Story summary

Astronomers observed V Sagittae, a binary star system 10,000 light-years away, experiencing extreme stellar cannibalism.
A white dwarf siphons hydrogen from its larger companion, igniting thermonuclear burning and increasing brightness.
The system orbits every 12.3 hours and has puzzled scientists since 1902.
A luminous gas ring indicates instability and the potential for a visible nova explosion.
Researchers caution that a supernova may occur if the stars collide or the white dwarf accumulates too much mass.
