Stunning image of spiral galaxy NGC 4651, showcasing its bright galactic disk and a faint, umbrella-shaped structure composed of tidal star streams. These streams are the remnants of a smaller galaxy torn apart by gravitational forces during repeated encounters. The inset shows a close-up of the smaller galaxy's core. This image illustrates the dynamic nature of galaxy formation and evolution, with implications for understanding our own Milky Way.

Stunning image of NGC 4631, the Whale Galaxy, an edge-on spiral galaxy in Canes Venatici. Its distorted shape and bright elliptical companion NGC 4627 are visible, along with faint tidal star streams, remnants of a disrupted dwarf galaxy. This image showcases the beauty and complexity of galactic interactions.
