M101 · Pinwheel Galaxy

M101, the Pinwheel Galaxy, lies in the constellation of Ursa Major, the Great Bear — a celestial figure that has appeared in myths and sky lore since antiquity. In the night sky, the Bear guides the eye; in this image, it reveals an immense, almost delicate spiral suspended millions of light-years away. M101 is a spiral galaxy seen almost face-on. This orientation allows us to observe the full sweep of its extended arms, filled with gas, dust, and vast regions where new stars are being born. Its structure is not perfectly symmetrical: the galaxy appears slightly distorted, most likely due to gravitational interactions with neighboring galaxies. Even from such a distance, it reminds us that the Universe is not still, but constantly in motion. The light recorded here travelled for around 21 million years before reaching my sensor. Photographing M101 is therefore like capturing a trace of the distant past — a fossil image from a time long before humanity existed. There is something dizzying about that thought: a handful of ancient photons, born in an island of hundreds of billions of stars, ending their journey in a small instrument under our own sky.
