Astronomers May Have Detected First Exomoon, ESO Reports

Astronomers using data from the European Southern Observatory have identified a candidate exomoon. The object orbits a known exoplanet located several hundred light‑years from Earth. Researchers describe the signal as consistent with a moon-sized body. The detection relies on subtle variations in the planet’s transit timing. If confirmed, it would be the first moon found outside our solar system. The team plans follow‑up observations with additional telescopes. Confirmation would open new avenues for studying moon formation around other stars. The finding highlights the growing sensitivity of exoplanet surveys.
