For years, NASA has been discovering and researching on a couple of earth-sized planets that may inhabit alien life. Recently, NASA has discovered not one but seven earth-size planets that are orbiting the dwarf star called Trappist-1 They’ve found out that one or more of the planets is at a suitable temperature to contain water, making them promising targets in the search for alien life. Although the planets are 40 light years away, scientists have compelling evidence of aliens existing in these exoplanets.

There are many possibilities and signs that can be shown on the exoplanets to prove there is alien life. Amaury says that, “Here, if life managed to thrive and releases gases similar to that we have on Earth, then we will know.” This research of extraterrestrial life is being thoroughly observed through the Hubble Space Telescope to next year, the James Webb Space Telescope will be put into use to peer at the infrared wavelengths of light, ideal for studying Trappist-1. As“ Even if life is not discovered in the planets, it is still valuable research as to what is keeping life from flourishing.

The Spitzer Space Telescope of NASA was the first to find out that seven planets existed around the star. All seven are very close to the dwarf star, circling more quickly than the planets in our solar system. The innermost completes an orbit in just 1.5 days. The farthest one completes an orbit in about 20 days. That makes the planetary system more like the moons of Jupiter than a larger planetary system like our solar system. Because the planets are so close to a cool star, their surfaces could be at the right temperatures to have water flow, considered one of the essential ingredients for life. If observations reveal oxygen, methane, ozone and carbon dioxide in a planet’s atmosphere, M, says that there is a 99 percent chance of life existing on the planet. There are many possibilities of life existing and it is only in a matter.

Research on these exoplanets has gotten humanity closer to discovering extraterrestrial life. The Trappist-1 planets could be the beginning of a whole new species that we have not yet discovered and maybe a chance for humanity to live on it in the future. Astronomers expect that a few decades of technological advances are needed befBut Seth , an astronomer at said.
