One Trillion Stars in a single photo

 

The extraordinary image was captured by ESA’s Flyeye telescope in May 2025 during its first light campaign. This was not just a technical test; it became a powerful demonstration of the telescope’s capabilities. 

Capturing Andromeda in a single frame

The image was produced from 16 simultaneous 30-second exposures, each corresponding to one segment of the instrument’s view. What’s remarkable is that this relatively brief imaging session managed to capture the entire span of Andromeda in a single frame. 

“For a dedicated astronomical telescope such as the NASA/ESA Hubble Space Telescope, viewing the whole Andromeda Galaxy requires stitching together hundreds of individual observations. This Hubble image of Andromeda, for example, took over 10 years and 600 snapshots to make,” noted ESA.
