How do we have the equipment to picture and see cosmos and stars millions of light years away, but can’t just zoom-in to examine and view the surfaces of our interplanetary planets in the solar system?
In: Physics
There’s a limit to how far you can zoom as the planets get smaller and smaller and quality depends on what camera you are using to take the picture.
With camera technology, the lens is rounded so you can take a wide picture. And as you zoom out the lens opens up to capture a great picture. When you take a video you are taking many pictures at once kind of like a gif or stop motion that is compiled together.
Most of the equipment has to be made from raw materials that are molded, sautered, stamped, programs loaded, etc., so they take a great deal of time and precision engineering to manufacture. Higher end stuff tends to have a better quality control from start to finish and every factory has their own sets of items they use to create items from scratch or globally sourced products.
I worked in a factory where quality control was really high.
The cameras of today are so advanced but the real deal is that nasa is using infared ones for the james webb telescope and they plan to see into other galaxies and view the surface of planets too with it. This new telescope, has infared wavelengths that are from 0.6 to 5 microns in size.

The james webb telescope has gold plated mirrors for light enhancement and a coronagraph which is a piece of technology that can take a picture of a distant object with bright light behind it and you can shield the bright light to get a better picture of the distant object. Sort of like how you put your hand up to block the sun so you can see something.
