NASA Study: A Lot Of Extraterrestrial Artifacts Could Be Hidden On Our Planet

You could believe that the greatest approach for mankind to discover extraterrestrial life is to go far into space and analyze distant galaxies.

However, according to NASA research, the truth concerning extraterrestrials might be right beneath our noses.

Hundreds of space experts have joined forces to investigate how our species can discover ‘technosignatures,’ or evidence that indicates the presence of advanced extraterrestrial civilizations.


The truth may be discovered not in space, but on our own planet.

Some of these warning indicators are unmistakable. For example, if a large number of radio waves are discovered emanating from a distant star system, this might be a sign that it is home to intelligent extraterrestrial life.

We may potentially explore extraterrestrial civilizations by looking for Dyson Spheres, which are hypothetical power plants placed around a star to harness its energy.

Because they are expected to be enormous and block out starlight whenever they pass in front of their sun, they would be simple to see.

Other technosignatures, such as indications that a planet has been contaminated by major industries, are more difficult to spot.

In the latest paper, scientists also make the intriguing claim that our planet might be harboring extraterrestrial ‘artifacts,’ some of which could have been produced by extinct civilizations from Mars, Venus, or perhaps Earth.

‘Because the geological, paleontological, and archaeological records on Earth are so incomplete, it is even possible that the Earth itself hosts such artifacts,’ researchers wrote. ‘However, this idea is often conflated with unscientific popular imaginings and science fiction stories about alien visitation, and so must be approached with caution.’

‘If interstellar technosignatures were detected in the solar system, it would be worth examining their origin.’

‘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 early stages of development), the Earth 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.’

Our species has only discovered one possible extraterrestrial item so far, however, most experts believe it was created naturally rather than artificially.


‘Oumuamua,’ which means messenger in Hawaiian, is depicted by an artist.

‘Oumuamua,’ a comet, asteroid, or extraterrestrial vessel, blasted past our solar system at breakneck speed in 2017. After journeying through deep space, it was the first ‘interstellar visitor’ to be seen in our stellar neighborhood.

It altered course when it crossed the sun, which might have been produced by a natural process called outgassing – however, there’s a chance it was guided in some way.

Some scientists speculated that ‘Ouamuamua was an alien probe, while others speculated that our solar system may be teeming with such extraterrestrial ships.

Unfortunately, the agreement is that it was a comet that was expelled from a distant star system and dispatched on a long trip across space.

Scientists added the following to their most recent study:

‘Technosignatures in the solar system might include free-floating probes or structures moving through the solar system or in orbit around the Sun or another body, or structures or other evidence of technology on planetary surfaces.’
