  • Astronomers have observed for the first time a phenomenon, called, “cosmic cannibalism”.
  • In this, a dead star is sucking in debris from both the inner and outer reaches of its planetary system.
  • A white dwarf is formed when a low-mass star like our sun exhausts most of its nuclear fuel.
  • It is usually very dense, dim and about the size of a planet.
  • It is the last observable stage of evolution for low- and medium-mass stars.
