WebDwarf Galaxies. Dwarf galaxies are the smallest objects in the universe which appear to contain vast amounts of dark or "missing" matter. The presence of this dark matter is inferred from the difference between the mass of these galaxies as measured by adding up all of their visible light, and the mass determined from dynamical measurements. WebHubble has also made detailed observations of the dwarf galaxy NGC 2366, which is home to a bright, star-forming nebula and is close enough for astronomers to discern its individual stars. While we see the stars because they shine brightly, galaxies are overwhelmingly made up of the empty space between them. Hubble’s high-resolution images ...
