A study of NASA’s TESS (Transiting Exoplanet Survey Satellite) data on stellar pairs undergoing mutual eclipses has uncovered more than two dozen candidate exoplanets, or worlds beyond our solar system. This method allows the mission to locate planets it couldn’t otherwise detect.  To date, TESS has discovered 885 confirmed exoplanets and identified more than 7,900 candidates, nearly all found because the planets pass in front of their stars from our perspective. These events, called transits, produce a small, regular dip in the brightness of the planet’s host star. TESS also observes tens of thousands of eclipsing binary stars — two orbiting stars that alternately eclipse each other from our vantage point. Astronomers can detect the gravitational tug of exoplanets in these systems by carefully measuring the exact timing of many eclipses.…
