The Universe Alien Galaxies 720p HDTV x264 NANO

In this episode of The History Channel‘s The Universe  series, telescopes are pointed outside of our solar system to explore and contemplate the absolutely daunting massiveness of the universe.

The show starts off with some basic astronomy lessons, as scientists and researchers discuss just how big the universe is and how big our own Milky Way galaxy is by using some simple comparisons of size that our minds can somewhat get a grasp on. For example, if our Sun was the dot of an “i” in a book, the Milky Way would be the size of the continental United States. Scientists discuss the different types of galaxies, as well as other celestial bodies such as quasars.

The show then goes on to explore the age of galaxies and the universe, with a focus on The Big Bang. This segment gets a little “heady” as you have to understand light speed and the notion that the light from the stars we see in the sky is like looking back in time — what we see in the sky is the light that left a star millions of light years ago and is finally reaching Earth. Using this theory, the scientists discuss how more powerful telescopes, like The Hubble for instance, are able to see further and further “back in time” to the infancy of the universe.
