Modern astronomy started four centuries ago with Galileo’s invention of the astronomical telescope. In the past century, astronomical observations using different wavelengths of electromagnetic waves revolutionised our understanding of the Cosmos. Recently, observations using subatomic particles such as neutrinos and cosmic rays also have emerged as powerful means of probing the Cosmos. The newest frontier of astronomy is observations of gravitational waves — the elusive ripples in spacetime predicted by Albert Einstein a century ago. This lecture will take a walk through the different frontiers of astronomy.
