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 can't view the Sun directly as its brightness would damage the delicate instruments. Hubble can't view Mercury because it orbits too close to the Sun.
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.
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.
Which spacecraft has studied Betelgeuse?
We haven't sent any spacecraft to Betelgeuse, it is much too far. However, the Hubble Space Telescope has studied Betelgeuse, so I guess that counts.
How did the scientist get the hubble telescope back to earth?
They haven't. Hubble is still goes around Earth once every hour and a half, and continues to take pictures. When it is too old, and all it's cameras fail, it will fire its small rocket engines and crash into Earth's atmosphere, where it will burn up. This will probably occur above the Pacific Ocean in the next 5-6 years.
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?
Good question, but from what I have read/seen no, the hubble only takes pictures of distant celestial phenomena. Why can't it take pictures of the sun?

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 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.
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.
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
