Emission mechanisms from various astronomical sources such as black holes, neutron stars, active galactic nuclei, pulsar wind nebulae, etc. arise from complex physical processes and are challenging to understand. The precise nature of the emissions from such sources still poses deep challenges to astronomers. Polarimetry measurements add two more dimensions to the understanding, the degree of polarization and the angle of polarization and are thus a diagnostic tool for understanding emission processes from astronomical sources.
In a spectacular display of prowess, India reached new heights in 2023 with the successful soft landing of Chandrayaan-3 on the Moon’s south pole and the launch of India’s first solar mission, Aditya-L1.
The primary objective of Chandrayaan-3, the country’s first successful lunar landing mission, was to perform a soft landing near the south polar region of the Moon and conduct experiments using instruments mounted on the lander ‘Vikram’ and rover ‘Pragyan’.
