Scientists have made yet another break through by discovering a new star system which can support life and is 39 light years away. The entire planet system has shown some positive signs of water presence and revolves around a dwarf star called Trappist-1. They claim that 3 of the 7 planets might as well have life already present on them which shows they have the basic biological conditions to support the growth of biological life. In a decade or so, scientists will have some solid information or proof about presence of life here. They are amazed because they have never found such planets that are so earth like in terms of size and atmosphere.
New Start System
Scientists claim that out of the 7, 3 of the planets might have water bodies like ocean and life present already. They are studying all 7 I detail and expect to get more concrete facts and figures in the years to come. This planet system was discovered using telescopes which were fitted on ground and space.
The habitable planets are those that are situated in the middle of the innermost and outermost. The situation is ideal for such atmospheric conditions that support biological growth and sustainability.
Somewhat like Earth, this planet gets less energy than earth. These planets are however, tidally locked i.e. one side always has day and the other always has night. The possibility of presence of life is indicated by certain chemical signals which can be detected through special telescopes.
A New World
Sending robots and human to these planets is still a question mark. Scientists are still waiting for a breakthrough in science that could make it possible for at least robots to be sent 39 light years away. Another scientist Ignas Snellen says that these planets are close to earth but still not too close to send humans. It might take hundreds of thousands of years.
But this discovery is meaningful. It means that there might be other habitable planets in the Milky Way. Scientists were looking everywhere for clues of planets with life or chances of growth of biological beings, and now they have some direction where to look at.
Trappist-1 is brighter than sun, smaller, red in color and cooler. Such stars are common in our galaxy but now visible through the naked eye, only through a powerful telescope. It was discovered back in 2016. Scientists continued to scan whole system for any transits, using multiple telescopes from various locations, throughout the globe. 34 clear transits were identified which helped scientists to find 4 planets circling the Trappist-1.
A lot has yet to be done to explore these planets. Gillon and his fellow scientists have a lot on their plate already with regard to observing these planets, specially the one which is the outermost. The next step, according to Gillon is, using various telescopes from around the globe once again to determine any signs of life present on these new plants. Keep your fingers crossed.
