Astronomers have identified something once thought practically impossible: a star that would actually appear GREEN to human eyes. 😮
The unusual object, called WD J1330+6435, is a white dwarf located approximately 280 light-years from Earth in the constellation Draco.
White dwarfs are incredibly dense remnants of stars that have exhausted their nuclear fuel. Most appear white, but this one has a remarkable secret.
Researchers from the University of Warwick discovered that rocky debris from its former planetary system had contaminated its atmosphere with elements including calcium, lithium, and sodium.
Under the star's extreme atmospheric pressure, sodium absorbs a much broader range of yellow, orange, and red light than usual.
The remaining light produces a ghostly chartreuse-green appearance.
The researchers calculated this color from the star's spectrum rather than photographing it directly.
Even stranger, their research found that some other white dwarfs could appear pink, purple, or cyan.
The universe apparently has a much stranger color palette than anyone imagined.
