Astrophiz72-Dr Brad Tucker-Supernova Space Detective

Astrophiz 72: Dr Brad Tucker ~ SUPERnova Space Detective Brad tells us about his research using the Keppler Space Telescope and how its successor TESS is generating great science already. He tells us how astrophysicists use a variety of tools to measure how the universe is changing over time. He explains how remote observing has radically changed the way astronomy is done around the world and how we now use telescopes with 100 times the light collecting area of the Hubble telescope and use lasers to correct for disturbances in the atmosphere. If you thought your 12 inch Dobbie was big, and it is, consider that researchers are now building telescopes with 25 to 30 metre mirrors. In our regular segment for astrophotographers and observers, Dr Ian 'Astroblog’ Musgrave presents ‘What’s Up Doc?’. In this episode he tells us about the planets, the geminid meteor shower and comets currently visible to the naked eye. In the News: .1. Dr Brad Tucker & team find a unique Type 1A Supernova. .2.
