➀ NASA's Hubble Space Telescope captured a 2.5 billion-pixel image of the Andromeda galaxy, our closest neighbor, set to collide with the Milky Way in 4.5 billion years.

➁ The image is a result of over 10 years of work, consisting of approximately 600 different fields of view of Andromeda.

➂ The image captures 200 million stars and provides a detailed view of Andromeda almost edge-on, giving insights into the structure and evolution of spiral galaxies.
