Pierre Janssen Pierre Jules César Janssen (22 February 1824 – 23 December 1907), also known as Jules Janssen, was a French astronomer who, along with English scientist Joseph Norman Lockyer, is credited with discovering the gaseous nature of the solar chromosphere, and with some justification the element helium. Janssen was born in Paris into a cultivated family. His father, Antoine César Janssen (born in Paris, 1780 – 1860) was a well known clarinettist from Belgian descent (his father emigrated from Walloon Brabant to Paris). His mother Pauline Marie Le Moyne (1789 – 1871) was a daughter of the architect Paul

radioactive decay can collect in natural gas reserves in larger than expected quantities, in some cases having been released by volcanic activity. 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. The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. This line was initially assumed to be sodium. On October 20 of the same year, English astronomer Norman Lockyer observed a yellow line in the solar spectrum, which he named

August 1868 as a bright yellow line during a total solar eclipse in Guntur, India. On 20 October of the same year, English astronomer Norman Lockyer observed a yellow line in the solar spectrum. He took the observation in West Hampstead, United Kingdom. Norman Lockyer set up an observation post at the Vijaydurg Fort for the Solar eclipse of January 22, 1898. In his report he does not mention that he ever had been to the Fort before. On that occasion a platform was built. Since 2009 World Helium Day is celebrated at the Fort. Friday, 18 August 2015, has

(He) is a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas series in the periodic table and whose atomic number is 2. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions. Helium was discovered in 1868 by French astronomer Pierre Janssen, who first detected the substance as an unknown yellow spectral line signature in light from a solar eclipse. In 1903, large reserves of helium were found in the natural gas fields of the United States, which is by far the largest

As of 2007, it is operational and removes iron, aluminum, and some manganese from the water.

the Democratic nominees one of their best showings. In 1980, Rhode Island was one of only six states to vote against Ronald Reagan. Reagan did carry Rhode Island in his 49-state victory in 1984, but the state was the second weakest of the states Reagan won. Rhode Island was the Democrats' leading state in 1988 and 2000, and second-best in 1996 and 2004. Historically, the state was devoted to Republicans until 1908, but has only strayed from the Democrats seven times in the 24 elections that have followed. In 2004, Rhode Island gave John Kerry more than a 20-percentage-point margin

Generation of '36 The Generation of '36 () is the name given to a group of Spanish artists, poets and playwrights who were working about the time of the Spanish Civil War (1936 and 1939). The Generation of '36 was a literary movement that suffered harsh criticism and persecution that followed from the division of neighbors into winners and losers in the various battles of that struggle, as well as the physical hardships and moral miseries arising from social instability and political chaos. These were the ingredients that gave strength to their essentially existentialist philosophy. Ricardo Gullón listed some of

economic-based ethic. For example, it forms the foundation for industrial farming; an increase in yield, which would increase the number of people able to receive goods from farmed land, is judged from this view to be a good action or approach. In fact, a common argument in favor of industrial agriculture is that it is a good practice because it increases the benefits for humans; benefits such as food abundance and a drop in food prices. However, a utilitarian-based land ethic is different from a purely economic one as it could be used to justify the limiting of a person's

Solar eclipse of September 23, 2090 A total solar eclipse will occur on September 23, 2090. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. This solar eclipse will be the first total solar eclipse

Totality will start in the Lesser Sunda Islands in Indonesia, continue across the northern Pacific Ocean, and end in the eastern Pacific. Solar eclipse of June 25, 2150 A total solar eclipse will occur on June 25, 2150. It will be the longest total eclipse since the 11th century.

enthusiastic amateur astronomer and especially interested in solar eclipses. He was a volunteer assistant on the 30 August 1905 solar eclipse expedition to Palma, Majorca. McClean organized 2 astronomical expeditions: one to Flint Island for the 3 January 1908 solar eclipse and the other to Port Davey for the 9 May 1910 solar eclipse; however, bad weather thwarted observations in both expeditions. He also accompanied the expedition organized by Sir Norman Lockyer to Vava'u for the 28 April 1911 solar eclipse. McClean made generous gifts to the Lockyer Observatory. His first flying experience was in 1907 in a balloon race

A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look

Janssen discovered how to observe solar prominences without an eclipse. While observing the solar eclipse of 18 August 1868, at Guntur, Madras State (now in Andhra Pradesh), British India, he noticed bright lines in the spectrum of the chromosphere, showing that the chromosphere is gaseous. Present in the spectrum of the Sun, though not immediately noticed or commented upon, was a bright yellow line later measured to have a wavelength of 587.49 nm. This was the first observation of this particular spectral line, and one possible source for it was an element not yet discovered on the earth. From the
