Galaxies
NGC 4725 is a barred spiral galaxy of more than 100 thousand light-years across, located about 41 million light-years away from Earth in the northern constellation of Coma Berenices. While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. This single arm is tightly wound around the core, and is made up of dust and gas illuminated by newborn stars, many bright blue star clusters and pinkish HII regions where new stars are forming, which are seen more where the arm connects to the central bar. In the center is a population of older yellow stars.
