Plutonium238 is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium238 is a very powerful alpha emitter. This makes the plutonium238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units. The density of plutonium238 is 19.329 g/cm³.

And according to this space article over on the Sunday Express, we are running out of this epic material. NASA and all of her sister companies need this epic space-kryptonite in order to travel space, or whatever.

Oh me, oh my… What ever shall we do?

No more plutonium-238, no more space illustrations. As a matter of fact, if we illustrate one fast enough, I bet we could find an exo-planet within our reach that is made of this stuff!

What do you think?

Thank God for NASA illustrators. I wasn’t sure what were going to do.
