In a universe with a potentially infinite number of galaxies and planets, this might seem trivial.
However, the first ever exoplanet was only confirmed in 1992 and technological advancements have come a long way since.
The best way to search for exoplanets, as was the case in the latest discovery, is to look for their transits.
When a planet or some other object passes in front of a star, powerful space telescopes may be able to detect a minute dip in their brightness.
NASA’s TESS and Kepler telescopes have used this technique to great success, but there are some limitations.
