Unlike red dwarfs, brown dwarfs, and white dwarfs, black dwarfs are entirely hypothetical. Once a star has evolved to become a white dwarf, it no longer...

long lifetimes of red dwarfs, it is likely that no black dwarfs have yet formed in the Universe. Do not confuse the term "black dwarf" with "black hole"...

spectrum can be misleading. For example, so-called red dwarfs are a deep shade of orange and brown dwarfs would hypothetically appear to a nearby observer...

is the smallest star. It is referred as a G2 yellow dwarf star. Most other stars are red dwarfs. Betelgeuse is about 20 times the mass of the Sun and...

During this phase, the star inflates to hundreds of times its original size. After the red giant phase the star shrinks and becomes a white dwarf star....

called a 'Black Dwarf'. It is thought that the Universe is just old enough for White Dwarfs to have formed and cooled down to Black Dwarfs, although none...

stars become a black hole. On the other hand, red giants become white dwarfs which then become black dwarfs, each time they emit less and less energy. [Diagram...

Messier 32 (also known as NGC 221 and w:Le Gentil) is a w:dwarf elliptical galaxy about 2.65 million w:light-years away in the w:constellation Andromeda...
