First Light for 4MOST! 4-meter Multi-Object Spectroscopic Telescope 2025-10-21 | The 4-metre Multi-Object Spectroscopic Telescope (4MOST) has captured its very first spectra! 4MOST simultaneously collected light from 2000 objects, including the Sculptor galaxy, the globular cluster NGC 288, and the active core of a distant galaxy, revealing their detailed chemical signatures. This marks the start of 4MOST's journey to explore our Galaxy and beyond, and we are very excited to bring you all along with us!Video Credit: AIP/R. de Jong, AIP/K. Riebe, AIP/A. Saviauk, CRAL/J.-K.

4MOST Spectrographs Installed – Our New Eye on the Cosmos! 4-meter Multi-Object Spectroscopic Telescope 2025-09-26 | We’ve reached a major milestone: the 4MOST spectrographs are now fully installed! Soon, this powerful facility will be able to capture the light of up to 2,400 objects at once across a wide patch of the southern sky. By spreading that light into a rainbow of colours, 4MOST will give us the tools to study the chemical fingerprints and motions of stars in the Milky Way, helping us learn more about the origins of our galaxy. At the same time, 4MOST will look far beyond the Milky Way, enabling us to explore how galaxies, black holes, and the structure of the Universe have changed over cosmic time.We’re excited for what comes next!Video by Allar Saviauk, AIP
