Dr. Fujioka stated that the pellet was turned into "… a source of [immensely powerful] x-rays similar to those from an accretion disk around a black hole.” [ScienceNOW]
Because astronomers cannot see a black hole directly (because all electromagnetic radiation [light] is turned inward by the giant gravitational field generated by the extremely dense black hole), they are forced to analyze its accretion disk.
The accretion disk becomes visible in x-rays (one type of electromagnetic radiation, or light) when energy is generated by the immense gravitational field within a black hole.
Thus, the work by Dr. Fujioka and his colleagues will help scientists learn more about the processes in and around black holes.
The ScienceNOW article states, “By measuring the energy lost from the photoionization, the researchers could measure total energy emitted from the implosion and use it to improve their understanding of the behavior of x-rays emitted by accretion disks.”
You think you have a disaster recovery plan?
Think again. Most businesses only have PART of a DR plan - and this spells business disaster in the event of an IT disaster.
