PASIPHAE Project – UPSC Prelims

By /
  • Polar-Areas Stellar-Imaging in Polarisation High-Accuracy Experiment (PASIPHAE) is an international collaborative sky surveying project.
  • Aim: To study the polarisation in the light coming from millions of stars.
  • Features:
    • The survey will use two high-tech optical polarimeters to observe the northern and southern skies, simultaneously.
    • This will help us focus on capturing starlight polarisation of very faint stars that are so far away that polarisation signals from there have not been systematically studied.
    • The distances to these stars will be obtained from measurements of the GAIA satellite.
