where was helium discovered

Helium was first identified in the Sun during a solar eclipse in 1868 by French astronomer Pierre Janssen and, independently, by English astronomer Norman Lockyer. They observed a bright yellow spectral line in the Sun’s chromosphere and concluded it represented a new element, which Lockyer named “helium” after the Greek word for the Sun, Helios. The element was later isolated on Earth in 1895 by Sir William Ramsay, who identified it in the mineral cleveite (and subsequently characterized its properties). These events mark helium’s discovery sequence from extraterrestrial observation to terrestrial isolation.
