These Are Big Stars, Duh

BBC News reports that scientists have identified the three single largest stars known to mankind.

The largest is somewhere around 1.5 billion kilometers across. This means that if our sun was this size, it would extend beyond Jupiter.

This is exactly why I like astronomy and astrophysics. A ball of hydrogen, set on fire in the single largest fusion explosion known to the universe, of such enormous size that it swallows the orbits of Mercury, Venus, Earth, Mars and Jupiter... I think it's safe to say that's impossible.

Simply impossible.

And yet... it's out there...
