    The images were captured by remote sensing payloads i.e. Solar Ultra-violet Imaging Telescope (SUIT) and Visible Emission Line Coronagraph (VELC), aboard Aditya-L1 spacecraft.

    • These images will help in studying solar flares, energy distribution, sun spot, understanding and predicting space weather, monitoring solar activity and UV radiation over a wide wavelength range. 

    About SUIT and VLEC

    • SUIT: To image Solar Photosphere and Chromosphere in near Ultra-violet (UV) and, to measure solar irradiance variations in near UV.
    • VELC: To study solar corona and dynamics of coronal mass ejections.

    About Aditya L-1

    • Launched in 2023, it is India’s first space mission to observe Sun from a halo orbit around the Lagrange point 1 (L1) of Sun-Earth system, which is about 1.5 million km from Earth.
    • It was launched by Polar Satellite Launch Vehicle (PSLV) XL (PSLV-C57) with 7 payloads on board

    Significance of Aditya L1

    • To understand Coronal heating and solar wind acceleration. 
    • Observe in-situ particle and plasma environment providing data for study of particle dynamics from Sun

    Other solar missions 

    • NASA’s Parker Solar Probe; European Space Agency’s Solar and Heliospheric Observatory; China’s Kuafu-1 solar probe etc.

    About Lagrange point (L1)

    • At Lagrange points, gravitational pull of two large masses (like Sun and Earth) precisely equals centripetal force required for a small object to move with them.
    • L1 has advantage of continuously viewing Sun without any occultation/ eclipses.
    • There are five Lagrange points, three are unstable (L1, L2, L3- lie along the line connecting two large masses) and two are stable (L4, L5).
