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.
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 discovered in 1868 by Pierre Janssen and Norman Lockyer
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.
Helium as an element has been around since fusion began in stars, but it was discovered in 1868
they where discovered in 1868
Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-César Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868. Sir Norman Lockyer, an English astronomer, realized that this line, with a wavelength of 587.49 nanometers, could not be produced by any element known at the time. It was hypothesized that a new element on the sun was responsible for this mysterious yellow emission. This unknown element was named helium by Lockyer.
Helium pays homage to Helios, a Greco-Roman sun god. Helium was spectroscopically discovered in the sun"s rays before it was found on earth. It was discovered formally in 1868.
The element "Helium" was unknown on Earth when it was discovered by spectral lines from the Sun. It was later discovered here on Earth, in Texas natural gas deposits.
