The article I read is talking about according to foreign media reports, a group of Dutch science Recent research shows after we equipped with a new type of telescope we can detect the signal of life in extrasolar planet.
"Despite even remove our nearest star beyond the sun are 4.2 light years away, however, the substance of life activities manifested to be detected in its atmosphere, this signal is called "biomarkers gas .
" The idea has emerged since the 1960s began, and now it will get the support to the latest telescope technology, the core idea of this new type of telescope is to use a relatively low-cost foundation flux collection of telescopes to achieve the atmosphere of the extrasolar planets and collect high-resolution observations of the oxygen signal. The paper on the study will be published in astrophysics journal magazine on February 20."
The article shows it is able to detect the life in a planet which is far away. Human science and technology are developing to the universe and the outside world. we want to find other planet which is habitable after that we will know that there are many planet in the universe is able for human to live, we can move there when the earth is in danger or something. The Asteroid, Aerolite, and many things happen in the space can destroy the human easily. If we can find another planet we can live, it is more safe for the human.
After we find the life signal outside of earth, it is also a good chance for us to exchange with them and promote our science and our knowledge
