Do you know what a "naked star" is?
A naked star is one with most of its gaseous exterior stripped away. Naked stars are valuable to scientists because they can get a clear look at the nuclear engines that keep stars burning bright.
Do you know how naked stars get to be revealed like that? It's due to close encounters with other stars.
I find something very human about that.

What it actually depicts is the Helix Nebula, a trillion-mile-long tunnel of glowing gases with a dying star at its center. Our own sun may look like this in several billion years.
