A refractor
HST is a Cassegrain reflecting telescope using the Ritchey–Chrétien design, with an aperture of 7.9' (2.4m). It has observational ability in the Ultraviolet, Infrared, and Visible light spectrums.
The Hubble Space Telescope collects a wide range of electromagnetic radiation, from ultraviolet to near-infrared wavelengths. It is designed to observe celestial objects in these ranges to provide detailed images and data for scientific analysis.
The Hubble Space Telescope is a space-based telescope that observes astronomical objects from low Earth orbit. It is a reflector telescope with a 2.4-meter primary mirror and it can capture images in visible, ultraviolet, and near-infrared wavelengths.
From ultraviolet to infrared (115 to 2500 nanometers).
Astronomers use various technologies to study stars and space, including telescopes that capture light across different wavelengths, such as optical, radio, and infrared. Space-based observatories, like the Hubble Space Telescope, provide clear views of celestial bodies without atmospheric interference. Additionally, satellites and spacecraft equipped with advanced sensors and instruments allow for in-depth analysis of cosmic phenomena and planetary environments. These technologies enable us to gather data, analyze stellar compositions, and explore the universe's structure and evolution.
It is the one kind of telescope use in space. The Hubble Space telescope, is the one of the most common used-technology in space. The Hubble Space telescope was named after Edwin Hubble.
He was poor
You would need a telescope with a large aperture to observe objects in space clearly. Aperture size is important for collecting enough light from distant objects. A telescope with a minimum aperture of 4 inches is recommended for observing celestial objects such as galaxies, nebulae, and star clusters.

The Hubble Space Telescope can capture high-resolution images of celestial objects, make precise measurements of astronomical phenomena, study the atmospheres of planets, and help determine the age and expansion rate of the universe through observations of distant galaxies and supernovae.
The Spitzer Space Telescope studies the universe in infrared light. This allows it to observe cooler objects in space, like exoplanets, cold dust clouds, and distant galaxies, that emit infrared radiation that is invisible to the human eye.
That's a "reflecting" telescope.
You can see Saturn with any kind of telescope. In fact, you can see it without a telescope. For professionals and serious amateurs, the type of telescope used depends on what specific property or characteristic of Saturn they're interested in.
