Imaging X-ray Polarimetry Explorer

Measuring the cosmos to learn about space extreme environments

The Imaging X-ray Polarimetry Explorer (IXPE) mission is flying three space telescopes with cameras capable of measuring the polarization of the cosmic X-rays from black holes, neutron stars, and pulsars. This will allow scientists to answer fundamental questions about turbulent and extreme space environments where gravitational, electric, and magnetic fields are at their limits.
