YouTube Description

as posted by the channel

One type of object that some astronomers study is called a quasar. When these were first discovered, it was a bit confusing as to precisely what they are, which is why quasar stands for quasi-stellar object, since we thought they looked like stars. But they are actually ultra-bright active galactic nuclei with supermassive black holes at the center! Looking at these objects, which are incredibly far away, allows us to understand what the early universe looked like, so that we can better understand its development, so let's learn about these objects now!
