NASA's Astronomy Picture of the Day for October 22, 2026, features an illustration of the white dwarf star WD J1330+6435. The image depicts the star surrounded by an accretion disk composed of gas and rocks.
Astronomers have identified that certain white dwarf stars can exhibit colors such as yellow, green, cyan, pink, or purple. These color shifts occur when trace elements accreted by the star interact with its atmosphere, altering the star's typical white appearance.
Despite these findings, these stars remain too faint for direct observation from Earth. The illustration was created by Mark A. Garlick from the University of Warwick.
