Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed. Neon was the second of these three rare gases to be discovered and was immediately recognized as a new element from its bright red emission spectrum. The name neon is derived from the Greek word, νέον, neuter singular form of νέος, meaning 'new'. Neon is chemically inert, and no uncharged neon compounds are known. The compounds of neon currently known include ionic molecules, molecules held together by van der Waals forces and clathrates.
Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. It is typically hard but friable. Its quality is ranked higher than lignite and sub-bituminous coal, but lesser than anthracite. It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to 85 °C (185 °F) or higher.
A period 3 element is one of the chemical elements in the third row of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when the periodic table skips a row and a chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the same vertical columns. The third period contains eight elements: sodium, magnesium, aluminium, silicon, phosphorus, sulfur, chlorine and argon. The first two, sodium and magnesium, are members of the s-block of the periodic table, while the others are members of the p-block. All of the period 3 elements occur in nature and have at least one stable isotope.
Austenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element. In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (727 °C); other alloys of steel have different eutectoid temperatures. The austenite allotrope is named after Sir William Chandler Roberts-Austen (1843–1902); it exists at room temperature in some stainless steels due to the presence of nickel stabilizing the austenite at lower temperatures.
A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence. The light cannot be turned off and can be used only once. The used tube is then thrown away. Glow sticks are often used for recreation, such as for events, camping, outdoor exploration, and concerts. Glow sticks are also used for light in military and emergency services applications. Industrial uses include marine, transportation, and mining.
The Moon is Earth's only natural satellite.

The Bluegrass Balloon Festival, formerly called the Adam Matthews Balloon Festival, was the fifth largest hot air balloon festival in the United States, and the largest in the state of Kentucky. From 1999 to 2009, it was held annually in late September at Bowman Field in Louisville, Kentucky.
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp".
Calcium sulfide is the chemical compound with the formula CaS. This white material crystallizes in cubes like rock salt. CaS has been studied as a component in a process that would recycle gypsum, a product of flue-gas desulfurization. Like many salts containing sulfide ions, CaS typically has an odour of H2S, which results from small amount of this gas formed by hydrolysis of the salt.
The Eastern Kentucky Coalfield is part of the Central Appalachian bituminous coalfield, including all or parts of 30 Kentucky counties and adjoining areas in Ohio, West Virginia, Virginia and Tennessee. It covers an area from the Allegheny Mountains in the east across the Cumberland Plateau to the Pottsville Escarpment in the west. The region is known for its coal mining; most family farms in the region have disappeared since the introduction of surface mining in the 1940s and 1950s.
Boyd County is a county located in the U.S. state of Kentucky. As of the 2020 census, its population was 48,261. The county seat is Catlettsburg, and its largest city is Ashland. The county was formed in 1860. Its 160 square miles (410 km2) are found at the northeastern edge of the state near the Ohio River and Big Sandy River, nestled in the verdant rolling hills of Appalachia. Boyd County is in the Huntington-Ashland, WV-KY-OH metropolitan statistical area.
Festuca arundinacea (syn., Schedonorus arundinaceus and Lolium arundinaceum) is a species of grass commonly known as tall fescue. It is a cool-season perennial C3 species of bunchgrass native to Europe. It is an important forage grass throughout Europe, and many cultivars have been used in agriculture. It is also an ornamental grass in gardens, and a phytoremediation plant.
Whitehouse is an unincorporated community in Johnson County, Kentucky, United States. In its early years, it was called Mt. Carbon and housed families from two different coal companies, Sandy River Cannel Coal Company and Whitehouse Cannel Coal Company. In 1887, the Ohio and Big Sandy Railroad, bought by C&O Railroad in 1892, reached the community and named the station "Whitehouse" after a large white house that served as a landmark for riverboats. On April 23, 1887, the community named its post office Myrtle, but in 1901, both the post office and community were renamed Whitehouse, after the railroad station. Whitehouse's ZIP code is 41240.
A flame is affected by the fuel introduced and the oxygen available. A flame with a balanced oxygen-fuel ratio is called a neutral flame. The color of a neutral flame is semi-transparent purple or blue. This flame is optimal for many uses because it does not oxidize or deposit soot onto surfaces.
The Tolu Site is a prehistoric archeological site of the Mississippian culture near the unincorporated community of Tolu, Crittenden County, Kentucky, United States. It was built and occupied between 1200-1450 CE. No carbon dating has been performed at the site, but analysis of pottery styles suggest its major habitation period was 1200 to 1300 CE. The site originally had three mounds, a burial mound, a substructure platform mound and one other of undetermined function. It was excavated in 1930 by W.S. Webb and William D. Funkhouser.
Ruler on Ice is a Thoroughbred racehorse that won the 2011 Belmont Stakes. He was bred and foaled in Kentucky by Brandywine Farm in partnership with Liberation Farm on. He is a chestnut gelding sired by Hill 'n' Dale Farms' Roman Ruler out of the Saratoga Six-bred mare, Champagne Glow. The colt was consigned as lot 988 at the 2009 Keeneland September yearling auction, where he was purchased by George and Lori Hall for $100,000. Ruler on Ice only won one minor race after winning the Belmont and was retired from racing in July 2014. He lives in Versailles, Kentucky at the farm of his owners.
