While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the arm, solo spira mirabilis, seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions. Astronomers refer to NGC 4725, located 41 million light-years away in the constellation Coma Berenices, as a ringed barred spiral galaxy because a prominent ring of stars encircles a bar of stars at its center.

Small Galaxy NGC 4449: is an irregular galaxy in the constellation Canes Venatici. It is located about 12 million light-years away, part of the M94 Group (the Canes Venatici I Group), a galaxy group relatively close to the Local Group containing the Milky Way.

A Tidal Galaxy "A previously unsuspected tidal dwarf galaxy candidate appears only in the ultraviolet, indicating the presence of many hot young stars as seen in this cool space Image. IC 4970, the small disk galaxy interacting with NGC 6872, is located above the spiral’s central region. The spiral is 522,000 light-years across from the tip of one outstretched arm to the tip of the other, which makes it about five times the size of our home galaxy, the Milky Way

NGC 1309 -- A spiral galaxy ~120 million light-years away in the constellation Eridanus. It is about 75,000 light-years across; about 3/4s the width of our own galaxy, the Milky Way. Bright blue areas of star formation can be seen in the spiral arms, while the yellowish central nucleus contains older-population stars.

Spiral Galaxy M81 : One of the brightest galaxies in planet Earths sky is similar in size to our Milky Way Galaxy: big, beautiful M81. This grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed view reveals M81s bright yellow nucleus, blue spiral arms, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hubble/NASA.

M94 lies 15 million light-years distant in the northern  constellation Canes Venatici. The brighter inner part of the face-on spiral galaxy is about 30,000 light-years across. A new multi-wavelength investigation has revealed previously undetected spiral arms sweeping across the outskirts of the galaxy's disk. Credit: R Jay Gabany.
