NGC 247 and Friends Image Credit & Copyright : CHART32 Team, Processing - Johannes Schedler Explanation : About 70,000 light-years across, NGC 247 is a spiral galaxy smaller than our Milky Way. Measured to be only 11 million light-years distant it is nearby though. Tilted nearly edge-on as seen from our perspective, it dominates this telescopic field of view toward the southern constellation Cet..

NGC 2403 in Camelopardalis Image Credit & Copyright : Martin Pugh Explanation : Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish gl..

IC 342 : The Hidden Galaxy Image Credit & Copyright : Arturas Medvedevas Explanation : Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only ..

Magellanic Galaxy NGC 55 Image Credit & Copyright : Acquisition – Eric Benson, Processing - Dietmar Hager Explanation : Irregular galaxy NGC 55 is thought to be similar to the Large Magellanic Cloud (LMC). But while the LMC is about 180,000 light-years away and a well-known satellite of our own Milky Way Galaxy, NGC 55 is more like 6 million light-years distant, a member of the Sculptor Galaxy G..

Wolf-Lundmark-Melotte Image Credit : ESO, VST/Omegacam Local Group Survey Explanation : Named for the three astronomers instrumental in its discovery and identification, Wolf – Lundmark - Melotte (WLM) is a lonely dwarf galaxy. Seen toward the mostly southern constellation Cetus, about 3 million light-years from the Milky Way, it is one of the most remote members of our local galaxy group. In fa..

M31 versus M33 Image Credit & Copyright : Malcolm Park (North York Astronomical Association) Explanation : Separated by about 14 degrees (28 Full Moons) in planet Earth's sky, spiral galaxies M31 at left, and M33 are both large members of the Local Group, along with our own Milky Way galaxy. This narrow- and wide-angle, multi-camera composite finds details of spiral structure in both, while the ..

The Stars of the Triangulum Galaxy Image Credit : NASA, ESA, M. Durbin, J. Dalcanton, and B. F. Williams (University of Washington) Explanation : Like grains of sand on a cosmic beach, stars of the Triangulum Galaxy are resolved in this sharp mosaic from the Hubble Space Telescope's Advanced Camera for Surveys (ACS). The inner region of the galaxy spanning over 17,000 light-years is covered at e..
