  1. OUR UNIVERSE : AN EXPANDING MYSTERY Supratik Pal Indian Statistical Institute, Kolkata

  2. Meeeeeee…..

  3. Night Sky From New York

  4. Beyond Naked Eye: Telescopes

  5. Radio Telescope: Proud to be an Indian

  6. Eye in the Sky: Hubble Space Telescope

  7. Supernova Anisotropy Probe Wilkinson Microwave Anisotropy Probe

  8. Happy Birthday to our Universe: 13800000000 Years Ago

  9. The First Sky

  10. A Star is Born

  11. Brighter than Stars : Nebulae

  12. Our Galaxy Milky Way

  13. Cloud made of Hydrogen in our Galaxy

  14. Even what we can not see also exists

  15. Our Galaxy is one among Millions

  16. How far are They ? 4 Light Years = (300000 km/sec) X (4X365X24X60X60 sec) = 40000000000000 kilo-meters !!! Nearest Galaxy Our Galaxy

  17. To See the Unseen: Lens in the Sky

  18. To See the Unseen: Collision in the Sky

  19. Death of a Star: Supernova Explosion

  20. What do they tell us ? Age of the Universe = 13800000000 Years Size of our Universe = 13800000000 Light Years = 100000000000000000000000 kilo-meters !!! Why are they so important ?

  21. Universe is expanding at accelerated rate

  22. Huge Energy Still Unknown

  23. Cosmic Microwave Background Radiation

  24. The Cosmic Constituents: As of Now

  25. And miles to go • Dark energy or cosmological constant? • What is dark energy? • Why is cosmological constant so small? • What is dark matter? • Who governs fast expansion at the beginning? • How were stars, galaxies etc formed? • Gravitational waves: yes or no? • How to match precise observational data? • How to discriminate a model from others? • Many more…..

  26. Want to make it a career? Basic level ….. • Mathematical Methods • Classical Mechanics • Quantum Mechanics • Electrodynamics Advanced level ….. • General Relativity • Quantum Field Theory • Particle Physics • Computer Programming
