What are some notable discoveries of retired NASA telescope?
NASA planet-hunting Kepler space telescope, which retired on Tuesday after running out of fuel, has discovered over 2,600 exoplanets and surveyed over 5,00,000 stars. It has found that planet Kepler-16b witnesses two sunsets due to its twin-star-system, while five planets in Kepler-444 are twice the age of our sun. Kepler has also caught a dead star vapourising its own planet.
