Astronomers Just Found the First Green Star Ever Discovered—Right After It Swallowed Its Planets
Astronomers have discovered the first green star ever identified, a white dwarf located 280 light-years away that would appear genuinely green to human eyes. Researchers studying 150 white dwarfs found that dead stars can glow in unexpected colors like green, pink, purple, yellow, and cyan due to unusual chemical interactions in their dense atmospheres. Specifically, atmospheric sodium causes the rare green hue of the newly found stellar remnant. This discovery follows right after the star swallowed its planets, leading scientists to describe it as a cosmic zombie.

Astronomers Discover First Green Star After Swallowing Planets
Astronomers have discovered the first green star ever identified, a white dwarf located 280 light-years away that would appear genuinely green to human eyes. Researchers studying 150 white dwarfs found that dead stars can glow in unexpected colors like green, pink, purple, yellow, and cyan due to unusual chemical interactions in their dense atmospheres. Specifically, atmospheric sodium causes the rare green hue of the newly found stellar remnant. This discovery follows right after the star swallowed its planets, leading scientists to describe it as a cosmic zombie.
Why it matters
White dwarfs are dense stellar remnants that form after stars run out of fuel. Traditional astronomical understanding held that these dead stars did not display such a vivid spectrum of colors to human vision. This surprising survey of white dwarfs updates how scientists view stellar remnants and chemical compositions in deep space.
What is confirmed
- Astronomers discovered the first green star, which is a white dwarf located 280 light-years away.
- The green color of the star is caused by atmospheric sodium.
- Researchers found that white dwarfs can also glow in pink, purple, yellow, and cyan due to unusual chemical interactions in their dense atmospheres.
- The findings are part of a survey examining 150 white dwarf stars.
Still unconfirmed
- The green star was discovered right after it swallowed its planets, leading to descriptions of it as a cosmic zombie.
What to watch next
- Further analysis of the chemical interactions causing unexpected colors in white dwarf atmospheres
- Additional surveys examining the frequency of green, pink, and purple white dwarfs
