NASA’s TESS spacecraft is finding hundreds of exoplanets – and is poised to find thousands more
Within just 50 light-years from Earth, there are about 1,560 stars, likely orbited by several thousand planets. About a thousand of these extrasolar planets—known as exoplanets—may be rocky and have a composition similar to Earth’s. Some may even harbor life. Over 99% of these alien worlds remain undiscovered—but this is about to change.
