Since I was a young child Mars held a special fascination for me. It was so close and yet so faraway. I have never doubted that it once had advanced life and still has remnants of that life now. I am a dedicated member of the Mars Society,Norcal Mars Society National Space Society, Planetary Society, And the SETI Institute. I am a supporter of Explore Mars, Inc. I'm a great admirer of Elon Musk and SpaceX. I have a strong feeling that Space X will send a human to Mars first.
NASA Has Discovered A Potentially Habitable Sister Solar System
NASA Has Discovered a Potentially Habitable ‘Sister Solar System’
Recently, NASA researchers made a very significant discovery using the Spitzer Space Telescope. They discovered seven Earth-size planets that could potentially harbor life in a sister solar system. These planets have been found orbiting a tiny star named Trappist-1. Trappist-1 is named after the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile.
Trappist-1 is in the constellation Aquarius and is about 40 light-years or 235 trillion miles away from Earth. In cosmic terms, this star is quite close to home.
Researchers are very hopeful that they can find alien life on the planets of Trappist-1. Their research suggests that three of these planets have rocks and have Earth-like masses. Above all, surface temperatures at these planets range between 0 to 100°C (32 to 212°F). NASA is hopeful that some of these planets could have water and maybe even extraterrestrial life.
Thomas Zurbuchen, the Associate Administrator for the agency’s Science Mission Directorate in Washington, said, “This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life. Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”
