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.
