About this object
NGC 91 (Arp 65) is an unusual spiral galaxy in the constellation Pegasus.
It is classified as SAB(s)c(pec), which means that it is a spiral ("S") with a
central bar, not well developed ("AB"), where the arms start at the ends
of the bar (the "(s)"), and are few in number and quite open (the final
"c"). The "(pec)", or peculiar, features include the extended material
seen to the upper right (NW) in this image, as well as a second fainter trail
going to the bottom left (SE), which is only hinted at in this short
exposure. There are several other galaxies nearby, which may account
for its oddities (although not everyone thinks we can always blame
interactions for strange morphologies).
Location: 00 21 51.7 +22 24 01 (2000.0), distance: over 200 million light years,
size: perhaps 60000 light years across.
