The year 2021 has provided enough fodder for truth searchers and alien hunters alike. From the long-awaited Pentagon study on military UFO sightings to new findings regarding habitable exoplanets to the truth about the so-called “alien signal” from the nearest star to the Sun, there’s a lot to learn.
In 2021, we learned nine new things about aliens (and where to locate them).
UFOs exist, and the government is aware of this.
The Pentagon issued a long-awaited study in June covering 144 UFO sightings between 2004 and 2021. The investigation corroborated multiple UFO sightings that had previously only been reported through the yellow press.
Those seeking for a confirmation of extraterrestrial intelligence must have been disappointed when the study failed to relate any of the 144 instances detailed to alien activities.
It’s possible that black holes are extraterrestrial power plants.
The research, which was published in the Royal Astronomical Society’s Monthly Notices in July, urges scientists not to overlook nature’s most extreme objects: black holes.
Because black holes may radiate 100,000 times the energy of stars like our Sun, they can be enticing targets for extraterrestrial civilizations planning interstellar missions.
Aliens may achieve this by stealing energy from a disk of white-hot matter whirling around the black hole’s horizon and sending it into space using high-tech devices known as Dyson spheres. The hunt for these re-emissions is now being developed by researchers.
Alien worlds may not resemble Earth in appearance.
The quest for extraterrestrial life usually begins with a look for planets that are comparable to our own. According to a research published in the Astrophysical Journal in August, there may be another type of extraterrestrial worlds that are as hospitable to life.
The gigantic planets, which are 2.5 times the size of Earth and have vast seas of liquid water beneath a hydrogen-rich atmosphere, might be excellent environments for bacteria.
Not only are there a lot of these planets in the Milky Way galaxy, but they’re also very different. According to the authors, all choices have the potential to have life, implying that a whole new field of research for extraterrestrial intelligence searchers might arise.
It’s possible that one of Saturn’s moons is still populated.
According to a June research, methane emitted by Enceladus, Saturn’s sixth-biggest moon, might be a hint that life is plentiful in its subsurface waters. Geysers ejecting ice particles into space from fractures near Enceladus’ south pole were identified in 2005 by NASA’s Cassini Saturn spacecraft.
The source of this substance is thought to be a massive ocean of liquid water gushing underneath the frozen shell. Methane microorganisms have been discovered to contribute to the planet’s gas geysers, implying that life on an ice moon cannot be ruled out.
“Alien junk” in our solar system can be ignored by scientists.
Oumuamua’s unusual cigar-shaped object that traveled through our solar system in 2017 is very probably part of extraterrestrial technology, according to Harvard scientist Avi Loeb’s latest book, Aliens: The First Sign of Intelligent Life Beyond Earth.
In his book, Loeb claims that Oumuamua’s odd elongated shape and apparent acceleration from the Sun indicate that it is not of natural origin, but rather a product of extraterrestrial technology that was accidentally hurled into our planet by the solar system.
Thousands of extraterrestrial worlds might be watching humans develop.
Despite the fact that human efforts to identify extraterrestrial civilizations had just begun in the last century, over 1,700 alien civilizations may have been watching us for thousands of years.
According to a research published in the journal Nature in June, over the past 5,000 years, 1,715 neighboring star systems have had a perfect viewing angle of the Earth. And this image may still be seen on over 1400 of them now.
“All of these stars are within 300 light-years of our planet, with 75 circling within 100 light-years.” Given that humans have been sending radio signals for about a century, any of these 75 star systems are close enough that “our radio waves have already covered them,” according to lead author Lisa Kaltenegger, an assistant professor of astronomy and director of Cornell University’s Carl Sagan Institute.
Another concern is if the civilizations inhabiting these star systems are interested in communicating with us.
There is no perfect method for communicating with extraterrestrials.
What is the greatest method to tell aliens about yourself if they are monitoring us? Joanna Thompson, a writer, investigated this topic in December and discovered that no solution is flawless.
On the one hand, radio waves are a tempting approach to communicate with aliens since they are sent via a “water hole” in the electromagnetic spectrum.
Radio waves, on the other hand, expand as they travel, so any message we broadcast will become increasingly hazy the further we go from Earth.
This is not an issue with laser light, but laser communications need extreme accuracy and are unlikely to reach any extraterrestrial viewers unless we point our message exactly at their star system. Both systems have their merits, yet none is without flaws.
It’s possible that our proprietary technology will get in the way.
Astronomers found a signal traveling to Earth on April 29, 2019, most likely from Proxima Centauri, the nearest star system to our Sun, which has at least one possibly habitable planet.
The researchers interpreted the signal as possible evidence of alien technology since it was intercepted in a limited range of radio waves that planes or satellites seldom release.
The signal, however, was never replicated, as explained in a research published in the journal Nature Astronomy in October: The signal was picked up by a malfunctioning computer or cellular device near the telescope.
Alien abductions may be the result of lucid dreaming.
According to research published in July, dreams, which people are partially aware of and control, may explain so-called extraterrestrial abduction accounts. The circumstances of the kidnapping are frequently fantastic, causing terror and paralysis. Similar sensations have been reported to be induced by certain sleep stages.
Scientists recruited 152 lucid dreamers to have dreams about contacts with aliens or unidentified flying objects (UFOs). They also discovered that a lot of sleepers had nightmares that sounded similar to reports of suspected extraterrestrial abductions.
Sleep paralysis and acute terror were reported by 24 percent of individuals who characterized their nightmares as “realistic.” Reports of reported extraterrestrial abductions are frequently accompanied by similar feelings.
While persons who claim to have been abducted by aliens may honestly think it happened, the research authors believe they had an extraterrestrial contact while sleeping.
