NASA’s new telescope known as TESS(Transiting Exoplanet Survey Satellite) a planet-hunting orbital telescope designed to detect worlds beyond our solar system have discovered two new Earth-like planets this week five months after its launch which are at least 49 light years away from us.
TESS(Transiting Exoplanet Survey Satellite) from NASA is on a two-year Mission to expand astronomers’ known knowledge of exoplanets, planets circling distant stars. The expenditure on this mission is roughly around $337 Million.
TESS Deputy Science Director Sara Seager told the news agency how those two planets are too hot to support life but they expect many more such discoveries. “We will have to wait and see what else TESS discovers,”.
TESS is designed to build similar to its predecessor, the Kepler space telescope of NASA, which discovered the around 3,700 exoplanets in its lifetime of 20 years and is currently running out of fuel.
NASA expects to pinpoint thousands more previously unknown worlds with the help of TESS and perhaps hundreds of them Earth-sized or “super-Earth” sized planets in their list.
TESS is loaded With four special purpose cameras, it uses a detection method called transit photometry, which helps to look for periodic dips in the visible light of stars caused by planets passing and help in detecting the planets circling around the star.
Two new planets in solar systems are at least 49 light-years away from earth and termed as Super Earth and Hot Earth as per their known environment. TESS will monitor the brightness of more than 500,000 stars during the two-year mission.
