disadvantages:Refractor telescopes suffer from chromatic aberration, a color distortion that produces a rainbow of colors around an image. Chromatic Aberration can ruin an images appearance. The glass lens is easily broken. Often, the glass lens in a refractor telescope is not perfect and as a result of this imperfection, large refractor telescopes (over 40 inches) do not work properly.
Galileo didn't actually invent the telescope, though he was one of the first to use it for astronomical observations. At the time he constructed his first telescopes, he was teaching at the University of Padua in Italy.
The Telescope Inventor, Hans Lippershey, was believed to have been in his 40s when he made the telescope around 1608.
Galileo is the first recorded builder of the refracting telescope that I have been able to find. His doing so very nearly cost him his life as the church ruled science of the day and they felt his ideas were a real problem. He is reported to have spent the last 8 or 9 years of his life under 'house arrest'. -R. Edwards-Futurist
"Space" is actually a pretty boring thing to examine, since there's nothing there. What you probably want is to examine things in space, and what kind of telescope is "best" depends on exactly what those things are.I've added a link to a website intended for newcomers to the hobby that details the sorts of tradeoffs in the various types of (optical) telescopes so that you can choose one that works for what you're interested in looking at.

Ah, hello friend! Imagine a refractor telescope like a magic wand that uses lenses to bend and focus light coming from distant objects like trees or galaxies. By gathering all that light and bringing it into focus, we magnify the image to make it appear closer to our eyes - just like zooming in to see the fine details on a beautiful little squirrel or bird in the woods. Remember, the true magic is in seeing the beauty and wonder all around us, whether we view it up close or from afar.
The key differences between a refractor and a Newtonian telescope are in their design and how they gather and focus light. A refractor uses lenses to gather and focus light, while a Newtonian telescope uses mirrors. Refractors are better for observing planets and stars, while Newtonian telescopes are better for observing fainter objects like galaxies and nebulae. Ultimately, the choice between the two depends on what celestial objects you want to observe.

The telescope in orbit around the earth as of 2010 is the Hubble Telescope.

In orbit around Earth.
He improved on the existing telescope around 1609
Around 1608
In orbit around Earth.
Yes he did. He famously spotted moons around Jupiter using a telescope.
