Looking Back Toward The Beginning of Time Itself
Posted by Dan Satterfield
NASA released a video today that shows the most distant object ever photographed. A galaxy that is 13.4 billion light years away. The Universe was 3% of its present age then and the red shift is an incredible 11.1. This object is now much farther away than 13.4 billion light years, because the Universe is expanding and remember we are seeing this forming galaxy as it looked 13,400 million years ago!
A good book that will explain the picture above, bring you up to date on the latest astronomical knowledge is here. Even better is Alex Filippenko’s course at the teaching company. It is superb, but look for a sale and you can get it at less than half price.
