[SAPOD]Today’s “Space Image”. We introduce characteristic images introduced by sorae in the past, attractive images released by space agencies of various countries, and images submitted by space astronomy fans and experts.

First observational evidence of crystallization discovered! This is an “imaginary drawing of a white dwarf star with a crystallized interior” that sorae introduced in an article on June 23, 2023. The original article introduces the results that show evidence of crystallization beginning on the white dwarf star HD 190412 C, which is located approximately 104 light-years from Earth. Below are some excerpts from the text. White dwarfs are “dead stars” that retain only residual heat from when they were the central core of a star and do not generate new heat, so they are celestial bodies that emit heat into space and cool down. As the temperature decreases, the arrangement of the atoms that make up the white dwarf changes from a random state to an aligned state from the center to the outside…in other words, crystallization is thought to occur. White dwarfs are called “diamonds” because they are thought to form crystals of carbon atoms in a high-temperature, high-pressure environment. It is said that it will take 1,000 trillion years for the entire white dwarf to cool down. Our universe has only been around for regarding 0.001% of that time, so white dwarfs that have completely crystallized into diamonds do not yet exist in our universe. However, since there are white dwarfs in the current universe that are in the early stages of cooling, it would not be surprising if some of them have begun to crystallize. The original article introduces observational results that show evidence of crystallization beginning on the white dwarf star HD 190412 C, which is located approximately 104 light-years from Earth.Read original article
