The star HD 87643 shows beautiful extended nebula of gas and dust that reflects the light from it. The star's wind appears to have shaped the nebula, leaving bright, ragged tendrils of gas and dust. A careful investigation of these features seems to indicate that there are regular ejections of matter from the star every 15 to 50 years.
