quasar

 

[ หˆkweษชzษ‘หr ]

Noun
Context #1 | Noun

astronomy

A quasar, or quasi-stellar object, is an extremely luminous celestial object believed to be powered by a supermassive black hole at the center of a distant galaxy. Quasars are among the brightest and most energetic objects in the universe, emitting vast amounts of energy to outshine all the stars in their host galaxy. The light emitted from quasars can take billions of years to reach Earth, allowing astronomers to observe their properties and gain insights into the early universe. Quasars were first identified in the 1960s, and they provide critical information about cosmic evolution and the formation of galaxies.

Synonyms

celestial body, luminous object, quasi-stellar object.

Examples of usage

  • The quasar was discovered using a radio telescope.
  • Astronomers study quasars to understand galaxy formation.
  • It was challenging to observe the distant quasar due to its redshift.
  • Quasars emit a significant amount of radiation.
  • The brightness of the quasar changes over time.

Etymology

The term 'quasar' was coined in the 1960s and derives from the phrase 'quasi-stellar radio source.' This refers to the fact that these objects were initially identified as sources of radio waves, which appeared to be similar to stars when viewed through telescopes. The discovery of quasars was significant as it heralded the recognition that there were celestial objects much more powerful than normal stars. Early research into quasars established their incredible distances from Earth, leading to important revelations about the expansion of the universe. As technologies advanced, and spectroscopic techniques improved, astronomers were able to gather more information about the nature of quasars, further altering our understanding of cosmology and the universe's structure.
