Astronomers discover green star 280 light-years away; what makes it glow green

Astronomers have discovered an intriguing white dwarf star designated WD J1330+6435, nestled within the Draco constellation. Its striking green hue arises from the interaction of sodium and helium particles in its atmosphere. This celestial body lies about 280 light-years from Earth, presenting itself as it was 280 years ago. With a surface temperature nearing 4,000 degrees Celsius, its dimensions are comparable to that of our planet.
