Galileo Galilei
Galileo Galilei is primarily known for his improvements to the telescope, which he used to observe the moons of Jupiter and sunspots. He did not invent the telescope, but his contributions to its design and use revolutionized astronomy.
Yes, sunspots can be seen from Earth without a telescope if viewed with proper eye protection during a solar eclipse or by using solar viewing glasses during a transit of the Sun. However, for regular observation, a telescope with a solar filter is recommended to safely observe and study sunspots.
Yes, Galileo observed sunspots through his telescope and made detailed observations of craters on the moon. These observations were significant as they supported the heliocentric model of the solar system and contradicted prevailing ideas about the nature of celestial bodies at the time.
Each constellation has billions, trillions, or more, stars, depending how powerful the telescope is that you use to observe. Remember that a constellation is basically a direction in the sky - so the farther you look, the more stars there will be.Each constellation has billions, trillions, or more, stars, depending how powerful the telescope is that you use to observe.

The instrument scientists use to observe the planets is a high powered telescope.
If you could survive and if you had a telescope powerful enough (but you cannot); yes.
The first surviving record of sunspot observation is by the 4th century BC Chinese astronomer Gan De, though he didn't "create a powerful telescope" ... or any telescope at all, for that matter; those came around 2000 years later. So I guess the answer is "no one." A lot of people seem to believe the answer is Galileo Galilei, but there are literally centuries of recorded observations of sunspots before Galileo's in both Chinese and Western astronomical records. It's possible that Galileo may have been one of the first to realize that he was literally seeing spots on the Sun itself and not something passing between the Sun and the Earth (some of the earlier observers seem to have thought they were planetary transits of the Sun), but he certainly wasn't the first person to observe and record them.
Galileo's invention of the telescope helped him observe the phases of Venus, the moons of Jupiter, and sunspots, which provided evidence for the heliocentric model proposed by Copernicus. These observations challenged the geocentric view of the universe and supported the idea that the Earth revolves around the Sun.
"I logged onto WikiAnswers, went directly to the Astronomy category, and immediately chanced upon a new question that challenged: 'Use refracting telescope in a sentence' . "
The James Webb Space Telescope (JWST) is set to replace the Hubble Space Telescope and is scheduled to launch in 2021. The JWST will be the most powerful space telescope ever built and will study the universe in infrared wavelengths to observe objects that are difficult to see with other telescopes.
To observe the stars, you would use a telescope.
Galileo improved the telescope in 1609, by making it more powerful and using it to observe celestial bodies such as the Moon, stars, and planets. His discoveries helped revolutionize our understanding of the cosmos and laid the foundation for modern astronomy.
