Unbelievable facts
Scientists have studied a tiny metallic round object and believe it could be a microorganism deliberately sent by aliens to spread life on Earth.
Researchers at Buckingham University in the UK reported that a tiny metal ball was discovered by astrobiologist Milton Wainwright and a team of scientists who studied dust and small substances collected by a high-flying balloon in the Earth's stratosphere.

The size of the ball was no larger than the width of a person's hair with a fibrous structure on the outside. The structure consists of titanium and vanadium metals with a sticky biological fluid oozing from the center.
According to one theory, the object was created by intelligent beings to populate the planet with life.
Panspermia theory
The theory of panspermia, proposed by Nobel laureate Francis Crick, states that life is spreading through the known universe through comets and meteorites.
Francis Crick, a molecular biologist, has put forward the theory of directed panspermia, which states that organisms were intentionally sent to Earth by intelligent beings from another planet.
Scientist Wainwright launched a balloon 27 km into the Earth's stratosphere. When the researchers analyzed material collected by one of the balls, they found a tiny impact mark, which indicated that the microscopic round object did not land softly.
The sphere left an impact crater, the same as it remains on Earth when asteroids fall.
Alien life?
Although the origin or purpose of the mysterious sphere is unknown, experts believe it may contain genetic material.
Recently, scientists have found that DNA can be introduced into living things and reproduces in the harsh conditions of space.
For example, a tiny plasmid, a circular strand of DNA used in genetic engineering, was sent into space from Sweden in 2011 on the outside of the TEXUS-49 rocket.
Even after it endured a temperature of 1000 degrees C, it remained intact, retaining its biological properties after returning to Earth.
