National Aeronautics and Space Administration has discovered SEVEN planets which are similar in size of Earth, rocky and probably have ocean. Using a robotic telescope operated by Liverpool John Moores University. Six of the planets lie in TRAPPIST-1 which have a surface temperature zero to 100 degrees Celsius. Three of the planets out of these six planets have an ocean, so scientists state that anywhere on Earth you find water. Manager of NASA’s Spitzer Science Center at Caltech, California, Sean Carey said, “This is the most exciting discovery we had yet with the Spitzer telescope and its 14 years of operation”. He added Spitzer will follow up in the fall to further refine our understanding of these planets so that the James Webb Space Telescope can follow up”.
Three planets in the “habitable” zone where temperatures vary to permit surface oceans of liquid water. British astronomer Dr. Chris Copperwheat said, “The discovery of multiple rocky planets with surface temperatures which allow for liquid water make this amazing system an exciting future target in the search for life”. Astronomer at the University of Liege in Belgium, Michael Gillon said, “Three of the planets are in the so-called Goldilocks zones where liquid water could exist”. TRAPPIST-1 is a small star with 8 percent the mass of the sun and only slightly bigger than the planet Jupiter. Dr. Gillon added,” This is an amazing planetary system – not only because we have found so many planets, but because they are all surprisingly similar in size to the Earth”. The discovery founds the greatest number of habitable-zone planets found around the solar system.
