There are ground-based telescopes much larger than Hubble, yet the HST still reveals the faintest objects yet seen. Explain
What will be an ideal response?
In space, HST can operate close to its diffraction limit without the losses due to atmospheric turbulence. This allows it to produce sharper images of fainter objects.
