Nebula
This glowing nebula (cloud of gas and dust) is the Crescent Nebula.
It is so vast that our entire Solar System would fit inside it seven
times over. The nebula’s light comes from a super-heated star at its centre. Known as WR 136,
this star is 15 times heavier than our Sun and 250,000 times brighter. Its immense power
comes from its fuel – helium.192-193_Helium_DPS.indd 192 02/12/16 6:52 pm
