Pulsars are magnetized spinning neutron stars that emit a beam of radiation. Since the first pulsar was discovered in 1967, thousands have been detected since, and they continue to be one of the most interesting objects in the sky. In this talk, Nikhil Mahajan will go over the history of pulsar astronomy, the reasons why we care about pulsars, and of course, what pulsars really are. Hopefully, this talk will leave you with an understanding of what current pulsar research is all about, and what it may lead to in the future.

Almost a century ago, Edwin Hubble discovered that galaxies appear to be moving away from us and that farther galaxies moved at faster rates. This discovery revolutionized our view of the Universe and started the field of modern cosmology. Ever since, astronomers have been trying to better measure the expansion of the Universe, the Hubble constant, using numerous standard candles.

Enjoy and learn about the night sky through an engaging presentation delivered by an astronomer. Learn about history, mythology and how to identify star constellations overhead.
