This image from NASA / ESA Hubble Space Telescope has an impressive portrait of M1
A nebula like this is formed when the star in the center throws large amounts of material from the outer layers, leaving a spectacular cloud of gas and dust.
It is believed that a binary star system in the center of the bipolar nebula is capable of creating hourglasses or butterfly-like shapes like the one in this image.
This is because the material from the throwing star is pulled towards its posts, with the help of the companion, and creates the distinctive double-winged structure seen in nebulae such as M1-63.
