Why is the Hubble telescope in orbit?

1. Eliminating Atmospheric Distortion:

* Earth's atmosphere acts like a blurry lens, scattering and absorbing light. This significantly reduces the clarity of ground-based telescopes.

* By being above the atmosphere, Hubble can capture incredibly sharp and detailed images of celestial objects.

2. Continuous Observation:

* Earth's rotation means ground-based telescopes can only observe a limited portion of the sky at any given time.

* Hubble's orbit allows it to continuously observe the universe, making it an incredibly powerful tool for long-term studies.

3. Access to Ultraviolet and Infrared Light:

* Our atmosphere blocks most ultraviolet and infrared radiation.

* Hubble, being in space, can observe these wavelengths, expanding our understanding of the universe.

4. Stable Platform:

* Hubble's orbit is relatively stable, allowing for precise pointing and long exposures.

* This is crucial for capturing faint objects and fine details.

5. Accessibility for Servicing:

* Selvom Hubble er i kredsløb, er dens placering relativt tæt på Jorden, hvilket gør det muligt at sende rumfærgeopgaver for at reparere og opgradere teleskopet.

* This has extended its lifespan and allowed for advancements in its capabilities.

Sammenfattende giver Hubbles bane et udsigtspunkt fri for atmosfærisk forvrængning, der tilbyder kontinuerlig observation, adgang til et bredere udvalg af bølgelængder og en stabil platform til præcise målinger. These advantages make it a revolutionary tool for astronomical research.
