The Full Story
Helium was first identified on Earth in 1895 by Scottish chemist William Ramsay while studying the mineral cleveite. Before that, astronomers had seen an unknown yellow spectral line in the Sun in 1868, and the element was named helium after the Greek word for the Sun, Helios. Its Earth-based discovery confirmed that an element first found in space also existed on our planet. Helium later became important in cryogenics, balloons, and many scientific instruments.
