Henize 70 (N70) is a faint[7] emission nebula[8] and superbubble[5] located in the Large Magellanic Cloud in the constellation of Dorado.
Henize 70 was first observed in 1950 in a survey of bright planetary nebulae. Based on appearance it was proposed that it might be a supernova remnant.[7] In 1956, it was added to a catalogue of Hα emission stars and nebulae by Karl Gordon Henize, where it was described as an emission nebula rather than a planetary nebula.[8]
