Astronomers have discovered what may be the first genuinely green star, a white dwarf called WD J1330+6435 located about 326 light-years from Earth. This discovery was made after researchers found that some dead star white dwarfs can take on a green hue after accreting rocky material from orbiting planets. The white dwarf's atmosphere, enriched with calcium, lithium, and sodium, absorbs the orange part of the spectrum, leaving behind a green glow.
This makes WD J1330+6435 the first known green star, as no other star, living or dead, has been credibly reported as green. The findings were published in the journal RAS Techniques and Instruments.
