VIVA – The year 2020 will soon change to 2021. Many events have happened this year, apart from the COVID-19 pandemic. One of them is lunge alien. But unfortunately, scientists have not succeeded in finding and bringing aliens to Earth. Even so, astronomers claim to be closer to finding life outside the Solar System.
In fact, the former President of the United States (US) Barack Obama gives a signal that he believes in the existence of these living things that are claimed to be intelligent. Inevitably, the public was made excited by the former number one in Uncle Sam’s country.
“Of course I asked about it (the existence of aliens). But I can not tell you, sorry,” he said in an interview with Stephen Colbert, quoted from the website Express, Thursday, December 31, 2020.
Colbert thinks Obama’s answer is yes. If the answer is no, then he will definitely answer immediately that aliens do not exist. Although there is the potential for him to be joking, conspiracy theorists think Barack Obama really admits the existence of aliens.
“If Obama heard that UFOs were not real, then he could freely say. But because they were real and Obama knew them he could not say because they were. Matter of National Security, “said Scott C Waring, one conspiracy theorist.
Launch page Live Science, astronomers have been searching for everything from organic molecules that appear around the Solar System to mysterious radio signals. Here are some of the biggest findings regarding alien hiding places in the universe throughout 2020:
Life in the clouds of Venus
In September 2020, Venus became the most popular planet on Earth when scientists found traces of phosphine molecules in the planet’s atmosphere. On Earth, phosphine is associated with bacteria that do not breathe oxygen, as well as some human activities.
The molecule is naturally produced by the gas giant, but there is no good reason why it should be on Venus as hot as hell, according to the researchers. Unless there is life blowing it into the clouds on the planet Earth’s neighbor.
Even so, the discovery of phosphine was met with skepticism from the scientific community. The reason for this is that it’s not clear whether the researchers actually detected phosphine.
Their observations are still ambiguous because of the large amount of noise, so something mimicking the chemical signature of phosphine may appear accidentally, said John Carpenter, a scientist from Chile’s Atacama Observatory.
There are 36 alien civilizations
According to a study published in The Astrophysical Journal there are 36 intelligent civilizations in the Milky Way. This figure is obtained with decades of alien hunting puzzles, known as the Drake equation.
Astronomer Frank Drake started in 1961. He tried to guess the possible number of alien civilizations in our galaxy based on variables, such as the average star formation rate, the percentage of stars that make up the planets, and much smaller objects.
1,000 alien stars watching Earth
The journal Monthly Notices of the Royal Astronomical Society contains astronomers calculating the number of alien star systems, which have a direct line of sight to Earth.
The team calculated that there are about 1,000 star systems within 300 light years of Earth, which can easily see our planet.
The aliens will see and pass by Earth as the Sun begins to dim. Just like humans detect thousands of exoplanets by observing a star that suddenly fades in the night sky.
Aliens are not responsible for FRB
Fast radio bursts (FRB) are millisecond long radio light waves that travel through space thousands of times a day. Until recently no one knew what it was.
Could it be aliens or something that rattles a jet in high-speed space? Apparently, the source is a magnetar or a star carcass that has long been dead and rotating rapidly.
For thousands of years after their formation, these objects circled in circles and emitted intense X-ray vibrations and gamma-ray radiation into the universe around them.
The aliens may not breathe oxygen
Another target that is underestimated in the search for alien life is an oxygen-free planet. Although it has long been assumed that alien life needs air to breathe, a study published in Nature Astronomy argues that ‘air’ and ‘oxygen’ are not always the same. Hydrogen and helium are far more common elements in the universe.
The strange, cigar-shaped rock called Oumuamua has puzzled scientists since it was first seen in our solar system in October 2017. The object is moving too fast to have originated from the Solar System.
Harvard University astrophysicist Avi Loeb says that Oumuamua could be an alien spaceship powered by a paper-thin screen.
The world’s four most promising
In the Solar System there are four worlds that are likely to have life. The planet Mars is one of the most Earth-like worlds. The other three candidates are the moon, Europa – Jupiter’s Moon, as well as Saturn’s two moons, Enceladus and Titan.
The hunt for aliens got more difficult
On Tuesday, December 1, 2020, the Arecibo Observatory Radio Telescope in Puerto Rico collapsed. Previously, there were two incidents there, namely the mysterious disconnection of the cable during August and November, which then put the telescope into a terrible condition.
