However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ...

News & Views There seems to be something very healthy about astronomical research when, under the same cover, an event which took place in 1333 AD (Leonid bursts as a resonance meteoroid component from Comet Temple/Tuttle) is discussed followed by a paper on how we might more effectively search for extraterrestrial intelligence (in the optical). In this issue we also have a further paper on young clusters (Praesepe) and the low end of the stellar mass function (see IAJ , 1999, 26(1), 17). ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
