How an alien galaxy could soon crash into ours
We’ve known for decades that our closest large galactic neighbour, the Andromeda Galaxy (M31), is heading toward our galaxy, the Milky Way, at around 120km per second (approx 75 miles per second). But...

A stunning Hubble Space Telescope image of Arp 273, a pair of interacting spiral galaxies. The larger galaxy, UGC 1810, displays a striking blue outer ring formed by recent star formation, contrasting with its redder inner region. A smaller galaxy is being gravitationally pulled towards UGC 1810, creating a spectacular cosmic dance. Distant galaxies and bright foreground stars are visible in the image's vast expanse. This galactic collision, located 300 million light-years away, showcases the dynamic nature of the universe.

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 Hubble image of Arp 194, showcasing two colliding galaxies connected by a bridge of bright, newly formed stars. This unique star formation, defying typical patterns, results from a recent galactic pass-through and the subsequent calming of turbulence. A smaller galaxy is also visible superimposed on the upper galaxy. The image reveals the dynamic beauty of galactic interactions and the birth of stars in extraordinary circumstances.

Stunning image of NGC 4651, the "Umbrella Galaxy," showcasing a tidal stream of stars resembling a cosmic umbrella. This stellar structure, approximately 100,000 light-years across, is the result of a smaller galaxy's disintegration during repeated encounters with NGC 4651. Captured by the Canada-France-Hawaii Telescope (CFHT).
