An international team of researchers investigating strange donuts-shaped clouds found near some gigantic black holes have determined that those clouds are cosmic remains from high-speed violent collisions between asteroids and planets.
The supermassive black holes are found in the central parts of most galaxies and nearly half are obscured by the dust clouds.
At this time astronomers do not fully understand how the dust clouds came into existence while they predict that they could be leftover fragments from asteroids and planets that collide with one another. If that theory is correct it would prove that central regions of galaxies not only contain black holes and starts but also asteroids and planets which were previously thought to only exist outside of those areas.
According to the CSMonitor:
The researchers' theory is inspired by the so-called zodiacal dust in our own solar system, which is known to originate from collisions between objects such as asteroids and comets. These rocky objects smash into one another at colossal speeds of more than 2 million miles per hour (over 3 million kilometers per hour), continuously shattering into fragments that eventually end up as microscopic dust, the astronomers said.
Researchers will publish their full set of findings in upcoming edition of the journal Monthly Notices of the Royal Astronomical Society.
The debate remains open regarding the exact nature of cosmic clouds that surround supermassive black holes, why do you think they exist?
