New Delhi: On, July 14, the talk was held at Shivaji College while on July 15,
SPACE always wishes to outreach science for the public and as a part of our program Centre for Student Excellence in Astronomy and Space Sciences, SPACE tries to provide students a platform for interaction with scientists and astronomers. Bal Bharati Public School, Pitampura runs a Centre for Student Excellence in Astronomy and Space Sciences for the students, where they learn hands-on science as a part of this self-sustaining education model. As, the school acts as a Resource cum guide Centre, the school didn’t let this opportunity of a talk by Dr. Banerjee to let go, and the ninth standard students were quite enthusiastic about the whole talk.
Dr. Banerjee pursued his BSc. (Physics) from St. Xavier’s College, Kolkata and later did his MSc. (Theoretical Physics) from University of Calcutta, further on he did his PhD in Astrophysics from Indian Institute of Astrophysics Bangalore, and thesis in Magnetohydrodynamic phenomena in the solar atmosphere.
His major research interests lies in Solar Magnetohydrodynamics, Waves and oscillations in stellar atmosphere. Chromospheric and coronal heating, Solar
The talk by Dr. Banerjee focused on the outer atmosphere of the sun – called the corona – that has been observed during total solar eclipse for short periods (typically < 6 min), from as early as the eighteenth century. In the recent past, space-based instruments have permitted us to study the corona uninterruptedly. In spite of these developments, the dynamic corona and its high temperature (1-2 million K) are yet to be fully understood. It is conjectured that their dynamic nature and associated energetic events are possible reasons behind the high temperature. In order to study these in detail, a visible emission line space solar coronagraph is being proposed as a payload under the small-satellite programme of the Indian Space Research Organisation. The satellite is named as Aditya-1 where ‘Aditya’ means ‘sun’. Everyone is excited for Aditya 1 after the Chandrayan, as ‘Aditya Mission’ would be the most exclusive mission which would take pictures of the sun at the speed of three frames per second as compared to the present speed of satellite images of the sun being one frame per eighteen minutes.
Dr. Banerjee also showed slides of the highest observatory facilities in India and a proposed observatory site at the Pangong Lake in Leh. SPACE eagerly looks forward to arrange such talks in future with passionate physicists and astronomers like these.
