  • India's space visual instrument AstroSat has recently successfully measured X-ray polarization from Cygnus X-1 black depth, a preliminary achievement in black hole studies.
  • Normal X-ray measurements capture just energy or intensity, while polarization characteristics provide details about the geometry and properties of the black hole.
  • The measurements were carried out with the Boron Sync Telluride Imager (CJDTI) onboard AstroSat, which is one of the five scientific instruments onboard AstroSat.
  • The data takes scientists closer to understanding the mechanism of radiation production in black hole sources.
  • This study links the hard X-ray radiation in Cygnus X-1 to a black hole jet, which is an open question in astronomy.
  • Polarization is a property carried by a photon that provides information about the close expansion of a black hole.
  • Measuring X-ray wavelengths is a difficult task, but it provides valuable information.
  • AstroSat, launched by the Indian Space Research Organisation (ISRO) in September 2015, is a potential study of this unique one.
  • Cygnus X-1, discovered four decades ago, is one of the first localized black hole systems in our planet.
  • This black hole, twenty times heavier than the Sun, is in a binary system with a superprobe star, forming a thin arrival disk.
