Spindle Galaxy NGC3115



Object Data
Description This edge-on disk galaxy's most noticeable feature is its complete lack of any dark or obscuring dust lanes. Also notable is the relatively large central bulge. This apparent shape has given it the nickname of the "Spindle Galaxy". Through a small telescope, it looks more like a simple oval lump of light rather than a spindle. Although it is currently classified as a Lenticular Spiral (S0), if the disk was not perfectly edge on to us, it would likely be classified as an elliptical.
