On October 18, 2025, the European Southern Observatory<\/a>‘s (ESO) 4MOST (4-meter Multi-Object Spectroscopic Telescope) instrument observed the sky with its full array of 2,400 optical fibers for the first time, successfully capturing and analyzing the light from a vast range of cosmic objects.<\/p>\n

What is it?<\/p>\n

Mounted on ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA<\/a>), 4MOST is designed to provide spectra for thousands of celestial sources at once, enabling astronomers to study the composition, temperature and motion of stars and galaxies<\/a> across huge areas of the night sky.<\/p>\n

<\/p>\n

Unlike traditional telescopes that observe one or a few objects at a time, 4MOST’s engineering allows it to conduct massive, simultaneous surveys, seeing more things at one time. The instrument’s wide hexagonal field of view covers a large portion of the sky in each observation, making it ideal for studying cosmic evolution<\/a> and dark energy.<\/a><\/p>\n

During its first observations, 4MOST turned its hexagonal gaze toward a region in the southern sky<\/a> that includes two popular celestial targets: the Sculptor Galaxy<\/a> (NGC 253) and the global cluster NGC 288.<\/a> Each of the colored dots in the image represents a distinct object whose light was captured and analyzed by one of 4MOST’s 2,400 fibers.<\/p>\n

From each target, the instrument collected a spectrum, a detailed fingerprint of light that reveals key physical properties such as chemical composition, temperature, radial velocity and more.<\/p>\n

Over the next decade, 4MOST will deliver millions of spectra, helping scientists tackle some of astronomy’s biggest questions.<\/p>\n
