Hubble captures Galaxy NGC 4394
NASA/ESA Hubble Space Telescope has captured a striking image of Galaxy NGC 4394.
Discovered in 1784 by the German–British astronomer William Herschel, NGC 4394 is a barred spiral galaxy in the constellation Coma Berenices 55 million light-years from Earth. The galaxy is part of the Virgo cluster of galaxies.
NGC 4394 has bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. At the center of NGC 4394 lies a region of ionized gas known as a low-ionization nuclear emission-line region (LINER).
