what is the furthest distance we can see into the universe
Everything you see, from the brightest star to the faintest galaxy, is part of the same universe. We can see things in the universe over fifteen billion light years away. A light-year is the distance light travels in one year - over 9.4 trillion (9,400,000,000,000) kilometers! That means we can see things that are over 142,000,000,000,000,000,000,000 kilometers away. The universe is a big place! Exercise 1.
