Source sentences:
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.
text: Stars greater than 8 solar masses (M ⊙ ) will likely end their lives in dramatic supernovae explosions, while planetary nebulae seemingly only occur at the end of the lives of intermediate and low mass stars between 0.8 M ⊙ to 8.0 M ⊙ .
text: All Wolf–Rayet stars end their lives from the Wolf–Rayet phase within a million years or so, but again it is difficult to identify those that are closest to core collapse.
text: There are also nebulae made from the outer layers of massive stars that ended their lives in an enormous explosion called a supernova.
text: However, not all stars end their lives as supernovae and there are several types of this phenomenon.
text: Although only a few stars per century in our Galaxy will end their lives in this spectacular way, these explosions are responsible for making all chemical elements heavier than iron in the Universe.
text: Smaller stars such as the sun end their lives as compact white dwarfs.
