They compete in the National Hockey League (NHL) as a member of the Metropolitan Division in the Eastern Conference. The Capitals are owned by Monumental Sports & Entertainment, headed by Ted Leonsis.

In 1997 the team moved to the arena now called Capital One Arena, their present home arena in Washington, D.C. The Capitals were founded in 1974 as an expansion franchise, alongside the Kansas City Scouts. The franchise struggled throughout its first eight years of existence. In 1982, David Poile was hired as general manager, helping to turn the franchise's fortunes around. With a core of players such as Mike Gartner, Rod Langway, Larry Murphy and Scott Stevens, the Capitals became a regular playoff contender for the next-fourteen seasons. Since purchasing the team in 1999, Leonsis revitalized the franchise by drafting star players such as Alexander Ovechkin, Nicklas Backstrom, John Carlson and Braden Holtby. The 2009–10 Capitals won the franchise's first Presidents' Trophy for being the team with the most points at the end of the regular season. They won it a second time in 2015–16, and did so for a third time the following season in 2016–17. In addition to 12 division titles and three Presidents' Trophies, the Capitals have reached the Stanley Cup Finals in 1998 and 2018, winning in the latter. The Capitals have retired the use of four numbers in honor of four players. In addition, the team holds an association with a number of individuals inducted into the Hockey Hall of Fame. The Capitals are presently affiliated with two minor league teams, the Hershey Bears of the American Hockey League, and the South Carolina Stingrays of the ECHL.

The Delta Cryogenic Second Stage (DCSS) is a family of cryogenic rocket stages used on the Delta III and Delta IV rockets, and which is planned to be used on the Space Launch System Block 1. The stage consists of a cylindrical liquid hydrogen (LH2) tank structurally separated from an oblate spheroid liquid oxygen (LOX) tank. The LH2 tank cylinder carries payload launch loads, while the LOX tank and engine are suspended below within the rocket's inter-stage. The stage is powered by a single Aerojet Rocketdyne-Pratt & Whitney RL10B-2 engine, which features an extendable carbon-carbon nozzle to improve specific impulse.

The Arameans (Old Aramaic: 𐤀𐤓𐤌𐤉𐤀; Greek: Ἀραμαῖοι; Syriac: ܐܪ̈ܡܝܐ / Ārāmāyē) were an ancient Semitic-speaking people in the Near East, first recorded in historical sources from the late 12th century BC. Aramean homeland was known as the land of Aram, encompassing central regions of modern Syria. At the beginning of the 1st millennium BC, a number of Aramean states were established throughout the western regions of the ancient Near East. The most notable among them was the Kingdom of Aram-Damascus, that reached its height in the second half of the 9th century BC, during the reign of king Hazael. A distinctive Aramaic alphabet was also developed and used for writing in the Old Aramaic language.

The Arameans (Old Aramaic: 𐤀𐤓𐤌𐤉𐤀; Greek: Ἀραμαῖοι; Syriac: ܐܪ̈ܡܝܐ / Ārāmāyē) were an ancient Semitic-speaking people in the Near East, first recorded in historical sources from the late 12th century BC. Aramean homeland was known as the land of Aram, encompassing central regions of modern Syria. At the beginning of the 1st millennium BC, a number of Aramean states were established throughout the western regions of the ancient Near East. The most notable among them was the Kingdom of Aram-Damascus, that reached its height in the second half of the 9th century BC, during the reign of king Hazael. A distinctive Aramaic alphabet was also developed and used for writing in the Old Aramaic language. During the 8th century BC, local Aramean kingdoms were gradually conquered by the Neo-Assyrian Empire. Policy of population displacement and relocation, that was applied throughout Assyrian domains, also affected Arameans, many of whom were resetteled by Assyrian authorities. As a result of a wider dispersion of Aramean communities throughout various regions of the Near East, the speaking area of Aramaic language was also widened, gradually gaining significance and eventually becoming the common language of public life and administration, particularly during the periods of Neo-Babylonian Empire (612–539), and later Achaemenid Empire (539–330). As a result of linguistic aramization, a wider Aramaic-speaking area was created throughout the central regions of the Near East, exceeding the boundaries of Aramean ethnic communities. During the later Hellenistic and Roman periods, minor Aramean states emerged, most notable of them being the Kingdom of Osroene, centered in Edessa, the birthplace of Edessan Aramaic, that later came to be known as Classical Syriac language. From the 1st century AD onward, the process of Christianization was initiated throughout the ancient Near East, encompassing various Aramaic-speaking communities, including Arameans, thus resulting in the creation of Aramean Christianity, represented by prominent Christian leaders and authors, who created their theological and literary works in Aramaic language, most notable of them being saint Ephrem of Edessa (d. 373). In the following period, two consecutive processes have affected Christian Arameans. First process was initiated during the 5th century, when ancient Greek custom of using Syrian/Syriac labels for Arameans and their language, started to gain acceptance among Aramean literary and ecclesiastical elites. Second process was initiated after the Arab conquest in the 7th century, that was followed by Islamization and gradual Arabization of Aramean communities throughout the Near East, ultimately resulting in their fragmentation and acculturation. Remaining communities of Christian Arameans continued to decline throughout the medieval period, divided internally along denominational lines, with majority adhering to Oriental Orthodoxy and thus belonging to the ecclesiastical jurisdiction of the Oriental Orthodox Patriarchate of Antioch, that later came to be known as the Syriac Orthodox Church. During the Early Modern period, studies of Aramaic languages (both ancient and modern) were initiated among western scholars, thus leading to the formation of Aramaic studies as a wider multidisciplinary field, that also includes the study of cultural and historical heritage of Arameans. Linguistic and historical aspects of Aramean studies were widened, since the 19th century, by archaeological excavations of ancient Aramean sites in various regions of the Near East.
