The first evidence of helium was observed on August 18, 1868 as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun.
Helium was discovered in 1868 by French astronomer Jules Janssen during a solar eclipse while observing the sun's spectrum.
Helium was first discovered by the French astronomer Pierre Jansen. Helium is named after the Greek word for sun - helios.
Pierre Janssen was a French astronomer who discovered helium in 1868. India.
From the Sun. Helium was discovered on the Sun (to be precise, in its spectrum), before it was discovered on Earth.
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.
Helium was discovered in the sun specroscopically
Helium was first discovered as a component of the sun before being discovered on earth. Hence the name.

The spectral line for helium was first discovered by a French astronomer working in India during a solar eclipse. An English astronomer determine that this spectral line was due to a previously unknown element. An Italian physicist first detected helium on Earth. A Scottish chemist, was the first to isolate helium on Earth. So where was helium discovered? Depending on how you define "discovery" it was discovered in India, France, England, Italy or Scotland.
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 by the French astronomer Pierre Jansen. Helium is named after the Greek word for sun - helios.
Because helium was discovered by spectral methods in the Sun.
Pierre Janssen discovered helium in 1868 during a solar eclipse while observing spectral lines in the sun's corona.
