1) Black dwarf
It takes 10 trillion years for a white dwarf to cool off entirely. Our galaxy isn’t even old enough for a black dwarf to physically exist yet, but it lies in our Sun’s future.
2) Closing the curtains
The universe hides the birth of stars from us behind a curtain of dust. Only here are conditions cool enough for the dust and gas to condense and fire-up into new stars.
3) We’re made of stardust
Every single element that is in the periodic table was created via fusion processes deep inside the cores of stars, or indeed recycled by supernovae.
