❓ why
Why is helium named before it was discovered on Earth?
Quick Answer
Helium was identified in the Sun’s spectrum in 1868 before scientists isolated it on Earth. Its name comes from Helios, the Greek word for Sun.
The Full Story
Helium is a famous example of an element discovered in space first. In 1868, astronomers Jules Janssen and Norman Lockyer independently observed a yellow spectral line in sunlight during a solar eclipse and realized it came from an unknown element. Because it was first seen in the Sun, it was named helium after Helios, the Greek sun god. Helium was later isolated on Earth in 1895 by William Ramsay, confirming that the same element existed here too.
