Helium discovery
The discovery of helium's existence preceded its discovery as an element on Earth. In 1868 Pierre J. C. Janssen travelled to India to study a total eclipse and he observed a new line in the corona spectrum, which meant an unknown element was present on the sun. (He named it helium thinking it would be a metal.)The state of helium in these two regions has differences as well. Below the STR, helium is partially ionized. This means it has lost an electron, but still has one left. ... Studying the Sun The sun has not always been a subject of scientific discovery and inquiry. For thousands of years, the sun was known in cultures all over the world as a ...The state of helium in these two regions has differences as well. Below the STR, helium is partially ionized.

The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. East of First Helium's 15-25 discovery well, exploration for natural gas had been effectively deterred by the high nitrogen content of the gas as nitrogen decreases heating value and marketability ...
On August 18, 1868, Janssen managed to do just that. He became the first person to observe helium, an element never before seen on Earth, in the solar spectrum. At the time, though, Janssen didn...By 1929, the new Amarillo Helium Plant was ready to open. The volume of helium produced at the Amarillo plant quickly grew. By about 1934, the Amarillo Helium Plant was the only commercial helium plant in the world. In the 1940s, World War II created new demands for helium. The research labs discovered ways to refine more helium. They also ...Helium couldn’t quite match the lifting power of hydrogen, but it had the distinct advantage that it was chemically inert and would not burn if struck by enemy fire. A decade or so before the outbreak of war, helium had been discovered to be naturally present in some deposits of natural gas, notably in Texas. WASP-17 b's atmosphere is composed primarily of hydrogen and helium, along with small amounts of water vapor and hints of carbon dioxide and other molecules. ... Unprecedented discovery seems to ...

What is perhaps surprising, is that …An isotope called helium-4 has two protons and two neutron particles in the nucleus. Helium-4 is a stable isotope of the element of helium that makes up 99% of the earth’s helium. One-quarter of the ordinary matter in the universe by mass is made up of helium-4. Scientists discovered helium-4 in the mid-1930s.
