Now it might appear a bit insane, but it wasn’t long back that we had no hard proof of planets being present outside our Solar System. The planets which are present outside our Solar System are known as Expoplanets and the discovery of these planets were not made before 1992. Many years, since its discovery, a thin stream of distant worlds was added to the exoplanet catalog.
Only during the last decade, taking the help of the retired Kepler Space Telescope, the pace of discovery has rapidly improved. In June, existence of around 4000 exoplanet was affirmed.
It’s a big leap in a single life span, and to observe just how far we’ve come in processing our view of the universe. NASA had shared a video visualization which has been developed with its data by science outreach project System Sounds. It displays when and where in the night sky all the known exoplanets were spotted.
Kepler went to sleep forever in 2018, but its bequest has been picked up by other astronomical telescope such as the Transiting Exoplanet Survey Satellite (TESS) that has already discovered more than 700 new planet candidates in its first year in space.
Next, the European Characterizing Exoplanets Satellite (CHEOPS) is going to be fired by the end of the year and NASA’s James Webb Space Telescope is scheduled to launch in 2021. Both space telescopes would be able to do more than just observe/ see exoplanets. Well, they might help to consider if conditions exist to support life upon their surfaces.
