XPoSAT: How ISRO’s Black Hole Mission Will Script A ‘POEM’ In Space, And Why It Is Special

XPoSAT is special because it is the second spacecraft in the world which will study celestial bodies using polarimetric techniques, after NASA's Imaging X-Ray Polarimetry Explorer (IXPE). 

XPoSAT will analyse X-rays emitted by celestial bodies such as black holes, neutron stars, active galactic nuclei, and pulsar wind nebulae by measuring the beams of light in which the vibrations of electromagnetic waves are confined to one plane. Also, it will script a 'POEM' in space.

XPoSAT: The X-ray Polarimeter Satellite (XPoSAT), India's first mission to study black holes and neutron stars, is special for several reasons. XPoSAT is India's first dedicated polarimetry mission to study the dynamics of bright astronomical X-ray sources in extreme conditions, which means the spacecraft will analyse X-rays emitted by celestial bodies such as black holes, neutron stars, active galactic nuclei, and pulsar wind nebulae by measuring the beams of light in which the vibrations of
