4 times people thought they had found out the Alien but finally they were wrong.

The answer for the mysteries that seems to come from outer space, turns out to be closer to us than imagined and embroidered for a long time.

1. Alien bones 

In 2003, a collector found a leather bag containing a 15cm long skeleton, thought to be the alien's bones who had landed on Earth in the past because the mummy had large sockets and a long skull.  As a result, over the next 15 years, the rumors were woven around this mysterious mummy, and the mummy was also frequently given evidence to prove the existence of extraterrestrial life. 

But recently, thanks to gene therapy, the true truth about this skeleton is clear: this is not an alien mummy, but a child's genetic mutation linked to bone. This type of mutation is extremely rare, with no previously documented record of it.  And as a result we are once again mistaken for the presence of aliens, like many other times in history.

Back in the skeleton, scientists have been putting a lot of energy in place in 2013 to find a way to explain why Ata (the name of a skeleton) is about the size of a fetus. Bones develop as children between the ages of 6 and 8.  Until now, five years later, thanks to Ata's analysis of DNA, scientists have the answer: it's a mutation in seven chromosomes related to bone of people.

2. Signal from distant universe 

In the summer in 2017, astronomers at the Arecibo Observatory received a strange radio signal from an asteroid called the Ross 128. However, the true origin of the signal is still within the mystery, because If it came from a solar storm on Ross 128, there would be no frequency what astronomers received.  Then another theory, is that this signal is sent from aliens living at Ross 128, and like us, are they looking for signs of alien life?

The answer is no. Unfortunately, just a week later, astronomers have come up with the answer: this signal comes from a satellite we just launched, and it sends a signal when it passes by. space between Earth and Ross 128.

Bringing aliens into the conversation before eliminating every other possibility might seem surprising, but not if you consider the source of this new information. The Breakthrough Listen Initiative is a $100 million project with the express directive of looking for signals from extraterrestrial civilizations. So upon finding something strange and not immediately explainable, of course they’re going to bring up aliens. It’s their job to hold that up as a possibility until the evidence shows otherwise.

But there are plenty of other avenues of research that provide possible explanations for the repeating burst. Many of these are thrilling and exciting, and most of them are definitely not aliens.

3. Glittering Stars

The star is also known by the name of Tabby, whose scientific name is KIC 8462852, and it attracts the attention of astronomers because the star regularly abnormally blinks and does not follow. any rule at all.  Many people say that the reason this star is blinking is because it is not a star, but a giant structure built by outsiders. Immediately, the star fell into NASA's "need to track", when they used the Kepler telescope to track KIC 8462852 for 1600 days.

The study revealed that the Milky Way’s bulge is a dynamic environment of variously aged stars zipping around at different speeds, like travelers bustling about a busy airport.

The researchers also found that the motions of bulge stars are different, depending on a star’s chemical composition. Stars richer in elements heavier than hydrogen and helium have less disordered motions, but are orbiting around the galactic center faster than older stars that are deficient in heavier elements.

However, by January 2018, a group of astronomers announced the cause of the bizarre blur: the cosmic dust that caused the brightness of the star to change. often.  Of course, where the dust from the universe came from is still in the mystery. Only human beings have once again "missed an appointment" with outsiders.  

4. The gap between the pyramid 

In December 2017, scientists announce the discovery of a hollow cavity in the Pyramids of Giza. Through the use of X-rays, they tracked the movement of muon particles through the pyramid, thereby detecting the existence of this cavity, with a length of more than 30 meters.  Scientists have called this hollow cavity Big Void, and they have yet to get an accurate answer about its formation.And Egyptologists believe it could finally shed light on how the ancient tombs were constructed.

The enigmatic gap, which is around 100ft long is situated directly above the Grand Gallery, an elaborate access route which cuts through the pyramid.

It was found using a state-of-the-art scanning process called ‘muography’ which picks up tiny cosmic particles known as muons.However, the team claims that the hollow is made up of the intentions of the pyramid builders, not aliens. Unless, this pyramid is actually an alien product, then it is another story.
