Astronomers have found a white dwarf star 280 light-years away that appears green, caused by sodium interacting with helium in its dense atmosphere.
Astronomers have discovered a star that appears green, an unusual celestial sight that could change how scientists understand the colours of dying stars.
Astronomers discovered a white dwarf star called WD J1330+6435 that glows green, an extremely rare colour for a star, located 280 light-years away in the constellation Draco.
The green hue is caused by sodium interacting with helium under intense atmospheric pressure, altering the wavelengths of light the star absorbs, the study found.
The discovery suggests the chemical makeup of a dying star's atmosphere can produce colours far beyond the usual orange, white or blue, changing how scientists understand white dwarfs.
The study found that a white dwarf's chemical atmosphere can dramatically change the colour of light it emits, which researchers say could reshape how scientists classify dying stars.
