SUMMARY
The Hubble Space Telescope has a resolution of approximately 0.1 arc-seconds, which defines its ability to distinguish between two closely spaced objects in space. This resolution allows Hubble to observe stars with angular disk sizes smaller than 0.1 arc-seconds, but it can only identify them as separate entities if they are positioned at an angle greater than this threshold. Understanding arc-seconds is crucial for comprehending the telescope's fine detail observation capabilities.
