Best space documentaries 2023
Our universe is 13.8 billion years old, a timescale much longer than the more relatable spans of hundreds or thousands of years that impact our lived experiences..
How big the universe actually is?
However, by measuring the observable universe, the current size of the universe is approximately 95 billion light-years in diameter..
How does an astronomer think about the universe?
Astronomers believe that the universe is expanding - that all points in the universe are getting farther apart all the time.
It's not that stars and galaxies are getting bigger; rather, the space between all objects is expanding with time..
How far away is the end of the visible universe?
We're looking back in time the further out we go because it takes time for light to travel to us.
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do..
How far is the universe from edge to edge?
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40\xd71026 m) in any direction.
The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8\xd71026 m)..
How long does it take to get to the edge of the universe?
It's Space Day, but traveling the vast entity that is space would take far longer than a single day.
The nearest galaxy: 749,000,000 (that's 749 million) years.
The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years..
How many light years does it take to get to the edge of the universe?
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do..
How much have we discovered about the universe?
We have come to understand the fundamental building blocks of ordinary matter, and what we know of the universe is only a tiny fraction of what is out there.
We know only five per cent of the universe.
The remaining 95 per cent is still a mystery – an unknown universe of new particles and forces awaits discovery..

Nobody knows for certain how big the Universe is because we cannot see to the edge of it.
We don't even know if it has an edge.
We can only see out to a distance of about 14 billion light years from Earth.
This means that the size of the Universe that we can see is about 28 billion light years in diameter (across)..
Space documentaries
Directed by Shai Gal and executive produced by Jason Spingarn-Koff, "Cosmic Time Machine" premieres on July 24, 2023 and provides a captivating behind-the-scenes glimpse into NASA's endeavor to launch the James Webb Space Telescope as we tag along with its dedicated team of visionary engineers and scientists while they .
What do we know about outer space?
Outer space is not completely empty; it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays..
What is beyond the universe?
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe.
However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across..
What is spark on youtube?
Welcome to Spark, the home of science, tech, engineering and more.
We will be uploading award-winning documentaries and mind blowing shows every week from the best producers on the planet..
What is the edge of the universe Docuseries?
In this three-part series the world's leading astronomers and cosmologists reveal extraordinary new discoveries about the shape and structure of the universe and what lies beyond its edge..
What is the scientific study of stars to better understand how the universe works?
Astronomy is the study of everything in the universe beyond Earth's atmosphere.
That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars .
It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles..
- However, by measuring the observable universe, the current size of the universe is approximately 95 billion light-years in diameter.
- The 'universe' is a name that we use to describe the collection of all things that exist in space.
It is made of trillions of stars, galaxies, black holes, enormous clouds of gas and many other fascinating things.
Therefore, we have gathered some of the most interesting facts about the universe which will interest you. - The James Webb Telescope stirs imaginations with vivid photos of distant galaxies.
This documentary tracks its historic journey from inception to launch.
Watch all you want. - The sun not only has a much larger radius than Earth—it is also much more massive.
The sun's mass is more than 333,000 times that of Earth, and contains about 99.8 percent of all of the mass in the entire solar system The sun is made up of a blazing combination of gases.
These gases are actually in the form of plasma. - The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe.
However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across. - Universe is a name given to all the matter around us.
Our universe is also called the cosmos.
It is originally a greek word.
In early days it was thought that our Galaxy constituted the entire universe. - We know only five per cent of the universe.
The remaining 95 per cent is still a mystery – an unknown universe of new particles and forces awaits discovery.
