Description: Today three of NASA’s four Great Observatories continue to record the universe from above the Earth’s atmosphere. These three satellites cover a broad range of the electromagnetic spectrum. The most famous of the three, the Hubble Space Telescope, is primarily an optical observatory, while the Chandra X-ray Observatory captures highly-energetic X-ray photons and the Spitzer Space Telescope collects cool infrared photons. The electromagnetic synergy offered by these three telescopes becomes apparent when studying celestial objects that represent the late stages of a star’s life.  Towards the end of the life of a sun-like star copious amounts of enriched material is liberated into the universe. The material rushes away from the star while undergoing dynamic changes that give rise to optical, infrared, and X-ray emission. The high-resolution imaging offered by these space-based observatories provides breath-taking views and insight into the end state of sun-like stars. However, growing evidence, some of which is provided by these space-based observatories, challenges our long-held view on the fate of sun-like stars. What is the fate of our Sun? Will it expire with a whimper, or end in a spectacular fashion?
