Hubble peeks into the homes of quasars
News story originally written on November 19, 1996

NASA's Hubble Space Telescope (HST) is providing astronomers with high resolution images of one of the most baffling objects in the universe, quasars. These new images taken from HST's Wide Field Planetary Camera 2 (WFPC2) show that quasars live in a remarkable variety of galaxies.

Quasars were discovered only 33 years ago and are the universe most energetic objects. Violent interactions and collisions between pairs of galaxies are thought to trigger the birth of quasars. Quasars are not much bigger than Earth's solar system but emit 100 to 10,000 times as much light as an entire galaxy contaning hundred billion stars.
