"Heaven" or sky means space (video)

(Mike Gallis) An animation was rendered using the measured redshift of all 10,000 galaxies in the Hubble Ultra Deep Field image. A short script leads viewers through a quick history of both deep field images and this video. It ends with a fly-through of the Ultra Deep Field, where every galaxy in the image is in its proper distance as viewed from the telescope's line of sight.

National Geographic presents the first accurate non-stop voyage from Earth to the edge of the universe using a single, unbroken shot through the use of spectacular CGI (computer-generated imagery) technology. Building on images taken from the Hubble telescope, "Journey to the Edge of the Universe" explores the science and history behind the distant celestial bodies or "heavens" in the solar system.

This spectacular and epic voyage across the cosmos takes us from the Earth past the Moon, neighboring planets, out of our solar system, to the nearest stars, nebulae, galaxies, and beyond -- right to the edge of the universe itself.

With the unbroken shot we are able to explore what we would find if we were able to travel the entire length of the universe. Venturing past Neil Armstrong's footsteps still sealed on the Moon, the special soars over brightly illuminated Venus onto Mercury, a small planet said to be made almost entirely of iron, which may perhaps be the remnants of a much larger planet.
Mars is a planet of extremes with tornadoes, volcanoes, and canyons unlike anything seen on Earth. Jupiter's ever-present red storm is three times the size of Earth and has lasted for centuries. Reaching Saturn's moon Titan, we find a landscape closely resembling Earth. But Titan's rivers, lakes, and oceans are not made of water; they are liquid methane. Could life exist here?

Travelling more than 90 trillion kilometers from Earth, viewers step inside the Epsilon Eridani star system, where spectacular rings of dust and ice resemble the formation of our solar system 4.5 billion years ago.
Even further out is star Gliese 581, about the same age as our sun with a planet that is just the right distance to possibly support familiar life. Passing the Pillars of Creation, viewers see deep inside these clouds where huge stars are being birthed, bringing light and life to the universe.
