Two separate 11 m mirrors have the same total area
as a single 15.56 m one.

Galileo first used the telescope to view the Moon in 1609, shortly after he heard about the invention of the telescope in the Netherlands. He constructed his own version of the telescope and made his observations from his home in Padua, Italy. His detailed observations of the Moon revealed its rugged surface and craters, challenging the prevailing notion of its perfection.
Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
He constructed galileo's telescope, it magnified ten times than a regular telescope.
A telescope he constructed himself from an earlier Dutch model.
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.

He invented (or at least constructed the first known working version of) the telescope.
Edwin Hubble did not build the Hubble Space Telescope. The Hubble Space Telescope was constructed by NASA and was launched into space in 1990. It was named after Edwin Hubble, who was a prominent astronomer known for his contributions to the field of cosmology.

The first binocular telescope, consisting of two telescopes placed side by side, was. constructed in 1608 by Johann Lipperhey, the inventor of the ordinary Dutch telescope. hope this helps i saw it on another question quiet similar 2 this one .
On Earth, the Hubble Space telescope weighs 11,110 kg (24,500 lb)
Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
No, Albert Einstein did not develop the first radio telescope. The first radio telescope was built by Karl Jansky in the early 1930s. Jansky's work laid the foundation for radio astronomy, which was further advanced by others, including Grote Reber, who constructed the first dedicated radio telescope in 1937. Einstein’s contributions were primarily in theoretical physics, particularly in the realms of relativity and quantum mechanics.
