the universe's second-most-common element and the diva that escapes Earth forever.
means A lightweight, colorless, inert noble gas — the second element on the periodic table — used to fill balloons, cool superconducting magnets, and raise voices an octave.
from From the Greek hēlios, 'sun' — because helium was first spotted in 1868 not in any earthbox or laboratory but in the spectrum of the Sun, glowing as a mysterious yellow line during a solar eclipse. It was named for the star it was found in years before anyone caught it here on Earth, making it the only element discovered in the heavens before the ground. The '-ium' suffix tagged it as a metal, which it absolutely is not — a hopeful guess that stuck.
