First Ever Green Star Discovered in Universe 326 Light-Years From Earth
- •Scientists at the University of Warwick have discovered the first green star in the universe, a white dwarf named WD J1330+6435 located 326 light-years away from Earth.
- •The star's unusual green color is caused by the presence of sodium, calcium, and lithium in its atmosphere as it consumes its own rocky planets.
- •This groundbreaking research challenges long-standing astronomical rules that stars and white dwarfs only emit colors strictly determined by their temperature.
- •Depending on their chemical composition, white dwarf stars can also display pink, purple, yellow, and pale blue colors due to extreme density and atmospheric interactions.
- •Another white dwarf, WD J1011+2845 located 48 light-years away, was identified as the reddest star featuring carbon molecules on its surface.
Key Questions Answered
Scientists have named the newly discovered green star WD J1330+6435, which is located about 326 light-years away from Earth.
The star turned green because it is a cosmic zombie that is consuming its own rocky planets, accumulating massive amounts of elements like sodium, calcium, and lithium in its atmosphere which absorb orange and yellow light.
While normal white dwarfs are white due to their temperature, extreme densities and atmospheric chemical compositions—such as carbon creating pink or purple hues and planetary debris creating green or yellow—cause them to exhibit diverse colors.
