Search for life outside the world | Life Beyond Earth | Extraterrestrial Life | Is there Life Beyond Earth Part-3

Search for life outside the world

We used to love the idea of ​​extraterrestrials in other parts of the universe. The idea that laid the foundation for much of the scientific economy story was limited to our imagination. But could other living things exist in the vast expanse of space or on other planets or moons? And there is another kind of life outside the world - are we likely to find something easy?

Where are the strangers?

The sun is the only star, and our galaxy is not a billion. In recent years, scientists have discovered thousands of planets orbiting other stars, and it appears that many of the stars are. There seem to be a large number of natural sites in the Milky Way and beyond that can support intelligent living. Some of these intelligent creatures, if only outdoors, may grow from ships.

No foreign experts (yet?) Visited the Earth. This vivid chance of existence, with a lack of evidence for its existence, is called the Fermi paradox, named after the physicist Enrico Fermi who first described the controversy in 1950. This raises the question. : where is everyone?

In 1961, astronomer Francis Drake attempted to justify this question by developing a concept that would take into account all the important aspects associated with finding kingdoms in space and classifying the number of nations in the galaxy. It should be possible. Consider important factors such as the rating of new stars, how many planets on those new stars and with these adaptations can support life, how many planets support the wisdom of life, in in these nations. How many technologies can we find, and whether they might contact us here, and others.

The search for Extraterrestrial Intelligence

Scientists and radio astronomers have begun searching for external knowledge (SETI) in a logical manner. Many international organizations, including the SETI Institute and the SETI League, are using television to identify signals that may have been produced by intelligent living.

In 1995, the SETI Institute launched the Phoenix Program, which used many of the world’s largest radio components: the Green Bank radio telescope in West Virginia, USA; the Arecibo telescope in Puerto Rico; and Parkes radio station in NSW, Australia. Early in his career, the Phoenix Program was used in the Parkes telescope to detect the arrival of 202 stars as 155 light years. At the end of its work, Project Phoenix surveyed the total 800 ‘near’ (up to 240 light years) distances for signs of life. The project recognizes some voices, but no one can identify men.

These days, anyone can get involved in the search for things from knowledge outside their own computer. SETI home is a project run by the University of California using public computer computers to increase the amount of radio television information that can be explored.

While there is now excitement about sending crews to Mars, missions beyond the current Red Planet are at all impossible: distance and time travel include it is very large. But it will be possible to do all the research for life beyond the Earth to do some special research on the ship in sight and driving rovers. These tools can capture a lot of information and can be interpreted at a distance like Pluto, perhaps even beyond the sun. But living beyond the sun, the stars close to many light years, and even communications through electric waves (everything that travels at the speed of light) would be a message. one way.

While we may not have the technical knowledge very close to home, there is a chance we may still have the most convenient simple forms. Do we have neighbors beyond the world? Time will tell - and the search will continue.

In 1995, the SETI Institute started the Phoenix Project, using many of the world's most powerful radios: the Green Bank Radio Telescope in West Virginia, USA; RCBo Telescope in Puerto Rico; At the Parks Radio Telescope in NSW, Australia. At the beginning of its phase, Project Phoenix used the Parse Telescope to detect the arrival of stars from 202 suns to 155 light. As a result of the operation, the Phoenix project raised a total of 800 (near '(240 light years away) stars for living signs.

Nowadays, anyone can get involved in the pursuit of mental therapy through their own computer. SETI Home is a project run by the University of California that uses computers from the public to increase the number of radio and television broadcasts that can be considered.
