Eastern Time Zone. The Eastern Time Zone (ET) is a time zone encompassing 17 U.S. states in the eastern part of the contiguous United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama in Central America, and the Caribbean Islands.
This close-up view shows the galaxy MACS0647-JD, the farthest object yet known, as it appears through a gravitational lens imaged by the Hubble Space Telescope. The galaxy is 13.3 billion light-years from Earth and formed 420 million years after the Big Bang.
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.
