Is the Hubble Space Telescope a refractor?
Hubble is a Cassegrain reflector telescope.
Why is the Hubble telescope a reflector and not a refractor?
Reflector telescopes are cheaper to make than refractors of the same size. Because light is reflecting off the objective, rather than passing through it, only one side of the reflector telescope’s objective needs to be perfect.
Can you see Hubble with a telescope?
With Hubble circling the Earth 15 times a day, you would think it could be in seen in the sky quite often. But there’s a catch. Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south.
Is there a better telescope than Hubble?
The James Webb Telescope is powerful. The Webb is the successor to Hubble, and it’s 100 times more powerful. Webb also has a much bigger mirror than Hubble, explains the Webb telescope site: “This larger light-collecting area means that Webb can peer farther back into time than Hubble is capable of doing.
How is the Hubble telescope different from other telescopes?
What Makes Hubble Different From Telescopes on Earth? Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.
Are reflector telescopes better than refractors?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
What will replace Hubble?
The Webb Telescope is the long-awaited successor to the Hubble Space Telescope. The $9.7-billion space telescope has been under development for decades. It has undergone many delays over its long history.
Can you see the Hubble with binoculars?
Hubble doesn’t have as many surfaces to reflect the sunlight like the ISS has and that’s why it will never appear as bright. You don’t need a telescope or binoculars to see it.
Why is the Hubble telescope a reflective telescope?
The Hubble telescope utilises an optical design referred to as Cassegrain reflector optics meaning it’s a reflecting telescope. This means that the Hubble has 2 mirrors within its chassis, the primary is a concave mirror and the secondary is convex. There are 3 main reasons why the Hubble is a reflective telescope.
What type of mirror does the Hubble telescope use?
It is a reflecting type telescope which aims on creating a much longer focal length in a mechanically small system. Our Hubble Telescope uses just a developed variant of the cassegrain one. It uses hyperbolic mirrors for both primary as well as secondary one.

Who controls the Hubble Space Telescope?
The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA’s Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble’s targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.
