DESCRIPTION:*Probing Exoplanetary Atmospheres with JWST (Prof. Nikku Madhu
 sudhan)*\n\nThe discoveries of thousands of extrasolar planets have reveal
 ed an astonishing diversity in their physical characteristics - orbital pr
 operties\, masses\, radii\, temperatures\, and host stars. Exoplanets know
 n today range from super Jupiters to Earth-size rocky planets over a wide 
 range of temperatures\, including several in the habitable zones of their 
 host stars. The JWST presents an unprecedented opportunity for remote sens
 ing of exoplanetary atmospheres\, probing the diversity of their atmospher
 ic properties and a range of physical and chemical processes. I will prese
 nt an overview of the major questions JWST is expected to address in this 
 area\, with implications for our understanding of planetary atmospheric pr
 ocesses\, formation and evolution\, and the possibility of life elsewhere.
  I will discuss some early results\, ongoing developments\, and future dir
 ections.\n\n*A First Glimpse Of Webb's Revolution For Our Understanding Of
  Galaxy Formation (Prof. Roberto Maiolino)*\n\nThe successful launch\, dep
 loyment and commissioning of the James Webb Space Telescope\, about one ye
 ar ago\, has opened a new era in astronomy and astrophysics. Indeed\, in s
 ome infrared spectral bands\, Webb’s sensitivity is up to three orders o
 f magnitude higher than previous facilities. Such a huge leap in sensitivi
 ty has happened very rarely in the history of astronomy and\, even more br
 oadly\, in the history of science. The major jump in sensitivity\, along w
 ith the much sharper images delivered by JWST\, are of paramount importanc
 e to make progress in our understanding of the early phases of galaxy form
 ation in the distant Universe\, in particular to explore the first generat
 ions of stars and the first black holes.\n\nThe first observations release
 d by this fantastic observatory have not disappointed\, by delivering seve
 ral unexpected results.\n\nI will give an overview of the early\, exciting
  findings from the Webb telescope by focusing on the new results on distan
 t primeval galaxies. I will show that some of these discoveries are indeed
  changing our understanding of galaxy formation in the early Universe and 
 of their subsequent evolution and trasformation across the cosmic epochs.\
 n\n*From Black Hole Singularities to Conformal Cyclic Cosmology (Prof. Rog
 er Penrose)*\n\nProf. Penrose will talk about how his thinking about black
  holes developed\, after many years\, into his theory of CCC\, a radical n
 ew cosmology with strong observational consequences.\n\n
