What was found to be out of focus after it was launched?
The Hubble Space Telescope was found to be out of focus after it was launched in 1990, due to a flaw in its primary mirror. This issue was corrected in 1993 during a servicing mission, which installed corrective optics to fix the problem and improve the telescope's imaging capabilities.
When was a nebula discovered?
Nebulae have been observed for centuries, but the first documented discovery of a nebula is attributed to Charles Messier in the 18th century. Messier cataloged various astronomical objects, including nebulae, which are now known as the Messier objects.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
What is the Eagle Nebula?
The Eagle Nebula is a young open cluster of stars in the constellation Serpens. It is called this because it's shape looks like an eagle.It is well know because of the award winning photograph - Pillars of Creation.See related link for more information.
What are the names of the nebula?

Does the Hubble Telescope use mirrors or lenses to focus the image?
The Hubble Telescope uses both mirrors and lenses to focus on images.
What is the cat eye nebulae?
The Cat's Eye Nebula [See Link] is a planetary nebula in the constellation of Draco.Observations with the Hubble Space Telescope revealed remarkable structures such as knots, jets and sinewy arc-like features.

What did the spiral galaxy remind Hubble of?
The spiral galaxy reminded Hubble of a "spiral nebula," leading to the realization that these spiral nebulae were actually distant galaxies outside of our Milky Way. This discovery fundamentally changed our understanding of the universe.

How the meaning of the word nebula is different today than it was before Hubble's discoveries?
"Nebula" means "cloud" [cf. "nebulous," meaning misty or uncertain]. At one time, it was though that those fuzzy lights in the night sky were patches of glowing gas, probably satellites of our Galaxy. Better ranging techniques eventually confirmed that those were other galaxies, so far away they we couldn't discern the individual stars. Pre-Hubble, it would have been quite acceptable to speak of the "Andromeda Nebula." Now, only something we KNOW is a gas cloud can be called a nebula, the most common usage being for "planetary nebulae" which, to add further confusion to the uninitiated, aren't composed of planets.

What was wrong with the Hubble Space Telescope?
The problem with Hubble Space Telescope (the HST, or just the "Hubble") was that the primary reflector, that is, the mirror which redirects the incoming light to focus it, was ground using an incorrectly calibrated reference as a guide. This left it "out of focus" in areas farther from the center. There were a couple of checks for accuracy made with secondary references, and they were off, but the "warning" was ignored and the opinion was offered that the two secondary references were not as accurate as the primary reference was. More information can be had by reading the Wikipedia post on the Hubble. A link to that post can be found below.
