Exoplanet discovery: Watch to know more about inside world of Trappist-1 star and its orbiting planets

Firstpost  

Nasa’s Spitzer Space Telescope has found seven Earth like exoplanets in orbit around a single ultracool white dwarf star. Three of the planets were initially identified as the exoplanets most suitable for life as we know it on Earth, by an international team of astronomers last year. The weather on these worlds would be more extreme than those on Earth, with strong winds blowing from the day side to the night side, and extreme changes in temperature. An international team of astronomers have made available data-sets of over two decades of observations, in an effort to crowd source the discovery of new extra solar planets.
