The Cosmic Jewels of Irregular Dwarf Galaxy Sextans A | Mayall Telescope
Sextans A is displayed in style in this gorgeous image, which showcases the irregular shape of this dwarf galaxy. Irregular galaxies such as Sextans A do not have the regular appearance of spiral or elliptical galaxies, but instead display a range of weird and wonderful shapes. These galaxies are relatively small, and they are often susceptible to distortions resulting from close encounters or collisions with larger galaxies—sometimes leading to their irregular shapes. Sextans A is particularly small, measuring only about 5,000 light-years across.
