NGC1705: A Windy Blue Compact Dwarf Galaxy

NGC1705 optical

NGC1705 at a distance of ~6 Mpc, is one of the closest BCD galaxies. It is particularly interesting because it prominently displays some of the most important aspects of the starburst phenomenon. These include a super star cluster and a spectacular galactic wind, both of which are clearly evident in this image which combines blue continuum, red continuum, and H-alpha images in blue, green and red respectively (Lower contrast image, enhancing star cluster). All of these were obtained with the 3.9m Anglo Australian Telescope. This important galaxy has now been observed at many wavelengths with many different telescopes.
