Story summary
  • The European Southern Observatory's Very Large Telescope imaged the binary star system AFGL 4106, revealing two ageing stars shedding gas and dust to form an egg-shaped nebula.
  • The nebula's distortion likely results from the companion star's gravitational pull.
  • Most stars in our galaxy exist in binary systems, with up to 85% not solitary.
  • The findings in Astronomy & Astrophysics highlight how stellar partnerships affect stellar death.
