bklynmed: Star-Forming Region S106 The bipolar S106 shows bright gas in two distinct lobes. The faint stars located near the nebulosity are brown dwarf candidates associated with the region of star formation. Credit: NASA
NGC 2623 is really two galaxies that are becoming one. Seen to be in the final stages of a titanic galaxy merger, the pair lies some 300 million light-years distant toward the constellation Cancer. Filled with dust, gas, and young blue star clusters, the opposing tidal tails extend well over 50,000 light-years from the merged nucleus. Likely triggered by the merger, accretion by a supermassive black hole drives activity within the nuclear region.
This is Pickering's Triangle, which is part of the Veil Nebula, a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop. It is brightest at the north central edge of the loop, but is visible in photographs continuing toward the central area of the loop.
