A study published this month in RAS Techniques and Instruments, led by Mark Hollands of Warwick University, reports that white dwarf stars can display unexpected colors such as green and pink, rather than the standard red-to-blue spectrum typical of most stars. Researchers attribute this to trace elements like sodium, calcium or carbon interacting with dense helium in the star's atmosphere as it cools, absorbing specific wavelengths of light.
