... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

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). ... Mysterious Wow! ...

... Since IRS 7 at the Galactic center was identified as a luminous red supergiant (Lebofsky et al. 1982), a lasting debate has been initiated whether the nucleus of the Milky Way galaxy had experienced a recent star formation episode. ... 1993). ... 1994). ... Tamblyn & Rieke (1993) and Schaerer (1994) proposed starburst models which would be able to account for a young stellar population at the Galactic center, although the origin of some peculiar hot stars still remains to be explained (Tamblyn et al...

... ATNF Colloquium . The Void Galaxy Survey - exploring the loneliest galaxies in the Universe . ... As the evolutionary timescale in voids is long and extreme processes related to high galaxy density (ram pressure and tidal stripping for example) presumably absent, voids are ideal pristine environments to study galaxy structure and evolution. ... I will address morphology, star formation properties, and gas content and make a comparison with similar size galaxies in other environments. ...

... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...
