The Full Story
Helium was first detected in 1868 by astronomers observing the Sun’s spectrum during a solar eclipse. The yellow spectral line did not match any known element on Earth, so the new element was named helium after Helios, the Sun god. Helium was later found on Earth in 1895. This was the first element discovered in space before being isolated on Earth.
