Astronomers at the University of Warwick have discovered the first star ever found that would appear green to the human eye. The white dwarf WD J1330+6435, located around 284 light-years away, has a chartreuse green color due to the presence of sodium in its atmosphere. This finding challenges the belief that white dwarfs only appear white or pale blue. The team also found other white dwarfs that could appear pink, yellow, cyan, and purple if observed closely.
