According to a NASA study, there might be a lot of alien artifacts on our planet.
You might think that the best way for humanity to find extraterrestrial life is to go far into space and study distant galaxies.
According to NASA study, however, the truth about extraterrestrials may be right under our noses.
Hundreds of space specialists have banded together to figure out how our species can find ‘technosignatures,’ or signs that advanced alien civilizations exist.
The truth may be discovered on our own planet, rather than in space.Some of these warning signs are easy to spot. If a huge quantity of radio waves are detected emerging from a distant star system, for example, this might indicate that it is home to intelligent extraterrestrial life.
We may seek for Dyson Spheres, which are hypothetical power plants erected around a star to collect its energy, to investigate extraterrestrial civilizations.
They would be easy to spot since they are predicted to be massive and block out starlight whenever they pass in front of their sun.
Other technosignatures, such as evidence of a planet’s contamination by big businesses, are more difficult to detect.In their recent research, scientists also speculate that our planet may be home to extraterrestrial ‘artifacts,’ some of which might have been created by extinct civilizations from Mars, Venus, or perhaps Earth.
‘Because Earth’s geological, paleontological, and archaeological records are so sparse, it’s even plausible that such items are found on the planet itself,’ researchers said. ‘However, because this theory is sometimes confounded with unscientific popular imaginings and science fiction stories about extraterrestrial visitation, it should be addressed with care.’
‘It would be worthwhile to investigate the origin of interstellar technosignatures if they were identified in the solar system.’
‘Specifically, because the Earth is home to the only known species capable of interstellar communication and planetary travel (despite the fact that both technologies are still in their infancy), it remains the only known planet fecund enough to support technological life, and thus it, or an early, habitable Mars or Venus, could even be the origin of such technology.’
So yet, our society has only uncovered one probable alien object, although most scientists believe it was made naturally rather than purposely.
In 2017, a comet, asteroid, or alien spaceship known as ‘Oumuamua’ sped through our solar system at breakneck speed. It was the first ‘interstellar visitor’ to be sighted in our stellar neighborhood after traveling through outer space.When it crossed the sun, it changed direction, which may have been caused by a natural process called outgassing, but there’s also a chance it was steered in some manner.
