Enigma: NGC55


This is a large member of the Sculptor Group of galaxies; but what are we seeing? Apparently, an edge-on view, but with the bright core to the W and only a fainter arm to the E? A Gendler image suggests the bright 'cigar' is the central core seen through an outer arm of blue stars. Several small 'knots' are likely OB clusters of activity. A possible stellar central nucleus is arrowed. Reference stars are noted in case we see a super nova! This galaxy is seen well in a 4in 'scope. Is NGC55 a barred spiral with only the E arm visible - the W one hidden from view?

  1. Yet again nowadays Neanderthal man creates good information in the London, uk media, as researchers state they have lastly unravelled his exclusive genome. Not amazingly, Big N carries on to be the prominent product in the "cave man" industry, forcing many copy cats. But just who was this reclusive guy and where did he come? crossword answers
