  • In spring 2010, NASA’s orbiting Galaxy Evolution Explorer and the ground-based Pan-STARRS telescope observed a suspicious brightening around a supermassive black hole parked more than 2 billion light-years from Earth
  • Over the next few months, the flare continued increasing in brightness — then it dimmed
  • Scientists now suggest that the light show was evidence of the black hole PS1-10jh shredding a star that wandered too close

  • analysis presented online May 2 in Nature indicates that at the time of engulfment, the star was just a helium-rich core, the remainder of a former red giant
  • The black hole
  • weighing about 3 million solar masses, had probably already snacked on the star’s outer layers during a previous close encounter.
  • the black hole spat some of the stellar material into space
  • followed elongated orbits that eventually dumped them back into the black hole, producing the observed, months-long flare.
  • Such disruption events are rare, thought to occur only once every 10,000 years per galaxy
  • can help astronomers spot otherwise hidden black holes.

  • C class asteroids: They are found in the Earth’s outer belt and are darker and more carbonaceous than the ones found in the S class.
  • S class asteroids: They are found in the Earth’s inner belt, closer to Mars and are composed of mostly stone and iron.
