Henize 70 (N70) is a faint[7] emission nebula[8] and superbubble[5][4][9][10][11][12][13][14][15][16][17][18][19][20][21][excessive citations] 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.

[8] A paper published in 1978 proposed that the formations of Henize 70 and other emission nebulae could be due to stellar winds.

[22] Later in 1981, a scientific article mentioned a higher likeliness of a supernova explosion forming the nebula instead of stellar winds.

[23] A 2014 study measured that Henize 70 featured high SII and Hα ratios, indicating that it is not a supernova remnant.
