ChemistryHistory of Science
Quick Answer
Helium was the first element discovered in the Sun by spectroscopy in 1868. It was identified in the solar spectrum before it was isolated on Earth.
The Full Story
Helium became famous as the first element discovered through spectroscopy rather than by direct chemical extraction. During a solar eclipse in 1868, astronomers noticed a yellow spectral line that did not match any known element. The new element was named helium after Helios, the Sun. It was not isolated on Earth until 1895, when William Ramsay found it in a uranium ore mineral.
