An astronaut (from the Ancient Greek ἄστρον (astron), meaning 'star', and ναύτης (nautes), meaning 'sailor') is a person trained, equipped, and deployed by a human spaceflight program to serve as a commander or crew member aboard a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists

Famous People refers to the fame and public attention accorded by the mass media to individuals or groups or, occasionally, animals, but is usually applied to the persons or groups of people (celebrity couples, families, etc.) themselves who receive such a status of fame and attention. Celebrity status is often associated with wealth (commonly referred to as fame and fortune), while fame often provides opportunities to make money.

Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. It contains ultra-low levels of particle densities, constituting a near-perfect vacuum of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is 2.7 kelvins (−270 °C; −455 °F)

Painting is the practice of applying paint, pigment, color or other medium to a solid surface (support base). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. Painting is a mode of creative expression, and the forms are numerous. Drawing, gesture (as in gestural painting), composition, narration (as in narrative art), or abstraction (as in abstract art), among other aesthetic modes, may serve to manifest the expressive and conceptual intention of the practitioner. Paintings can be naturalistic and representational (as in a still life or landscape painting), photographic, abstract, narrative, symbolistic (as in Symbolist art), emotive (as in Expressionism), or political in nature (as in Artivism). A portion of the history of painting in both Eastern and Western art is dominated by spiritual motifs and ideas. Examples of this kind of painting range from artwork depicting mythological figures on pottery, to Biblical scenes rendered on the interior walls and ceiling of the Sistine Chapel, to scenes from the life of Buddha or other images of Eastern religious origin. In art, the term painting describes both the act and the result of the action. The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, clay, leaf, copper and concrete, and the painting may incorporate multiple other materials including sand, clay, paper, plaster, gold leaf, as well as objects. The term painting is also used outside of art as a common trade among craftsmen and builders.
