While most spiral galaxies, including ourown Milky Way
, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solospira mirabilis
seems to wind from a prominent ring of bluish, newborn star clusters and red tinted star forming regions.The odd galaxy also
sports obscuring dust lanes a yellowish central bar structure composed of an older population of stars. NGC 4725 is over 100 thousand light-years across and lies 41 million light-years away in the well-groomed constellationComa Berenices
of the formation of single spiral arms suggest that they can be either leading or trailing arms with respect to a galaxy'soverall rotation
. Also included in the frame, sporting a noticably more traditional spiral galaxy look, is a more distant background galaxy.
