... GALEX: The Andromeda Galaxy . ... A mere 2.5 million light-years away, the Andromeda Galaxy really is just next door as large galaxy's go. So close, and spanning some 260,000 light-years, it took 11 different image fields from the Galaxy Evolution Explorer (GALEX) satellite's telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light. ...

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). ...

Physical conditions of the interstellar medium in galaxies are closely linked to the ambient radiation field and the heating of dust grains. ... The KINGFISH profiles are well suited to examining trends of dust temperature Tdust and нІ because they span a factor of ~200 in the ISRF intensity heating the bulk of the dust mass, Umin. Results from fitting the profile SEDs suggest that, on average, Tdust, dust optical depth о„dust, and Umin decrease with radius. ...
