A cosmic diamond in sight: this is the metamorphosis of a white dwarf – National Geographic in Spanish


A group of scientists discovered that a white dwarf very similar to our sun is turning into a cosmic diamond.

Space is full of mysteries and unexplained surprises. During the observation of a star, a group of scientists discovered that the cosmic body is transforming into a diamond from outer space. Through a crystallization process, the white dwarf is becoming a space jewel.

From plasma to crystal

The transformation of stars into glowing crystals had been predicted for decades, but it was not until the launch of the Gaia space mission that it was confirmed. The process is the following. First, the matter of the white dwarf is compressed so much that electrons detach from atoms. SamaGametrons become degenerate gas which allows them to move freely. This process causes the core to be made of carbon and oxygen, surrounded by the gas of electrons. While a normal gas depends on temperature, a degenerate gas does not. The drop in temperature in the cores of white dwarfs causes ions to HE reorganize into an ordered structuregiving way to the creation of crystals.

What we know about the cosmic diamond

The star in question is a star very similar to our sun and its process is a very rare phenomenon according to experts. The exceptionality is not only due to the fact that it is a process described only a few years ago, but also to the microscopic possibility of witnessing the beginning of a process longer than the universe itself.

This cosmic diamond, called HD 190412 C, is located 104 light-years away from Earth, in a star system called HD 190412. Based on the evidence, those in charge of the investigation estimate that they will encounter other similar bodies in the nearby stellar neighborhood.
