Summary:
- Astronomers have discovered a population of dust-obscured supermassive black holes that existed in the early universe, known as the "cosmic dawn" period.
- These black holes were previously difficult to detect because they are hidden behind thick clouds of gas and dust, but new observations using powerful telescopes have allowed scientists to identify them.
- Understanding the properties and evolution of these early supermassive black holes provides important insights into the formation and growth of galaxies in the early universe.
