Rigel is the 5th Interstellar Object and the 2nd Late Stage Star obtained in The Beyond Bubble Universe, which can generate Stardust. (Unlocked at Rank 19, branching off of Polaris)
In-Game Description[]
"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."
Traits[]
Common[]
- Nuclear Powerhouse (Speed):
"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! (Payout):
"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."
Rare[]
- Late-Stage Star (Payout):
"Once a star’s core is weaned of hydrogen, it matures into a late-stage star. As before, mass dictates size, color, luminosity, and temperature. But now it also determines the manner of death—following a long, gradual decline or in a cataclysmic explosion?"
Epic[]
- Cosmology (Speed):
"The scientific study of the universe asks the very biggest questions. How did it form? What came before? How does it work? Is it infinite? Will it die? All the pieces we observe—comets, moons, planets, stars, galaxies, nebulae, and even voids—provide some answers."
- Dark Matter (Payout):
"Dark matter acts like a superhero. It’s everywhere in space and yet invisible. Its gravity distorts huge objects that we can see. It can even buttress a dwarf galaxy against annihilation by a giant one. The duo of dark matter and dark energy make up 95% of the universe."
- Dark Energy (Discount):
"Little is known about dark energy, except that it’s repulsive. Opposing gravity, this strange force causes matter to scatter rather than attract, pushing our universe to expand faster and faster. Dark energy makes up 68% of the universe’s mass-energy density."
Constellations[]
- Eridanus (1.5x Speed):
"Eridanus, The River, is the longest constellation in the sky. It starts near Rigel and twists and turns all the way to its brightest star, Achernar (“River’s End” in Arabic). It was named after Eridu, an early Sumerian city in the marshes of what is now southern Iraq."
- Orion (2x Speed):
"The hourglass shape of Orion, the Hunter, is so striking that the star pattern figures in many of the world’s oldest cultures, perhaps even those of early humans. It rises seasonally, visible north of the equator for half the year and south for the other half."
System Components[]
Stars[]
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 brightess as the 7th brightest star in the sky, even from 800 light years away. It is also the most well known blue supergiant.
Achievements[]
- Star Dust Everywhere (Rank 3):
"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."
- Betelguese Blowout (Rank 6):
"In the constellation Orion, Beteguese is the hunter’s blood-red shoulder opposite the blue knee marked by Rigel. Both supergiants are fusing heavy elements, but Betelguese is near death. It recently had a massive blowout and could go supernova within 10,000 years!"
