    Popular Talks on 21st June 2020 during the eclipse.

    IIA Public Outreach Talk -1

    Speaker: Prof. Ravinder Banyal

    Title : Solar Eclipse: A Date with Celestial Light and Shadow Play

    Abstract: Eclipses are rare and dramatic celestial events. A solar eclipse is set to occur on 21st June, 2020. While the eclipse will be partly visible from most part of India, people in North will be able to get the better glimpse of annularity – where moon will obscure the central disk of the Sun, leaving a thin annular region around forming a spectacular “ring of fire”. In this talk, the speaker will explain the importance of eclipses, why they happen and how to view the Sun safely during the eclipse.

    IIA Public Outreach Talk -2

    Speaker: P.K.Mahesh,
    Engineer F & Head, Systems Engineering Group

    Title : Instruments for observing the sun-Siderostats, Heliostats and Coelostats

    Abstract: The aim of this talk is to provide details of one type of instrument used to observe the sun, the one using plane mirrors and lenses. There are 3 types of such equipment. The difference between them will be detailed.

    To the Moon and Beyond

    A Neil Armstrong Retrospective and Perspective


    Possibly the most iconic quote of the 20th century was from Neil Armstrong: "That's one small step for a man, one giant leap for mankind." Watched by 600 million people, that small step was responsible for many people choosing a career in the sciences. As President Obama said: "Neil Armstrong was a hero not just of his time, but of all time. Thank you, Neil, for showing us the power of one small step." The 1960s were a heady time for space flight. Sputnik had ignited the Space Race, John F. Kennedy made his historic speech: "... the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." There were expectations, fed by the Golden Age writers of science fiction, that we would have colonies, if not fully fledged cities on Mars and even Ganymede. 50 years later, only 12 men have ever walked on the Moon. Four are still alive, with the youngest being Charles Duke (83 years old). I will describe the achievements of the manned space program over the last 50 years, with a special focus on the Apollo program and prospects for the future.


    Title : The Magnetic Universe - Deciphering the Invisible


    Magnets are ubiquitous in our lives. Starting from the use of magnetic compasses to aid navigation until the advent of GPS, magnets are everywhere - in credit cards to smartphones and computers. Indeed, the entire Universe seems to be permeated with magnetic fields with different astrophysical systems like planets, stars, galaxies and galaxy clusters hosting fields of varied strengths. While stars and galaxies can be seen directly by the light they emit, cosmic magnetism is invisible to our eyes. However, astronomers can discover their presence through the detection of radiation which exhibits the effects of magnetic fields. This has ushered in a new era to explore one of the last unexplored features of the Universe. In this talk, we will set sail on a riveting journey to seek answers as to how these cosmic magnets originated, when did they first come into existence and most significantly, how have they survived through to this day.
