A collection of spacecraft have been observing stars, nebulae, and galaxies from one end of the electromagnetic spectrum to the other for many years. The images and data returned by these spacecraft have increased our knowledge about stars and stellar evolution and galactic structure and evolution. Data and images from a variety of spacecraft such as Spitzer, Chandra, and others on variable stars, nebulae, galaxy clusters, supermassive black holes, and more, are reviewed in this presentation.
