2. Cosmic infrared background - Wikipedia

   en.wikipedia.org/wiki/Cosmic_infrared_background

   Nuclear fusion takes place inside the stars, and we can really see this light redshifted: this is the main source of the cosmic ultraviolet- and visual background. However, a significant amount of this starlight is not observed directly. Dust in the host galaxies can absorb it and re-emit it in the infrared, contributing to the CIB.

   The diffuse extragalactic background light (EBL) is all the accumulated radiation in the universe due to star formation processes, plus a contribution from active galactic nuclei (AGNs). [1] This radiation covers almost all wavelengths of the electromagnetic spectrum , except the microwave, which is dominated by the primordial cosmic microwave ...

   en.wikipedia.org/wiki/List_of_space_telescopes

   Microwave space telescopes have primarily been used to measure cosmological parameters from the Cosmic Microwave Background. They also measure synchrotron radiation, free-free emission and spinning dust from the Milky Way Galaxy, as well as extragalactic compact sources and galaxy clusters through the Sunyaev-Zel'dovich effect.
