Source sentences:
text: But massive stars, many times larger than our own sun, may create a supernova when their core's fusion process runs out of fuel.
text: Because only massive, short-lived stars produce supernovae, the Sun must have formed in a large star-forming region that produced massive stars, possibly similar to the Orion Nebula.
text: Stars with masses lower than 8 M ☉ are thought to be too small to produce supernova explosions, and end their lives by producing a planetary nebula instead, while a star heavier than 12 M ☉ would have produced a nebula with a different chemical composition from that observed in the Crab Nebula.
