    This is a good chance to remind astro followers that the #CosmicMicrowaveBackground was discovered as a blackbody background temperature @2.3 K by McKellar [1] in *1941* using Adams' observations [2] of #DiffuseInterstellarBands (#DIBS).

    With the ADS+Wikipedia, there's no need to blindly repeat the popular textbook myth that Penzias & Wilson discovered the #CMB; they only *re*-discovered it.
