Take a quick look at why this discovery is turning heads in the astronomy world:

  • Scientists have found the first known 6-star system – TYC 7037-89-1 – where every star regularly eclipses its partner, creating a cosmic light show 1,900 lightyears away.
  • The system is made up of three pairs of 'eclipsing binaries', meaning each pair’s stars take turns passing in front of one another, dimming the system’s brightness from Earth.
  • These regular eclipses let astronomers precisely measure the stars’ sizes, masses and temperatures, offering new clues about how such complex systems form and evolve.
  • NASA’s TESS mission sifted through 80 million stars to find this rare gem, highlighting the power of modern space telescopes in revealing the Universe’s hidden wonders.
  • Studying how these stars have grown so similar could help scientists understand star formation and the life cycles of multiple-star systems.
