This is more than ten times longer than any observed episode of a star's death by black hole.
Astronomers have detected a giant black hole that's taken a record-breaking decade to devour a star.
Researchers made the discovery using data from NASA's Chandra X-ray Observatory, according to a release.
Researchers said this "food fest" is taking place in a galaxy 1.8 billion light-years from Earth.
University of New Hampshire scientist Dacheng Lin, who led the study, said this so-called black hole feeding frenzies have been observed since the 1990s. But those observed by scientists have lasted just a year, whereas this one has reached a record-breaking 11 years -- and it's still not done.
Lin and his team used data from three orbiting X-ray telescopes including NASA's Chandra X-ray Observatory to study this black hole's "eating habits."
X-ray flares erupt when a star gets swallowed by a black hole and cooked at millions of degrees.
