The Aquarius Dwarf

Explanation: Our Milky Way Galaxy is not alone. It is part of a gathering of about 50 galaxies known as the Local Group . Members include the Great Andromeda Galaxy (M31), M32 , M33 , the Large Magellanic Cloud , the Small Magellanic Cloud , Dwingeloo 1 , several small irregular galaxies , and many dwarf elliptical and dwarf spheroidal galaxies . Pictured above is the Aquarius Dwarf , a faint dwarf irregular galaxy over 3 million light years away. An earlier APOD erroneously identified the above image as the Sagittarius Dwarf .
