These ‘Snow White Dwarfs’ Are Cooler Than You Think—Watch the Science Explode! When we think of white dwarfs, we often picture brilliant points of light in deep space, remnants of ancient stars glowing faintly as they cool over billions of years. But hide beneath the surface of this classic image a surprising and cooler category of stars: the so-called Snow White Dwarfs—cool, dense stellar corpses that might seem chilly at first glance, yet pack a scientific punch unlike any other. ### What Are Snow White Dwarfs? Snow White Dwarfs are a rare type of white dwarf characterized by their extremely low surface temperatures—colder than 10,000 Kelvin. Unlike their hotter, bluer cousins, these stars emit most of their light in the infrared and appear faintly blue-white or even whitish in low-resolution views. Their name comes from their unusual color and cool profile, evoking the delicate beauty of snowflakes under pale moonlight.
