Astronomers Found the First Green Star. It's Eating Its Own Planets.

You have never seen a green star. Nobody has. Starlight mixes every color into white, so a star can't look green just by being the right temperature. But in October 2026, astronomers announced the first star in our galaxy that would look green to human eyes. It's a dead star, a white dwarf called WD J1330+6435, and its color comes from the remains of the planets it is eating. In this video: why stars have colors, what happens when stars die, how dead stars swallow their own planetary systems, the reddest star ever found, and what all of this means for the future of our Sun.
