Hydrogen was discovered.
In 1868 Jules Janssen and Norman Lockyear discovered spectral lines of an unknown element in Sun - the element was named helium. In 1895 Per Teodor Cleve and Nils Abraham Langled discovered helium in an uranium mineral.
Helium is the element named after the Greek sun god Helios and was first discovered in the spectrum of the sun during a solar eclipse in 1868 by French astronomer Jules Janssen and British astronomer Joseph Norman Lockyer.
The element first found in the Sun's spectrum is helium. It was discovered in 1868 by French astronomer Jules Janssen and British astronomer Joseph Norman Lockyer during a solar eclipse.
Pierre Janssen, who was a French astronomer discovered helium in 1868. It was the English astronomer Norman Lockyer who proposed the name helium after the Greek name of the sun, Helios.
Helium was first discovered in the spectrum of the sun before it was found on Earth. Scientists noted a yellow line in the solar spectrum during a solar eclipse in 1868, which was later determined to be due to the presence of helium.

Helium was first discovered in 1868 by French astronomer Jules Janssen during a solar eclipse when analyzing the sun's spectrum. However, it was British scientist Sir Joseph Norman Lockyer who named the element "helium" after the Greek god of the sun, Helios.
The chromosphere of the sun was first discovered by French astronomer and physicist Jules Janssen during a solar eclipse in 1868.
Sir Norman Lockyer discovered helium in 1868 in the spectrum of the sun during a solar eclipse. He noticed a yellow line in the sun's spectrum that did not correspond to any known element at the time, leading to the discovery of the new element helium.
Helium. It was discovered on the Sun many years before it was discovered on Earth.
It is Helium a noble gas.
Helium was discovered during a solar eclipse in 1868 by French astronomer Jules Janssen. He is jointly credited with detecting the element along with Norman Lockyer.
