Over the last couple of weeks I have been writing about the Cosmic Microwave Background, as this month of July marks the 50th anniversary since the paper announcing its discovery was published. In this blog here I showed the original 1948 paper in which Ralph Alpher and Robert Hermann predicted its existence, and in this blog here, I re-posted something that I had written back in April 2013, before I had started research for the book I have published on the CMB.
Today I had been planning to write about its accidental discovery by Bell Labs astronomers Arno Penzias and Robert Wilson, but on Thursday of last week I had the following article published in The Conversation, if you follow this link you can read the original article. This article obviates the need for me to blog about the history of the discovery, you may as well just read it in The Conversation.
However, what is contained in this article is a summary of an even-more fascinating story, which you can read about in all its wonderful detail in my book, which can be bought directly from Springer, or from other booksellers such as Amazon.
To finish up this series on the CMB and its discovery, next week I will write about the Penzias and Wilson paper, and the accompanying paper by Robert Dicke and his Princeton team which attempted to explain the observation that Penzias and Wilson had made.
