#Stephenson218 #LargestStar #RedHypergiant
In the vast dark, a star two thousand times bigger than our Sun may be dying right now. Its surface could reach past the orbit of Saturn. Its light takes nineteen thousand years to reach us. So when we look at it tonight, we are not looking at now. We are looking at the past, and what we see may already be gone.
We call it Stephenson 2-18. A star so massive that our entire Sun would look like a grain of dust beside it. A star cooler than a candle flame compared to most stars, yet more than four hundred thousand times brighter than our Sun.
Tonight, we travel there. We will watch it swell, shudder, and shed pieces of itself into space. We will meet the star that stole its crown, and the astronomer who found it by accident. We will ask what happens in the final years before a giant like this tears itself apart.
