August 18, in 1868, French astronomer Pierre Jules Janssen noticed in his spectral analysis of the sun a line that could not be replicated in the laboratories, suggesting the presence of an entirely new gas. Helium (also known as "He" in stoichiometry circles) is the lightest of the noble gases. 245-249 An indispensable preliminary was the virtual elimination of oxygen-absorption in the Earth’s atmosphere, and his bold project of establishing an observatory on the top of Mont Blanc was prompted by a perception of the advantages to be gained by reducing the thickness of air through which observations have to be made. All trade marks belong to the respective owners. He named the element helium, from the Greek word helios, meaning sun. ATOMIC NUMBER 2. This remarkable work contains some 6,000 photographs of the Sun taken in the years 1876 to 1903 from the newly established Meudon Observatory, near Paris, which was later to be known as the Paris Astrophysical Observatory. Helium was isolated by Sir William Ramsay and independently by N. A. Langley and P. T. Cleve at 1895 in … This observatory was built in September 1893, and Janssen, in spite of his advanced age of 69 years, made the ascent and spent four days taking observations. French astronomer Pierre Janssen first detected the presence of helium in an emission spectrum of the sun. He studied at home and, at the age of 16, when he started to work as a bank clerk. Shortly after it was identified as an element and named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Mr. Norman concluded that this bright-yellow line is due to a new element whose existence on the Earth is still unknown and he named it, helium. : Verfahren zur Reinigung eines kontinuierlichen Helium-und/oder Neongasstromes.

Other scientists didn’t believe the astronomers’ account of a new element until 30 years later, when Scottish chemist William Ramsay discovered a perplexing earthly gas hidden inside a chunk of uranium ore.[3], “Curse the man who invented helium! 1868: A French astronomer spots an unknown element, now known as helium, in the spectrum of the sun during a much-anticipated total eclipse. From Britain, Lockyer was first to propose that the line was due to a new element, which he named Helium. This instrument was used to see the yellow line in the sun during the Total eclipse which was used by Pierre Janssen to discover helium. Hinweise auf das Element Helium erhielt man zum ersten Mal aufgrund einer hellen gelben Spektrallinie bei einer Wellenlänge von 587,49 Nanometern im Spektrum der Chromosphäre der Sonne. He named it the “D 3 line. : Daikin has replaced R22 with helium. This radiogenic helium is trapped with natural gas in concentrations up to seven percent by volume, from which it is extracted commercially by a low-temperature separation process called fractional distillation. An English astronomer by the name of Norman Lockyer observed the same spectra and proposed the name helium after the Greek name for the sun, Helios. On October 20 of the same year, English astronomer Norman Lockyer also observed a yellow line in the solar spectrum, which he named the D3 Fraunhofer line because it was near the known D1 and D2 lines of sodium. The first evidence of helium was obtained on August 18th, 1868 by French astronomer Jules Janssen. An English astronomer by the name of Norman Lockyer observed the same spectra and proposed the name helium after the Greek name for the sun, Helios. After Pierre had discovered helium on the Sun many scientist did not believe him because they thought it was impossible for an element to exist on the Sun. Jules Janssen c. 1895. Pierre-Jules-César Janssen, a French astronomer first observed the yellow line spectrum during the solar eclipse in 1868. Pierre Janssen, who was a French astronomer discovered helium in 1868. Helium is used instead of the nitrogen in normal air because, after a long dive, helium leaves the body faster than nitrogen, allowing faster decompression. Despite being the second most abundant element in the observable universe, helium is relatively rare on Earth, the product of the radioactive decay of elements like uranium. Janssen also is credited with discovering the gaseous nature of the solar chromosphere. It holds court in stars (named after the Greek god of the sun, Helios) and kid's balloons.
