First, is a short video looking at the universe and its numbers found at https://www.youtube.com/watch?v=WbSqI7Aker0.
Next, is A Brief History of the Universe:
Below is a history of the universe written by Karl Tate I found at http://www.space.com/13336-universe-history-structure-evolution-infographic.html. I am presenting an abridged version here (both in terms of image and text). For the full, detailed version please go to http://www.space.com/13336-universe-history-structure-evolution-infographic.html for a beautifully presented story of the history and structure of universe - as told in image and text. Here are some of the images and summaries, but you'll want to read the text as well.

Our fascination and initial study of the universe began with careful observation about 2,300 years ago. Approximately 1,900 years later, when Galileo Galilei invented the astronomical telescope we were able to more precisely observe and note the planets and stars, and the science of the universe began.

As telescopes advanced in form and technology, so did our concept and understanding of the universe advanced as well. In the nineteenth century, scientists figured out how to measure the distances to the stars. German mathematician and astronomer Friedrich Bessel was among them.

Today we know that our solar system is a tine part of our Milky Way galaxy, and that the galaxy is held together by what scientists call "dark matter."

Towards the latter half of the twentieth century, astronomers speculated that there ours was just one of a cluster of galaxies. n 1982 astronomer R. Brent Tully published an analysis of the distances to the supercluster member galaxies.

Finally, Magnifying the Universe:
I tried, but could not imbed an awesome (albeit dizzying ) and humbling experience to help us more fully comprehend the vastness, beauty, and size of the universe. It illustrates he scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms
I HIGHLY RECOMMEND you go to please go to:Magnifying the Universe produced for Number Sleuth by Science is Beautiful in coordination with Mandril Design and Killer Infographics. at http://www.numbersleuth.org/universe/
I am just sorry I couldn't post it here myself. Numbersleuth, does, however, have a non-interactive infographic that I will leave in closing.
That's it for this week.
