All right you guys, knock off the jokes. This is a serious thread.
Speaking of which, never miss an opportunity for a Python reference.

Very cool! Thanks to the OP for sharing.

But, but, but, I remember reading somewhere that there is a limit as to how big a star can be. So, how could that largest star known to men, VY Canis Majoris, be so large compared to our Sun?

A quick look on Wikipedia revealed the following. That is, VY Canis Majoris is a red giant, a star on its last death gasp. It has the mass of 30 to 40 Suns, but has exploded to a size where its density is so low that
With an average density of 0.000005 to 0.000010 kg/m3, the star is a thousand times less dense than the atmosphere of the Earth (air) at sea level. Since the star does not have a uniform density—as it must have a fusing core—the actual density of the outer "surface" at the radius and mass stated (mass ÷ volume, where the volume of a sphere is 4/3 * pi * r3) is far less dense than even the outer atmosphere of the Earth.
Still, here is something impressive about a smaller star, Rigel, that has the mass of 24 Suns, but with the radius 71X that of our Sun (for an average density of 1/15000 that of the Sun). It is so bright that if we were at the same distance from it as we are from the Sun, the power flux would be 71,000 times that of the Sun. It would be 100MW per square meter, instead of a mere 1.4kW!

I thought I remembered a joke about Sodium, but Na.

Yup, good old Uranus. I still remember laughing my butt off everytime someone said that in seventh grade science class. Especially if it was a girl.

Hey I wasn't the only one..Really, all the guys laughed. Honest.

Thanks, Frayne, I didn't realize Uranus was so big.

Did you hear that Oxygen and Magnesium hooked up last night? OMG

No more puns, we've all sulphered enough.

Argon walks into a bar, the bartender says "We don't serve nobles gases here." Argon doesn't react.

These chemistry puns are beginning to Bohr me. It seems like you just want to get a reaction out of us.

Agree! I think about how big and far away the stuff I see in my telescope is and my brain short circuits for a second.

Maybe they should've invested stimulus money on solar companies on the planets around Rigel. They might actually stay in business.

Not sure if this belongs in this thread or somewhere else, but since we're talking elements,
