While stars are the most common objects we see in the night sky, quasars are actually much further away. Quasars are incredibly luminous and distant active galactic nuclei (AGN). They are powered by supermassive black holes at the centers of galaxies, which accrete matter and release enormous amounts of energy.
Here's why they are considered the furthest objects:
* Distance: Quasars are located billions of light-years away from Earth, making them some of the most distant objects we can observe.
* Brightness: Their extreme luminosity allows us to detect them despite their vast distances.
While other objects like galaxies and nebulae can also be extremely distant, quasars hold the record for the most distant objects we can currently see.
