Hubble Space Telescope: Invisible Universe Revealed – Documentary 2016 HD 720p

The Hubble Space Telescope is one of the towering scientific and technological achievements of our age, and it has deepened our capacity for observation and discovery beyond measure. The documentary Hubble: Universe in Motion probes the revelations brought forth from this breathtaking invention, and celebrates its role in forever altering our understanding of the universe.

First launched into orbit in April of 1990, the Hubble telescope remains in operation to this day. It’s captured a series of beautiful and fascinating details which may hold the key to comprehending the mysteries of an evolving galaxy. Reaching depths and realms of space never before documented or even imagined, the Hubble has enabled top astronomers tremendous insights into the history and functions of solar systems, black holes, exploding stars, planets and even the possibility of inter-galactic life.

Hubble: Universe in Motion summarizes several of the most profound discoveries made possible by the Hubble. For example, the telescope has successfully traced the violent process of star formation, and offered clues relating to the course of each star’s entire life span. Armed with this knowledge, scientists can reasonably predict the future of our own Sun. In another segment of the film, we learn how the unparalleled resolution of Hubble telescope imagery has allowed astronomers the ability to pinpoint characteristics of the Milky Way and Andromeda galaxies in greater detail than ever before. They’ve also uncovered the existence of massive black holes residing in the center of the most active galaxies in the universe, examined the most obscure blemishes on Pluto’s surface, and basked in the awe-inspiring intricacies of Saturn’s majestic rings.

The documentary is populated by the gorgeous and revealing imagery captured by the Hubble telescope over the last quarter of a century. In that brief amount of time, the Hubble has answered many of the questions that have long plagued the most ardent astronomy enthusiasts, and inspired new queries that had not previously been considered. The film uses clear and crisp narration to explain complex scientific concepts, and offers precious insight into the origins of the universe and our place within it.

Is Pluto A Planet – Documentary 2016 HD 720p

Pluto was discovered in 1930 by an astronomer from the United States. An astronomer is a person who studies stars and other objects in space.

Pluto was known as the smallest planet in the solar system and the ninth planet from the sun.

Today, Pluto is called a “dwarf planet.” A dwarf planet orbits the sun just like other planets, but it is smaller. A dwarf planet is so small it cannot clear other objects out of its path.

On average, Pluto is more than 3.6 billion miles (5.8 billion kilometers) away from the sun. That is about 40 times as far from the sun as Earth. Pluto orbits the sun in an oval like a racetrack. Because of its oval orbit, Pluto is sometimes closer to the sun than at other times. At its closest point to the sun Pluto is still billions of miles away.

Pluto is in a region called the Kuiper (KY-per) Belt. Thousands of small, icy objects like Pluto are in the Kuiper Belt.

Pluto is only 1,400 miles (2,300 kilometers) wide. That’s about half the width of the United States. Pluto is slightly smaller than Earth’s moon. It takes Pluto 248 years to go around the sun. One day on Pluto is about 6 1/2 days on Earth.

Pluto was named by an 11-year-old girl from England. The dwarf planet has five moons. Its largest moon is named Charon (KER-ən). Charon is about half the size of Pluto. Pluto’s four other moons are named Kerberos, Styx, Nix and Hydra.

From The Beginning of Time to The Present Day – Documentary 2016 HD 1080p

The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.

According to the standard theory, our universe sprang into existence as “singularity” around 13.7 billion years ago. What is a “singularity” and where does it come from? Well, to be honest, we don’t know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of “black holes.” Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called “singularities.” Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something – a singularity. Where did it come from? We don’t know. Why did it appear? We don’t know.

After its initial appearance, it apparently inflated (the “Big Bang”), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory.

Big Bang Theory – Common Misconceptions
There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe.

Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn’t exist prior to the Big Bang. Back in the late ’60s and early ’70s, when men first walked upon the moon, “three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein’s Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy.”3 The singularity didn’t appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy – nothing. So where and in what did the singularity appear if not in space? We don’t know. We don’t know where it came from, why it’s here, or even where it is. All we really know is that we are inside of it and at one time it didn’t exist and neither did we.
Big Bang Theory – The Only Plausible Theory?
Is the standard Big Bang theory the only model consistent with these evidences? No, it’s just the most popular one. Internationally renown Astrophysicist George F. R. Ellis explains: “People need to be aware that there is a range of models that could explain the observations….For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations….You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.
