  "account": "Astronomers have discovered a unique green star, marking the first time such a celestial body has been identified. This green star, named WD J1330+6435, is a white dwarf located approximately 280 light-years away in the constellation Draco. White dwarfs are the remnants of low- to medium-mass stars that have exhausted their nuclear fuel and shed their outer layers. Typically, white dwarfs exhibit a white color due to their high temperature. However, the sodium content in WD J1330+6435 has turned it a ghostly shade of chartreuse. The sodium atoms in this white dwarf are bombarded by surrounding helium atoms, altering the sodium's atomic energy levels. This alters the sodium's absorption of light, resulting in a green glow that would not be possible for sun-like stars. The discovery was part of a study assessing the color of white dwarfs as perceived by the human eye. Scientists found that white dwarfs can span almost every color of the spectrum, forming distinct groups based on their atmospheric composition. While WD J1330+6435 is the first documented green star, green stars have been a part of science fiction, including the recent comic book movie \"Supergirl.\"",
