This is a color composite image made by Karen Gloria at Hopkins Observatory using a 6-inch refractor and a 512x512 element CCD detector. This is the famous Trifid Nebula, often photographed. It is a nice illustration of the combined effections of ionization and scattering caused by the large yield of blue and UV photons from newly formed massive stars.

... Bad Astronomy . ... A tidbit of news on the brown dwarf front came in this week. Regular readers may remember that brown dwarfs are objects that are intermediate in mass between a planet and a star . ... So this is even better evidence that brown dwarfs form like stars and not planets. Brown dwarfs may not turn out to be the 'missing link' between planets and stars the way some astronomers thought a few years ago, but they are providing clues on just how stars and planets do form. ...

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). ...
