Space Telescopes, Exploding Stars, and Dark Energy

Most stars en d their lives in brilliant explosions known as supernova. These massive bur sts briefly outshine all the light from the galaxy wherein they occur. The past 20 years have been a “boom” period for supernovae with vast amounts of time and effort being invested in these objects. Not only are they importa nt for understanding the life of stars, but they can be used use as cosmolo gical probes to study what the Universe is made of and how it is growing. T his use has shown that the Universe is accelerating in its expansion, the s ubject of the 2011 Nobel Prize, and is being caused by dark energy which wi ll cause the end of the Universe. I will show how our understanding of thes e objects has been revolutionized using new techniques including the Kepler Space Telescope and Hubble, and now with TESS and JWST and what this means for the Universe.
