AM 0644-741 is an unbarred lenticular galaxy, and a ring galaxy which means it has a ring of nebulae around it. The ring was formed by a collision with another galaxy that triggered a gravitational disruption. The disruption caused dust in the galaxy to condense, and form stars, which forced it to then expand away from the galaxy, and create a ring. AM 0644-741 has a 150,000 light-year diameter, and is 300 million light-years from the Milky Way[2].
