Ring galaxies may look like dazzling jewelry, but they’re anything but that! 💍 Scientists think they may be a product of enormous collisions where a smaller and a larger galaxy meet at just the right angle. tmblr.co/Zz_UqjZAfT9tim Such a collision causes ripples that disturb both galaxies, throwing dust, gas, and stars outward. As this happens, gas clouds collide and trigger the birth of new stars. After just a few million years, stars larger than our own explode as supernovae. 🌟 After these stellar explosions, neutron stars or black holes are left behind and can be found throughout the ring. -NASAUniverse #AstroNature
