There has been some planets that have been tested to see if we can live on it. scientist conduct a series of experiment to test if there’s life on other planets so we can live on. Most planets are not passing the experiments that scientist conduct. How do scientist determine if there is life on other planets.NASA Members are certain that there is life on mars and we can live on it but need more test and there is a planet called planet nine and we can live on it if we ever find it.First, NASA Found a solar system called Kepler-186 system, in the system Kepler NASA found a planet like earth, its size is about the same. NAZA named it Kepler-186f. With NASA’s “Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet”(NASA 2014)The moment that NASA found a solar system named Kepler-186f they claimed that they might have found a planet mostly identical to earth. “”We know of just one planet where life exists — Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth,” said Elisa Quintana, research scientist at the SETI Institute at NASA’s Ames Research Center in Moffett Field, Calif” (NASA 2014) .When NASA tries to find life on other planets they focus on one thing and that is if the other planets mimics earth.Also, The new test of life on other planets allow us to create experiments that allow us to understand weather we can or can’t live on other planets , “The test uses a liquid-based technique known as capillary electrophoresis to separate a mixture of organic molecules into its components. It was designed specifically to analyze for amino acids, the structural building blocks of all life on Earth”(Greicius 2017). NASA uses Capillary Electrophoresis which is a liquid-based technique in order to separate a mixture of organic molecules into its components.According to a NASA scientist ” The method is 10,000 times more sensitive than current methods employed by spacecraft like NASA’s Mars Curiosity rover, according to a new study published in Analytical Chemistry.” The study was carried out by researchers from NASA’s Jet Propulsion Laboratory, Pasadena, California. NASA claims that this specific experiment helped them alot to tell them whether or not there is life on other planets and if it passes then it is a likely place for humans to live on.Finally,NASA is testing the climate on other planets to see if its alright for us to live there.Before we go looking for life, we’re trying to figure out what kinds of planets could have a climate that’s conducive to life,” del Genio said. “We’re using the same climate models that we use to project 21st century climate change on Earth to do simulations of specific exoplanets that have been discovered, and hypothetical ones.”Scientist are using climate change to confirm if that planets is good for humans to live there. “Further, we should make sure we use the detailed knowledge of Earth. In particular, we should make sure of our discoveries on life in various environments on Earth, our knowledge of how our planet and its life have affected each other over Earth history, and our satellite observations of Earth’s climate.”NASA Scientists claims that they don’t only look for climate in a planet they are looking for other things that are very similar to earth.To conclude, Life on other planets are possible and NASA scientist are testing many things on other planets to see if there is life on other planets.it is very likely that there can be at least a planet that can mimic earth.Although scientist are doing experiments on other planets and is taking a long time sooner or later we will have NASA confirm a planets that is very similar to earth.
