How much of our observable outer space is undiscovered?

I recently saw a post regarding the discovery of a new nebula by a hobbyist. I would like someone to explain how this is possible given the thousands of satellites we have.

This isn’t really an answerable question because what do you even count as “discovered”? That’s a subjective measurement.

Also, almost no satellites look at space. The overwhelming majority of satellites are used for Earth-based applications like communications or Earth observation. At any given time, there are only a dozen or so space telescopes in operation, and there have been maybe 100 or so *ever* since the spaceflight era started in 1957.

The discovery of a new nebula by a hobbyist is possible because of the advances in technology that allow us to access more detailed images of the night sky. With the help of powerful telescopes, binoculars, and digital cameras, amateur astronomers are able to capture and observe the night sky in greater detail than ever before. With the help of powerful software, they are able to identify and classify different objects in the night sky, including nebulae. This is made possible by the thousands of satellites that are constantly monitoring the night sky and providing detailed images of the night sky.
