The Sun Will Turn Into a Giant Crystal Ball After It Dies

  • The Sun Will Turn Into a Giant Crystal Ball After It Dies

Dr. Trembley mentioned that no other direct evidence has ever been discovered that white dwarfs crystallize ( the process of turning solid from liquid). "It was predicted fifty years ago that we should observe a pile-up in the number of white dwarfs at certain luminosities and colours due to crystallisation and only now this has been observed".

White dwarf stars are probably the oldest stellar objects in the universe.

White dwarfs are the residual cores of stars whose masses are similar to that of the Sun. If you were keeping track with a thermometer, you would find that the temperature of water stalls at zero degrees Celsius for a bit - the exact time that the H20 molecules are rearranging themselves into the crystal structure of ice.

The Sun still has about five billion years before it becomes a white dwarf, and the astronomers estimate that it will take another five billion years after that to eventually cool down to a crystal sphere.

The substances that make out the crystal spheres are oxygen and carbon which under such a high density make the stars look like metal.

They distinguished a heap up, an excess in the number of stars at explicit colors and luminosities that don't compare to any single mass or age.

The team selected 15,000 white dwarf candidates that were located within 300 light-years of Earth, and analyzed their brightness and colors. Then its core will shrink and the rest of the star will puff up into a relatively short-lived red giant phase which will last about 500 million to a billion years before it contracts once again.

According to the authors of the new paper, the release of heat energy alone would not be enough to account for their observations.


The new results suggest that many white dwarfs are considerably older than scientists had thought - up to 15 percent older in some cases, study team members said.

"All white dwarfs will crystallize at some point in their evolution, although more massive white dwarfs go through the process sooner". At some time in their evolution, all white dwarfs will crystallize with more massive ones dying faster than the small ones.

After this contraction the star can still create energy by fusing helium to create carbon and oxygen, Tremblay said.

The interior of a "crystal orb" white dwarf.

The researchers analyzed a whopping 15,109 white dwarfs and mapped their luminosities and colors and saw a unusual group of data points sticking out.

He said the Sun was expected to become a white dwarf and experience crystallisation between 8 and 14 billion years from now.

"It's exciting how scanning stars across the sky and measuring their properties can lead to evidence of plasma phenomena in matter so dense that cannot be tested in the laboratory".
