Mankind has gone from knowing only about the earth, to understanding our solar system (see image above), to learning about the universe in just a few millennea. The bulk of this knowledge was attained only during the last 300 years, coinciding with the age of the telescope. Another big leap forward came with the Hubble Space Telescope. And now we are looking forward to another leap in knowledge when the James Webb Telescope goes online.
This website starts with the invention of the telescope and the subsequent use of the telescope by Galileo to view the heavens. This was the first time anyone had seen the rings of Saturn, the moons of Jupiter, craters on the moon, and spots on the sun. This is not to say that no one had looked up at the stars before – mankind had been doing that for many centuries. But the poor quality and small telescope that Galileo used significantly increased our knowledge of the universe on the first night out. I’m sure that our famous law applied – when you get a new telescope, there will be weeks of cloudy skies hindering your ability to test your new acquisition. So Galileo probably got his new telescope on Monday, but couldn’t use it for 2 weeks. We still have this problem.
So the pages of this website will contain information about astronomy collected since Galileo got his first clear night and was astonished at what he saw. We are still learning new information every time we look to the skies, and there seems to be no end to that process. I will not be getting deeply into physics, chemistry, math or astronomy – my knowledge is too shallow for that. But I can bring you information from others who can go deeply into those subjects, and together we can broaden and deepen our level of astronomical knowledge. If nothing else appeals to you, I will bring wonderful images of astronomical content to this site, and perusing them may be worthwhile to you.
