1. Black holes hide "super" civilizations

The Dyson sphere - a hypothetical energy-collecting object proposed by scientists more than half a century ago - may have been successfully invented and used by aliens.

A study published in July 2021 in Monthly Notices of the Royal Astronomical Society warns that astronomers are focusing too much on finding Earth-like planets and ignoring a potentially life-forming world. : black hole.

A black hole could provide 100,000 times more energy than a star like our Sun, a source of energy that nearby alien civilizations can collect using a high-tech structure called is a Dyson sphere. So the worlds around the black hole region need attention.

2. Don't look for planets like Earth!

Research published in August 2021 in the Astrophysical Journal confirms that the "Hyceans" - oceanic planets 2.5 times larger than Earth and with hydrogen-rich atmospheres are extremely suitable environments for microscopic life. extreme, life-like creatures that we've found underground, in underground lakes in ice, in craters. on Earth. Hycean planets are much more common than Earth-like planets.

3. Enceladus must have life!

Research published in June 2021, based on evidence of methane ejected from Saturn's moon Enceladus collected by NASA's Cassini spacecraft, confirms the moon's impressive "tiger stripes" are the area that sprays water ice particles into space, carrying a range of organic compounds. That is also where life is hiding in the underground ocean.

4. Oumuamua is an alien probe?

That is a claim that has been confirmed through layers of evidence, which have been gradually introduced over the years and especially in a book published in 2021 by astronomer Avi Loeb from Harvard University (USA). Oumuamua is a cigar-shaped asteroid, proven to be an extrasolar object. Dr. Loeb and his colleagues present evidence that its behavior is highly unusual and they believe it is a product of disguised technology from an extrasolar civilization.

5. Thousands of worlds have witnessed human evolution?

Earth seen from space

A study published in the journal Nature in June 2021 shows that from stars 300 light-years away, there are at least 1,700 habitable planets that can be observed on Earth. The work, led by associate professor Lisa Kaltenegger from the Carl Sagan Institute at Cornell University, confirms that many of these planets may have civilizations much more advanced than ours, capable of observing Earthlings evolve. while our technology is too weak to communicate with them.
