    One thing worth noting is our popular notion of what a star seems to be is quite different from what astronomers have.

    One example, Canis Majoris has a radius of about 1420 solar radii. But its mass is roughly 17±8 times the mass of the Sun and therefore an average density of 5.33 to 8.38 mg/m3. “It is over 100.000 times less dense than Earth’s atmosphere at sea level.”

      My layman definition of what a star is is "it's somewhere in the sky and it gives off light". The word "density" wouldn't even come to my mind

      Yes and no. It’s fluffy on the outside, but at the core it’s likely denser than our sun.

    Soundgarden was apparently prophetic with their hit song "Black Hole Sun."

      May Chris Cornell rest in peace. He should have seen this.
