Helium

Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements.

Helium is the second lightest element and is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this figure in the Sun and in Jupiter. This is due to the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. Most helium in the universe is helium-4, and is believed to have been formed during the Big Bang. Large amounts of new helium are being created by nuclear fusion of hydrogen in stars.

Helium is named for the Greek god of the Sun, Helios. It was first detected as an unknown yellow spectral line signature in sunlight during a solar eclipse in 1868 by French astronomer Jules Janssen. Janssen is jointly credited with detecting the element along with Norman Lockyer. Jannsen observed during the solar eclipse of 1868 while Lockyer observed from Britain. Lockyer was the first to propose that the line was due to a new element, which he named. The formal discovery of the element was made in 1895 by two Swedish chemists, Per Teodor Cleve and Nils Abraham Langlet, who found helium emanating from the uranium ore cleveite. In 1903, large reserves of helium were found in natural gas fields in parts of the United States, which is by far the largest supplier of the gas today.

The Tonight Show

The Tonight Show is an American late-night talk show broadcast from the Rockefeller Center in New York City and airing on NBC since 1954. It is the world's longest-running talk show, and the longest running, regularly scheduled entertainment program in the United States. It is the third-longest-running show on NBC, after only the news-and-talk shows Today and Meet the Press.

Over the course of more than 60 years, The Tonight Show has undergone only minor title changes. It aired under the name Tonight for several of its early years, eventually settling on The Tonight Show after the seating of long-time host Johnny Carson in 1962. In later decades, network programmers, advertisers, and the show's announcers would refer to the show by including the name of the host; for example, it is currently announced as The Tonight Show Starring Jimmy Fallon. In 1957, the show briefly tried a more news-style format. It has otherwise remained a talk show throughout its run.

The Tonight Show began broadcasting in 1954. It has had six official hosts, beginning with Steve Allen (1954–57), followed by Jack Paar (1957–62), Johnny Carson (1962–92), Jay Leno (1992–2009, 2010–14), Conan O'Brien (2009–10), and Jimmy Fallon (2014–present). It has had several recurring guest hosts, a practice especially common during the Paar and Carson eras.
