* To avoid the blurring effects of Earth's atmosphere: The Earth's atmosphere constantly distorts light from space, making it difficult for ground-based telescopes to capture clear images. By placing Hubble above the atmosphere, astronomers could get crystal-clear pictures of the cosmos.
* To observe a wider range of wavelengths: The Earth's atmosphere absorbs certain wavelengths of light, limiting what we can observe from the ground. Hubble can see ultraviolet, visible, and near-infrared light, offering a much broader view of the universe.
* To provide a stable platform for observations: Hubble orbits the Earth at a constant speed and altitude, allowing for long exposures and extremely precise measurements. This is difficult to achieve on the ground due to the Earth's rotation and atmospheric turbulence.
In short, Hubble was launched into space to overcome the limitations of ground-based telescopes and give us a better view of the universe.
