Exploding Stars, Dark Energy, & the end of the Universe General Meeting

Wednesday, 6 February 2019 8:00 PM

Most stars end their lives in brilliant explosions known as a supernova. These massive bursts briefly outshine all the light from the galaxy wherein they occur. The past 15 years has been a “boom” period for supernovae with vast amounts of time and effort being invested in these objects. Not only are they important for understanding the life of stars, but they can be used use as cosmological probes to study what the Universe is made of and how it is growing. This use has shown that the Universe is accelerating in its expansion, the subject Dr Brad Tucker from ANU will show how our understanding of these objects has been revolutionised using new techniques including the Kepler Space Telescope and what this means for the Universe.
