What it means
During an eclipse in 1868 astronomers split the sunlight from the solar edge and saw a yellow line that matched no element in any laboratory. They named the missing element after the Greek word for sun. It took another twenty seven years for helium to be pulled out of a mineral on Earth and confirmed, which makes it the one element that was found in space first.
