The Imaging X-ray Polarimetry Explorer (IXPE) is a space observatory developed by NASA in collaboration with the Italian Space Agency, dedicated to measuring the polarization of X-rays coming from cosmic sources such as black holes, neutron stars, and supernova remnants. Launched in December 2021, IXPE is equipped with three identical telescopes that have detectors capable of not only capturing X-rays but also determining the direction and degree of polarization of these rays. This capability allows scientists to study the physics of extreme environments where gravitational, electric, and magnetic fields are at their limits. By analyzing how X-rays are polarized when they are emitted from or scattered by such high-energy regions, IXPE provides new insights into the structure and behavior of cosmic objects, offering a deeper understanding of the universe’s most energetic phenomena.
