I will summarize measurements related to the cosmic extragalactic background or cosmic light throughout the electromagnetic spectrum from gamma-rays to radio. The background is generated by cosmic microwave background photons at radio wavelengths, direct and thermal dust emission from stars and galaxies in the optical and infrared, and emission associated with blackholes in the UV and X- rays. I will discuss my group's research program that aims to improve our understanding of the cosmic infrared background. With careful measurements we are now able to separate the total background light to emission from point sources including galaxies in the distant universe, diffuse emission between galaxies, and foreground emission in our Galaxy, such as dust-scattered star light. I will present results from a NASA-funded sounding rocket experiment (CIBER), Hubble Space Telescope, and the Spitzer Space Telescope.
