NASA has created a map showing as many as 4,000 planets from outside the solar system as you know it. This is a breakthrough, as it was only a while ago that there was no concrete evidence of any planet existing beyond the region.
The first confirmed discovery of this kind of planet, known as an “exoplanet,” was made in 1992. In the last decade, with the aid of the Kepler Space Telescope, more and more exoplanets have been spotted, according to CNET.
After the telescope became defunct in 2018, observatories like the Transiting Exoplanet Survey Satellite took over and discovered many more celestial bodies. The 4,000th one was discovered in June this year.
Two new space telescopes, the European Characterizing Exoplanets Satellite (CHEOPS) and NASA’s James Webb Space Telescope, can soon be used in 2021. Their uses are significant as they can help to determine if any of those planets can support life. The next frontier in space travel might then be opened up.
