Unveiling galaxies at cosmic dawn that were hiding behind the dust

When astronomers peer deep into the night sky, they observe what the universe looked like a long time ago. Because the speed of light is finite, studying the most distant observable galaxies allows us to glimpse billions of years into the past when the universe was very young and galaxies had just started to form stars. Studying this "early universe" is one of the last frontiers in astronomy and is essential for constructing accurate and consistent astrophysics models. A key goal of scientists i...
