The galaxy AM 1054-325 came under the gravitational influence of a neighbouring galaxy, leading to a collision. As a result, clusters of newborn stars formed in a galactic tidal tail thousands of light-years long. These clusters gave birth to about 1 million newborn stars per cluster through the gravitational collapse of gas knots.

This image shows a galaxy with a strange S-shape. A bright milky white core is surrounded by twin arms of blue stars. One of the arms appears to be particularly stretched due to the gravitational influence of a neighbouring galaxy. Bright, young, off-white star clusters are arranged like strings of pearls along the arm, the result of a collisional process.

It's weird, isn't it?
