This logo is for the Cosmic Evolution Early Release Science (CEERS) Survey, a research group working on the Hubble Space Telescope, and will soon be utilizing the new James Webb Space Telescope as well, to study the oldest galaxies in the universe and understand how galaxies evolve over time.
I try to give as comprehensive of instructions as possible when handing logo files off to a non-designer. In cases like this, when "one" logo ends up being 30 different files, I do my best to make sure my clients can navigate what file to use when, and how to use them. This PDF walks the client through: the logo variations, the different color modes, the different file types, and "what not to do" usage examples.
