Odd couple widely separated by time and space SPACE TELESCOPE SCIENCE INSTITUTE NEWS RELEASE Posted: October 4, 2002
NGC 4319 is 80 million light-years from Earth. Markarian 205 (Mrk 205) is more than 14 times farther away, residing 1 billion light-years from Earth. The apparent close alignment of Mrk 205 and NGC 4319 is simply a matter of chance. Astronomers used two methods to determine the distances to these objects. First, they measured how their light has been stretched in space due to the universe's expansion. Then they measured how much the ultraviolet light from Mrk 205 dimmed as it passed through the interstellar gas of NGC 4319.
At a distance of 1 billion light-years, Mrk 205 is a relatively nearby quasar. Many quasars reside much farther away. Quasars, once known only as mysterious point-like objects, are now known to be distant galaxies that have extremely bright cores. These powerhouses of light are probably fueled by massive black holes. With powerful telescopes like Hubble, it is often possible to see the quasar's surrounding halo of faint starlight, as is clearly visible around Mrk 205.
The Hubble image shows that interacting galaxies and disturbances
within galaxies are a rich source of information about galaxy
structure and evolution.
