A Nasa probe into hundreds of UFO sightings found there was no evidence aliens were behind the unexplained phenomena, but the space agency also could not rule out that possibility.
If the truth is out there, this long-awaited report offers no conclusive evidence.
But it did outline how Nasa will investigate what it calls UAPs (Unidentified Anomalous Phenomena) with improved technology and artificial intelligence.
Nasa administrator Bill Nelson said the US space agency will not only take the lead in researching possible UAP incidents, but will share data with more transparency.
The report is 36 pages of quite technical and scientific observations, so here are some of the key takeaways.
There’s no proof aliens exist, but they might
The very last page of the report said “there is no reason to conclude” that extra-terrestrial sources are behind the hundreds of UAP sightings Nasa has investigated.
“However, if we acknowledge that as one possibility, then those objects must have travelled through our solar system to get here,” the report said.
Although the report did not conclude extra-terrestrial life exists, Nasa didn’t deny the possibility of “potential unknown alien technology operating in Earth’s atmosphere”.
