Is it wrong that I was hoping for something along the lines of:

except where they are noting how helium is being allowed to escape and not being captured as was previously done by the now shut down U.S. National Helium Reserve.

Only 880,000 years at our current average speed. Mind blowing, that.

Rocky, you say question?

There is a market shortage of helium but shouldn't be:

There's also helium in methane, but unfortunately few places crack out the helium from natural gas.

TIL Helium kills Kudzu and powers fusion power plants.

wow 50 light years is indeed "nearby" in relative terms

nearly 6x the size of earth though, good luck trying to launch a probe off that surface

NASA has a neat "exoplanet catalog" which is about to leap in size next few years with new telescopes and techniques
