"The life of a mega-mass star is short and dazzling. Rigel A is a blue supergiant ruling over three main sequence stars. It’s young, just 8 million years old, and white hot. The star burns so brightly that it blinds Earth’s telescopes—even from 860 light years away."
Rigel has the power to fuse ever-heavier atoms: helium, carbon, oxygen, neon, silicon…all the way up to iron. The elements settle in onion-like layers by mass, the heaviest at the center. Blue supergiants cool and reheat during fuel transitions, even dipping into red.

Supernova!
Iron fusion takes more energy than the star can give. So when lighter fuel runs out, in less than a second, Rigel will collapse under its own immense gravity and implode. This supernova blast can create heavy elements like gold and uranium, scattered in the star dust.

Star Dust Everywhere
Elements created by supernova explosions disperse through the universe. Some atoms combine and regenerate as stars, which inevitably die, repeating the cycle. In that sense, all the atoms on Earth—even the ones in our bodies—are made of star dust.
Rigel Rank 3
Betelgeuse Blowout
In the constellation Orion, Betelgeuse is the hunter’s blood-red shoulder opposite the blue knee marked by Rigel. Both supergiants are fusing heavy elements, but Betelgeuse is near death. It recently had a massive blowout and could go supernova within 10,000 years!

Trivia[]
A photo of Rigel
The Rigel star system (β Orionis) in the southern constellation of Orion is made up of four stars (quadruple star system), Rigel A, Rigel Ba, Rigel Bb, and Rigel C. Of these only Rigel A is present in the game. This is a blue supergiant of spectral type B8Ia, while Rigel B and Rigel C are main sequence stars of spectral type B9V. The exact properties of Rigel Ba, Rigel Bb and Rigel C are poorly known. Rigel is known for its immense brightness as the 7th brightest star in the sky, even from 800 light years away. It is also the most well known blue supergiant.
