is to go looking for some.
