Do you ever wonder about what's beyond our solar system. During our childhood we might have dreamed about the life beyond our planet a lot. Scientists are working hard to give a life to our dream. The search for the exoplanets had begun already in the late 20th century. Yes, We human begun to search for our next home. Obviously we all know the reason for this. Because we already exploited the wealth of this earth. This would be the result of our next home too. Let us discuss about this exploitation process later. Now, the real concern is how this expedition happens? and who is actually carrying out this?
Answer for these questions may be simple but it is a very long history. In 1917, scientists first begun to talk about this exoplanet discovery. They came up with so many ideas, but ultimately it ended up with using a telescope to view outside our solar system. HARPS (High Accuracy Radial Velocity Planet Searcher) was the first used spectroscope to find the exoplanet. It was installed in 2004 by ESO. After few years NASA introduced a even more accurate telescope to find the exoplanets. This telescope is called as Kepler Space Telescope, which is used by NASA till now. Both HARPS and Kepler Telescope used to find so many exoplanets. But the existence of life form in those planets are not yet confirmed by both the organisations. There are totally 3,758 exoplanets were discovered till now. 51 Pegasi B was the first ever exoplanet discovered in 1995. Which belongs to Pegasi 51 star.
Recently NASA launched TESS (Transiting Exoplanet Surveillance System ) Exploration program to find a new home humans. This TESS will look around the brightest star and search for the planets with suitable condition for humans to live there.
There are few factors which determine the presence of life forms in a planet. The first and foremost is the water and atmosphere, some planets may be rocky and some may be gas giants and ice vendors. But in order to meet the conditions that humans need is very important. We need all these is in a correct proportion. Humans can withstand roughly -9 degree F to 256 degree F. If the temperature exceeds this range we can't survive. So, temperature is also a deciding factor. We always rely on nature for everything but we are not ready to do anything worth relying on it.
There some private space agencies planning to take humans to moon as a vacation trip. If that happens we will definitely ruin our natural satellite. The exoplanets discovery is started because we humans know that we are not good at house keeping. We begun to loot our land for sake of technology and money and this journey will continue towards our very own end............
