Web14 de jun. de 2013 · The paper, recently published in Astrophysical Journal, states that as gas spirals toward a black hole through a formation called an accretion disk, it heats up to roughly 10 million degrees Celsius. The temperature in the main body of the disk is roughly 2,000 times hotter than the sun and emits low-energy, or "soft," X-rays. WebHá 3 horas · Nine metres long and two metres wide, the mysterious corridor was first detected in 2016 thanks to muon imaging. Muon imaging is a non-invasive technique which uses cosmic ray particles, called muons, to see inside solid objects, detecting changes in density and composition, and therefore enabling scientists to create 3D models of their …

As the nature of radiation was not known and it was invisible to the eye He called it unknown (X) -rays. WebRadiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. in built or built in
