In summary, M13 is a region in the Andromeda galaxy that has been extensively studied and is used as a reference point for other galaxies. Decoding M13 refers to analyzing its characteristics to gain a better understanding of its structure and evolution. Scientists use methods such as spectroscopy and photometry to decode M13 and have learned about its age, formation, and the distribution and evolution of stars within it. The general public can also assist in decoding M13 through citizen science projects, which helps to advance scientific research.

This was the picturesque message beamed to the M13 cluster by the Arecibo Observatory in 1974. Even having a knowledge about earthly things, I fail to recognise most of the information depicted. How do they believe that alien intelligent beings some 22,000 lightyears away could decode such information and communicate with us? :confused:
