| Description: NGC7635, or the `Bubble Nebula', is a `planetary' nebula around an OB star
(the only other known example beign NGC6164/6165). The clear bubble shape comes from a shell of
material blown off the star by a very strong stellar wind. The visible bubble is actually only the
smallest of three bubbles surrounding the star and was blown around 900 years ago.
