Nasa regularly tracks radio signals coming from outer space – but was unable to determine its true origin [19659006MysteriousRadioBursts We sent dozens of our own signals into space – and hope for a callback.
However, we also receive many mysterious radio signals that we just can not explain.
These Fast Radio Bursts (or FRBs) are detected by tapping Tec hnology with computer systems that search through extensive data to find mysterious signals.
Back in September, the Breakthrough Listen program found 72 new FRBs from a galaxy three billion light-years away.
FRBs are single bright pulses of radio emission from extremely distant galaxies lasting only milliseconds.
But FRB 121102 is the only one ever repeated to emit repeated bursts.
The source of FRBs is still a mystery and the type of object it emits is still unknown. 19659002] Theories range from highly magnetized neutron stars and supermassive black holes to signs of advanced civilization.
The icy mystery of Saturn's moon
Earlier this year, scientists were able to sample organic molecules from outer space deep-sea vents on Enceladus, one of Saturn's moons.
It turned out that these material flags contained "all the basic requirements for life as we know it".
Enceladus is an icy moon orbiting Saturn, the sixth planet of the sun
. The problem is that life may have formed on a Saturn moons, the icy environment may just be too inhospitable.
And there's no way to tell if life on Enceladus really lurks unless we send a probe to the moon and start digging.
The Hidden Lake on Mars  In July 2018, scientists discovered a lake under a glacier on Mars.
It is the first known "stable" body of water on Mars, which is believed to measure approximately 12 miles (3.2 km).
Liquid water on other planets is a significant scientific opportunity for Na
The Mars Express probe used radar signals jumped through subterranean layers of ice to find evidence of a water pond buried under the South Pole cap
sa, as water is an integral part of life, such as we know it.
But the problem is that NASA (still) can not investigate the secrets of the lake because it lies almost a mile below the southern polar cap.
Scientists have discovered numerous exoplanets – planets outside our solar system – called "Earth." like ".
This means that they live in a" habitable zone "around their sun, where it is not too hot or too cold to keep liquid water on the surface.
To locate these exoplanets , is difficult Even more difficult is life.
Scientists have used space telescopes to find planets with "habitable zones" that carry liquid water such as water Kepler-186f could accumulate exoplanet
Scientists use space-based telescopes to spot faint traces of the existence of these planets.But they are often thousands of light-years away, meaning we simply can not examine them.
Although we know it's potentially life-sustaining planets, they remain a mystery for the time being.
The Fermi Paradox
The Fermi paradox is not a strict proof of alien le ben – but rather a thought experiment.
It is a famous contradiction that the physicist Enrico Fermi had made.
Fermi suspected that the size is enormous in the universe – and the billions of Sun-like stars in the galaxy and their planets – makes it very likely that there is an intelligent life there.
Some of these civilizations have developed interstellar travel.
But Fermi It has also been pointed out that there is a serious lack of evidence for life on other planets.
The chances that foreigners can reach us are high, but there is no evidence that foreigners ever have.
This paradox has baffled scientists for decades.
NASA allows it to be tiny Super Intelligent Aliens Have Visited the Earth Space Sugar
As early as 2012, astronomers at the University of Copenhagen discovered glycolaldehyde – a sugar molecule – in a distant star system, 400 light-years from Earth ,
Glycolaldehyde is important because it is necessary for the formation of RNA, a sister of DNA that is vital to life as we know it.
This star system is "Protostellar", ie the central star is still very young.

Which means that In early star systems, complex organic molecules can form even before planets themselves have formed.
Given the enormity of the universe, life seems possible.
But we simply have no hard evidence to prove it.
