Astronomers have discovered the first-known “sextuply-eclipsing sextuple star system,” after a neural network flagged it up in data collected by NASA’s Transiting Exoplanet Survey Satellite (TESS).
The star system, codenamed TIC 168789840, is an oddball compared to its peers. Not only does it contain six suns, they’re split into three pairs of eclipsing binary stars. That means the suns in each pair, to an observer, pass directly in front of one another in their orbits. The stars in each pair are gravitationally bound to each other and to every other sun in their system, meaning each pair circ
