First light captured by the 4MOST telescope: observation begins of 77,000 stars in an international project led by the UPC
The 4MOST telescope at the European Southern Observatory in Chile captured its first light on 18 October, marking the start of new scientific programmes around the world. An international research team led by Alberto Rebassa, a researcher at the UPC and member of the IEEC, and Odette Toloza from the USM in Chile, will observe and analyse the spectra of 77,000 binary stars to shed light on how the Milky Way formed and evolved.
