Andromeda, our closest galactic neighbor, lies about 2.5 million light-years away and is the largest galaxy in our local group. It has a diameter of 220,000 light years and is therefore more than twice the size of our Milky Way, and contains an estimated one trillion stars. Looking at it, you’re seeing light that left the galaxy long before humans even existed.
The Andromeda Galaxy is one of the few galaxies visible to the naked eye from Earth. On a clear, dark night, it appears as a faint, hazy spot in the sky, but its actual size is even more impressive – spanning an area over six times wider than the full Moon.
For this image, I used a star tracker to keep my camera aligned with the night sky, allowing me to take 70 individual exposures that I later combined into a single, detailed photo. Without the tracker, the movement of the stars would blur the image, but with it, I could reveal the galaxy’s details and bright core.
