Quasar

TECHNICAL DEFINITION

A quasar (quasi-stellar radio source) is an extremely energetic and distant active galactic nucleus, powered by a supermassive black hole rapidly accreting surrounding gas and dust, emitting prodigious amounts of electromagnetic radiation across the spectrum, making them among the brightest objects in the universe.

BACKGROUND

The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the United States' civil space program and for research in aeronautics and space. Headquartered in Washington, D.C., NASA operates ten field centers across the U.S. and is organized into three mission directorates: Human Spaceflight, Research and Technology, and Science. Established in 1958 amid the Space Race, NASA succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space program a distinct civilian orientation focused on peaceful applications. Since then, it has led most American spaceflight programs, including Project Mercury, Project Gemini, the Apollo program, Skylab, the Space Shuttle, the International Space Station (ISS) and the ongoing multi-national Artemis program.

SYNONYMS & ALIASES

• Quasi-stellar object
