The white dwarf is a star that evolved to the end, consisting mainly of carbon, and the outside is covered with a layer of hydrogen and helium. The white dwarf star gradually cools and darkens in billions of years. It is small in size and low in brightness, but high in density and high in quality.
The white dwarf star discovered this time is about 900 light years from Earth, in the direction of Aquarius. It is estimated that this white dwarf is about the size of the Earth and has a life span of 11 billion years, about the same as the life of the Milky Way. It is the whitest dwarf star with the lowest temperature and the darkest brightness ever discovered by humans.

Previously, scientists have discovered a white dwarf star named "BPM37093" in Centaurus, with a diameter of 4,000 kilometers and a weight of 10 to 34 square carats. Scientists began with its pulsating oscillations, inferring that its core has crystallized.
However, despite the similar molecular structure, the "diamond" in the universe is not exactly the same as the so-called diamond. It is not the weight of the human body. Therefore, this "Diamond Planet", although worthy of its price, is best suited to its location and is still a shimmer in the vast universe.
