Black Holes, Neutron Stars, White Dwarfs, Space and Time
My favorite part is the white dwarf binary system spinning like a pinwheel and going supernova.
Those with a clear sky tonight might see a real white dwarf for themselves tonight. It’s Sirius, the brightest star in the sky, which is actually a binary system of two stars. It takes the stars about 50 years to orbit each other.

We are all in the gutter, but some of us are looking at the stars.

Only Sirius A is visible to the naked eye. The white dwarf component of the binary system is Sirius B which can only be seen with powerful telescopes.
