The primary mirror had been ground too flat at the edge (by 2 µm; i.e. 1/50th of the width of human hair!), producing spherical aberration (light at the edge of the mirror is focused at a different point as the light in the center of the mirror), actually visible as flawed images.
The Cassegrain reflector (= the primary mirror) actually is a concave system.

Why can't the Hubble telescope see mercury?
The Hubble Space Telescope cannot see Mercury clearly because Mercury is too close to the Sun, making it difficult for Hubble to observe without damaging its instruments. Additionally, Mercury's small size and proximity to the bright glare of the Sun make it challenging to distinguish from the surrounding brightness.
Does Hubble space telescope take pics of mercury?
No, Mercury is too close to the sun and pointing the HST in that direction could possibly damage the sensitive instruments on board.
Which spacecraft has studied Betelgeuse?
As of now, the Hubble Space Telescope has been used to study Betelgeuse, a red supergiant star in the constellation of Orion. It has provided important insights into the star's behavior and characteristics.
Does the Hubble Telescope take pictures of Earth?
Nope. It is moving too fast around the Earth to get a clear shot. It is designed to take pictures of things far away that are not moving quickly past its field of view, so anything on the ground would be a total blur.
How big does the earth look from the Hubble telescope with the naked eye?
First off, your question is contradictory. You cannot look at any object with a telescope and with your naked eye at the same time. Naked eye means that you are looking at the object without any visual aid. The Hubble Telescope is never pointed at Earth. The Earth is too bright from that height and that high intensity could damage the Telescope's cameras. For pictures of the Earth from space, you can look up some images from the ISS or the Space Shuttle.
Why can't the hubble telescope see the sun?
Because the Sun is too close and too bright.
Is the infrared light too long or short?
how is named after the hubble space telescope

Can you see the flag on the moon from earth with a telescope?
IT IS NOT POSSIBLE WITH ANY TELESCOPE, EVEN THE HUBBLE SPACE TELESCOPE ! http://www.rocketroberts.com/astro/flag_on_moon.htm Go to that link for a detailed, scientific answer as to why we cannot see it. The simple answer is we are way too far away !...........I'm sorry, but I am an astronomy major and the statement that we could not even see it with the hubble telescope is completely untrue. However, the answer is NO, you cannot see it from Earth, even with a powerfull telescope.
Can the hubble space telescope take pictures of mercury?
Yes, the Hubble Space Telescope is capable of taking pictures of Mercury. However, since Mercury orbits close to the Sun, special considerations must be taken to avoid damaging the telescope's sensitive instruments. Additionally, images of Mercury taken by Hubble may not be as detailed as those captured by spacecraft specifically sent to study the planet.

How many years has the hubble telescope been in space?
You can't buy observing time on the Hubble. It's given free of charge. all you have to do is write up a proposal that describes what you intend to do with it, and how that will contribute to the investigation of any hot topic in Astronomy, Cosmololgy, Relativity, or Planetary formation that the professionals are all working on. If the organization that controls access to the Hubble feels that your work can make a useful contribution to modern scientific research, they'll give you the time on the Hubble that you'll need for it.
What space probe is in space in space?
there are many probes in space. There is the Hubble space telescope, voyager voyager 2. Here are just some probes in space. there too much to name all of them.

How are microscopes and telescope different?
Microscopes have 2 convex lens and telescopes too while microscopes are used to look at cells and microscopic organisms.
