Sometimes if the conditions are just right a huge diamond! (the final stage of nucleosynthesis of stars that are not more massive is carbon Theoretically, they get dimmer and dimmer until they become "black dwarfs".
First Disney movie?
There are two answers, the first movie was a short done in black and white called "Steamboat Willy" starring mickey and minnie mouse But his first full lenght film was "snow white", it was also his first in color
Why have no white dwarfs cooled to form black dwarfs in the galaxy?
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
What galaxy is a white dwarf in?
There are white dwarfs in every galaxy.
What is more common in our galaxy white dwarfs or stellar mass black holes?
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
What is the biggest black dwarf star?
It is not believed that any black dwarfs exist yet, as the universe is not old enough for a white dwarf to have cooled into one.
What color is most of the stars in your galaxy?
the color of most of the stars in our galaxy are white. They are concered white dwarfs
What is the difference between white dwarfs and black dwarfs?
their colour is one thing but a black dwarf originates from a white dwarf
The longest part of the total life of most stars is spent?
White dwarf stars are theorized to be the final evolutionary state of all stars that did not become neutron stars. This stage is the longest in a stars life outside of black dwarfs which are white dwarfs that have cooled dramatically.
What is larger a black dwarf or a planet?
A black dwarf would be smaller than some planets but larger than others. A black dwarf is simply a cooled white dwarf. White dwarfs range from slightly smaller than Earth to about twice Earth's diameter.
Are there more white dwarfs of more black holes?
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
How does a small or dwarf star form?
A dwarf star could form in different ways depending on what kind. Red dwarfs and brown dwarfs are formed when nebula compresses into a giant burning ball of gas, just like most stars do; white dwarfs are formed after a star became a red giant and blown off its outer layers, the remaining core became a white dwarf; black dwarfs are formed after white dwarfs cooled down and stopped emitting visible light.
Are black dwarfs a solid liquid or a gas?
None of the above. White dwarfs and the black dwarfs they will become consist of a unique state of matter called electron degenerate matter.
How Many Black Dwarfs are thought to exist?
No black dwarfs are thought to exist. The estimated time it takes for a white dwarf to cool to a black dwarf is greater than the current age of the universe.
