2021 has given truth seekers and alien hunters a lot of food for thought. From the long-awaited Pentagon report on military observations of UFOs to new discoveries about habitable exoplanets, and the truth about the so-called “alien signal” from the closest star to the Sun.
Here are 9 facts we learned about aliens (and where to find them) in 2021, according to Live Science.
UFOs are real and the government knows it
In June, the Pentagon released a highly anticipated report detailing 144 UFO encounters between 2004 and 2021. The report officially confirmed several UFO sightings, which until then had been disseminated only through the yellow media.
Anyone hoping for an extraterrestrial intelligence recognition, however, must have been disappointed when the report failed to link any of the 144 described events to alien activity.
Black holes could be alien power plants
The study, published in July in the Royal Astronomical Society’s Monthly Notices, warns that scientists should not lose sight of nature’s most extreme objects: black holes.
Because black holes can emit 100,000 times more energy than stars like our Sun, they can be tempting targets for alien civilizations looking to set their interstellar ventures in motion.
To do this, aliens could use high-tech structures called Dyson spheres to steal energy from a disk of white-hot matter swirling around the black hole’s horizon, and then send it into space. Researchers are currently developing algorithms to search for these re-emissions.
Alien planets may not look like Earth
Typically, the search for alien life begins with a search for planets similar to Earth. But there may be another class of alien worlds equally favorable to life, according to a study published in the Astrophysical Journal in August.
The giant planets, which are 2.5 times the size of Earth and are covered in huge oceans of liquid water under a hydrogen-rich atmosphere, could be ideal places for microbes.
Not only are these planets abundant in the Milky Way galaxy, they are also incredibly diverse. The authors write that all options have the potential to have life, which means that a whole new area of study could emerge for hunters for alien intelligence.
One of Saturn’s moons may still be inhabited
Methane emanating from Enceladus, the sixth largest moon of Saturn, could be a sign that life is abundant in its underground seas, a June study found. In 2005, NASA’s Cassini Saturn orbiter discovered geysers ejecting ice particles into space from cracks near the south pole of Enceladus.
This material is believed to come from a vast ocean of liquid water splashing beneath the icy shell. Scientists have found that methane microbes can contribute to the planet’s gas geysers, which means life on an icy moon cannot be ruled out.
Scientists can ignore “alien debris” in our solar system
According to a recent book by Harvard astrophysicist Avi Loeb, Aliens: The First Sign of Intelligent Life Beyond Earth, Oumuamua’s strange cigar-shaped object that flew through our solar system in 2017 is almost certainly part of alien technology.
In his book, Loeb argues that the object’s unusual elongated shape and apparent acceleration from the Sun suggest that Oumuamua is not natural in origin, but is part of alien technology – possibly thrown into our world by the solar system by accident.
Thousands of alien worlds could watch people grow
Although human efforts to find alien civilizations only began in the last century, more than 1,700 alien civilizations may have watched us thousands of years ago.
According to a study published in June in the journal Nature, 1,715 nearby star systems have had an ideal viewing angle of the Earth over the past 5,000 years. And over 1400 of them still have this image today.
“All of these stars are within 300 light years of our planet, and 75 of them are orbiting less than 100 light years away. Given that humans have been transmitting radio signals for about 100 years, any of these 75 star systems are close enough that “our radio waves have already covered them,” said lead author Lisa Kaltenegger, assistant professor of astronomy and director of the Carl Sagan Institute at Cornell University.
Another question is whether the civilizations living in these stellar systems want to communicate with us.
There is no perfect way to communicate with aliens
If aliens are watching us, what is the best way to tell them about yourself? Writer Joanna Thompson researched this issue in December, finding that no method is perfect.
On the one hand, radio waves are a tempting way to communicate with aliens because these signals are placed in a convenient gap in the electromagnetic spectrum called a “water hole.”
On the other hand, radio waves expand as they propagate, which means that any message we send will be the more blurry the farther from Earth it is.
Laser light does not have this problem, but laser signals require incredible precision and are unlikely to reach any alien observers unless we aim our message directly at their star system. Both methods have their advantages, and neither is perfect.
Our proprietary technology can get in the way
On April 29, 2019, astronomers discovered a signal going to Earth, most likely from Proxima Centauri, the closest star system to our Sun, where at least one potentially habitable planet is located.
Since the signal was caught in a narrow band of radio waves that planes or satellites rarely emit, the researchers interpreted this as a possible sign of alien technology.
But the signal was never repeated, and a study published this October in the journal Nature Astronomy explains why: The signal actually came from a faulty computer or cellular device near the telescope that detected it.
Alien Abductions Could Be Lucid Dreaming
Dreams, which humans are partially aware of and able to control, may explain so-called alien abduction stories, according to a study in July. The circumstances of the abduction often seem fabulous and cause feelings of horror and paralysis. Certain sleep states are known to induce similar feelings as well.
Scientists asked 152 lucid dreamers to dream of encounters with aliens or UFOs. And they found that a number of sleepers recounted dreams that resembled descriptions of alleged alien abductions.
Of those who described their dreams as “realistic,” 24% also experienced sleep paralysis and intense fear. Similar emotions often accompany reports of alleged alien abductions.
And while people describing their alien abduction may sincerely believe it was real, they likely experienced an extraterrestrial encounter during lucid sleep, the study authors said.
“Alien bases” may be hiding off the coast of Alaska, researchers say
An organization of civilian volunteers dedicated to the study of
unidentified flying objects (UFOs) has issued a statement based on
decades of studying eyewitness reports. According to Mutual UFO Network,
“alien bases” may be hiding off the coast of Alaska, reports the-sun.com.

analyzing reports from the ship’s crew from 1945, they hypothesized
that alien objects could be lurking underwater, off the coast of the
Alleged sightings of alien spacecraft nearly 80 years ago

Although these reports are nowhere to be found, UFO enthusiasts believe
the unidentified flying vehicles likely were used to commute to
different supposed alien bases hiding in the deep waters.
the “secret reports” of the sailors aren’t available, investigators

between points in the universe. UFO researcher Johnny Enoch added that
such objects could serve as a vehicle for aliens.
There are also
theories that other places on Earth could serve as bases for alien life.
A mountain in Seoul, South Korea is believed to be hiding a UFO,
according to Dr. Steven Greer.
An episode of the series “The
Alaska Triangle” features satellite imagery that claims to show one of
the “alien bases” in the Pacific Ocean off the coast of California.

Enormous City-Size Comet Racing Towards Earth Grows ‘Devil Horns’ After Massive Eruption
A volcanic comet the size of a mid-sized US city has
violently exploded for the second time in four months as it continues
racing toward the earth. And following the massive eruption, the cloud
of ice and gas sprouted what looked like a pair of gigantic devil horns.
The city-sized comet, named 12P/Pons-Brooks, is a cryovolcanic — or
cold volcano — comet. It has a solid nucleus, with an estimated diameter
of 18.6 miles, and is filled with a mix of ice, dust and gas known as
cryomagma. The nucleus is surrounded by a fuzzy cloud of gas called a
coma, which leaks out of the comet’s interior.
When solar radiation heats the comet’s insides, the pressure builds up
and the comet violently explodes, ejaculating its ice-cold innards into
space through seeping cracks in the nucleus’s shell.
Live Science report:
On Oct. 5, astronomers detected a large outburst from 12P, after the
comet became dozens of times brighter due to the extra light reflecting
from its expanded coma, according to the British Astronomical Association (BAA), which has been closely monitoring the comet
Over the next few days, the comet’s coma expanded further and developed its “peculiar horns,” Spaceweather.com
reported. Some experts joked that the irregular shape of the coma also
makes the comet look like a science fiction spaceship, such as the
Millennium Falcon from Star Wars.
The unusual shape of the comet’s coma is likely due to an irregularity in the shape of 12P’s nucleus, Richard Miles, a BAA astronomer, told Live Science after the comet’s previous eruption.
The outflowing gas is likely being partially obstructed by a notch
sticking out on the nucleus, Miles said. As the gas continues to expand
away from the comet, the irregularity in the coma’s shape becomes more
defined and noticeable, he added.
12P is currently hurtling toward the inner solar system, where it
will be slingshotted around the sun on its highly elliptical 71-year
orbit around our home star — similar to the green comet Nishimura, which
pulled off a near-identical maneuver on Sept. 17.
12P will reach its closest point to Earth on April 21, 2024, when it
may become visible to the naked eye before being catapulted back toward
the outer solar system. It will not return until 2095.
This is the second time 12P has sprouted its horns this year. On July
20, astronomers witnessed the comet blow its top for the first time in
69 years (mainly due to its outbursts being less frequent and harder to
spot during the rest of its orbit). On that occasion, 12P’s coma grew to
around 143,000 miles (230,000 km), which is around 7,000 times wider
than the comet’s nucleus.
It is unclear how large the coma grew during the most recent
eruption, but there are signs the outburst was “twice as intense” as the
previous one, the BAA noted. By now, the coma has likely shrunk back to
near its normal size.
As 12P continues to race toward the sun, there is a high probability
that we will witness several more major eruptions. It is possible that
those eruptions will be even bigger than the most recent one as the
comet soaks up more solar radiation, according to Spaceweather.com.
But 12P is not the only volcanic comet that astronomers are currently
monitoring: 29P/Schwassmann-Wachmann (29P) — the most volatile volcanic
comet in the solar system — has also had several noticeable eruptions
in the last year.
In December 2022, 29P experienced its largest eruption in around 12 years, which sprayed around 1 million tons of cryomagma into space. And in April this year, for the first time ever, scientists accurately predicted one of 29P’s eruptions before it actually happened, thanks to a slight increase in the comet’s brightness in the lead-up to the icy explosion.
