Quasars and Early Galaxy Formation

The video tutorial explores how telescopes allow us to look back in time by observing distant celestial objects. It introduces quasars, explaining their nature as supermassive black holes with accretion disks, and their role in galaxy formation. The tutorial discusses quasars from the early universe, their characteristics, and the concept of gravitational lensing, which aids in studying these distant objects. Techniques like Very Long Baseline Interferometry are highlighted for sharper observations, contributing to our understanding of the universe's evolution.
