NASA's Astronomy Picture of the Day for October 22, 2026, featured an illustration of the white dwarf WD J1330+6435 surrounded by an accretion disk of gas and rocks orbiting the star. The image is credited to Mark A. Garlick and the University of Warwick.

The accompanying explanation notes that all stars beyond the Sun are so distant they appear as points, mostly white but sometimes noticeably red or blue, with color typically tied to temperature. White dwarfs are small, faint remnants left when a star like the Sun exhausts its nuclear fuel. Astronomers recently found that some white dwarfs, despite the name, would appear yellow, green, cyan, pink or purple, because accreted trace elements interact with the stellar atmosphere and shift its normally white color.

The text adds that these stars are too faint to see with the unaided eye. The illustration accompanies the day's entry rather than depicting an observed image.
