Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.

Where did helium get his name from?
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.
What is the reason for the naming helium?
The element helium was first identified on the sun by examination of its spectral lines. While it was later also discovered on earth, because it was first found on the sun (Helios in Greek) it was named for that location.
What noble gas had been discovered in the sun?
Helium was first discovered in the sun. It was identified by its unique spectral lines during a solar eclipse in 1868 by French astronomer Jules Janssen and independently by English astronomer Joseph Norman Lockyer.
What is the origin of the name for helium?
The name "helium" is derived from the Greek word "helios," which means sun, as the element was first discovered in the spectrum of the sun.
Why is helium called so?
Helium was first dissolved in the sun. It gets its name from the Greek word, Helios, meaning the sun

What are the evidences for Helium and Hydrogen in sun?
Scientists can determine the contents of stars using spectrometer (spectrograph or spectroscope.) Basically different compounds give off different wavelengths of of light. By measuring the light you can identify the compound.

Helium was first discovered in the sun. It was identified by its unique spectral lines during a solar eclipse in 1868 by French astronomer Jules Janssen and independently by English astronomer Joseph Norman Lockyer.
Which element was first identified far away in space inside the sun?
The answer is Helium the scientist at Kennedy research station in around 1950's studied the spectrum received form the sun and they identified that 2 hydogen atoms moving at high speed and at high temperature produce helium moleclue which results in an exothermic reaction i.e. produces heat along with it.
Is there helium on the sun?
Yes. The Sun comprises about 25% helium. (24.8%)
What does helium have to do with the sun?
The sun is actively converting hydrogen to helium in its core and is roughly 23% helium. Helium was first discovered by examining sunlight.
Does the sun have helium?
Yes, the sun contains helium. Helium is produced in the sun through nuclear fusion reactions where hydrogen atoms combine to form helium. Helium is one of the main elements present in the sun's composition.
What percentage of helium is in the sun?
Helium makes up about 24% of the sun's mass.
Helium was discovered in the sun before it was discovered on earth. How?
Helium was discovered in the sun specroscopically
