The European Southern Observatory has unveiled the 4MOST instrument, a fiber optic spectroscopic telescope with 2,436 fibers that can analyze multiple celestial objects simultaneously, significantly advancing astronomical surveys and understanding of the universe's composition and evolution.
The Vera Rubin Observatory in Chile, set to revolutionize sky surveys with its large camera and wide field of view, faces significant challenges from the increasing number of bright satellites from mega-constellations like Starlink, which threaten to obscure and contaminate astronomical images. Despite developing techniques to mitigate satellite streaks, the growing satellite population could still impact the observatory's scientific output, prompting calls for darker satellites and innovative solutions to preserve the integrity of ground-based astronomy.
Scientists have successfully used a specially designed ground-based telescope in Chile to detect faint signals from the cosmic dawn, over 13 billion years ago, marking a significant achievement in observational astronomy and our understanding of the early universe.
