During a solar eclipse in 1868, Janssen observed that the sun emitted a yellow wavelength that was unrecorded at that time. Another scientist, Sir Norman Lockyer, named the new element helium. Several years later, while subjecting the uranium-based mineral clevite to various acids in his London laboratory, Ramsay was able to collect helium for the first time.
