Astronomers Discover First-Ever Green Star and Reddest White Dwarf

• A new study published in RAS Techniques and Instruments reveals the discovery of the first green star.
• The study also identifies the reddest white dwarf ever observed, expanding the known color spectrum of these stellar remnants.
• White dwarfs are the dense, cooling cores left after low- to medium-mass stars exhaust their fuel.
• The findings suggest that the color of a white dwarf can vary significantly, influenced by factors such as the consumption of planetary material.
• The discoveries contribute to a better understanding of the lifecycle and characteristics of white dwarfs.
