What Happened
NASA's TESS spacecraft has discovered a new exoplanet, utilizing a method based on Einstein's theory of gravity. The discovery was made through gravitational microlensing, a technique that observes the bending of light from a distant star by the gravity of an intervening object, such as a planet.
This exoplanet was not the primary target of the TESS mission, which is designed to search for planets transiting, or passing in front of, their host stars. Instead, the planet was found incidentally within the data collected by the spacecraft, highlighting an unexpected capability of the mission.
The discovery demonstrates the versatility of TESS's observational data and its potential to reveal celestial bodies through methods beyond its initial design parameters. The use of gravitational microlensing, a concept rooted in Einstein's general theory of relativity, underscores the scientific principles employed in modern astronomical research.
