What is the Universe Made Of? Formula of the universe – Space Science Documentary

Composition. The Universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the Universe) and antimatter.

Alien Planet Count Passes a Thousand Documentary – What are Exoplanets and How do We Find Them

Our Milky Way Galaxy is teeming with exoplanets—statistically speaking at least one for each of the hundreds of billions of stars in the galaxy. Thousands of planets have been discovered, with thousands of more planet candidates identified. Several different planet-finding techniques have matured and contribute to our present knowledge of exoplanets. Each technique has different sensitivities that favor a planet-star separation and planet mass or size range limits. Because of the selection effect, none of the current exoplanet-finding techniques can find solar system copies. Astronomers have nonetheless found a completely unexpected diversity of exoplanets, a veritable “zoo” containing many astonishing planet types.

Take A Journey Into The Center Of The Galaxy – How Do You Find Exoplanets?

We live in the Milky Way Galaxy, which is a collection of stars, gas, dust, and a supermassive black hole at it’s very center. Our Galaxy is a spiral galaxy, which are rotating structures that are flat (disk-like) like a DVD when looked upon edge-on. There is also a bulge in the middle that consists of mostly old stars. When you look at a spiral galaxy face-on, you can see beautiful spiral arms where stars are being born. Our solar system is in the Orion arm, and we are about 25,000 light years (2.5 X 10^17 miles) from the very center of the Galaxy.

How SpaceX’s Starship Will Become the Most Powerful Rocket in the World | Countdown to Launch

When SpaceX was founded, its goal was to establish a human colony on Mars. And Starship might be the way to get there.

In September 2019, Elon Musk unveiled the first iteration of his next-generation vehicle, Starship.

While SpaceX continues to push the limits, this next endeavor might be its most ambitious yet. SpaceX was founded with the intention of one day creating a human colony on Mars, and Elon Musk hopes that Starship and the Super Heavy rocket will be the way to get there.

Starship was built to carry 100 passengers and will serve as the spacecraft to shuttle both people and cargo to Earth’s orbit and beyond.

Starship has its six Raptors, but the real power behind this transportation system comes from the Super Heavy rocket, which has thirty-seven Raptor engines.

In its final form, the Starship and Super Heavy combination will result in the world’s most powerful launch vehicle ever developed. And SpaceX is working fast to bring this super project to life.

Find out more about SpaceX’s latest space transportation and exploration endeavor on this episode of Countdown to Launch.

Starship

“SpaceX’s Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond.”

Starship and Super Heavy: SpaceX’s Mars-Colonizing Transportation System

“Starship and Super Heavy are the biggest, most important pieces of Elon Musk’s grand plan for SpaceX, his private spaceflight company.”

Elon Musk Sets Out SpaceX Starship’s Ambitious Launch Timeline

“As Elon Musk, the founder and chief executive of SpaceX, says repeatedly, he created a rocket company because he wanted to colonize Mars.”

What is Space Time and how it works? – Black Holes and Our Solar System Documentary

Space-time is a mathematical model that joins space and time into a single idea called a continuum. This four-dimensional continuum is known as Minkowski space. Combining these two ideas helped cosmology to understand how the universe works on the big level (e.g. galaxies) and small level (e.g. atoms).

How Did the Universe Begin Documentary – A Journey Through the Milky Way Galaxy

Our home galaxy, the Milky Way, is believed to be a typical barred-spiral galaxy, composed of the stellar disk, gaseous disk, central barred bulge, and dark matter halo. But observations alone cannot determine clearly how our galaxy looks from the outside, or its evolutionary history. This is mainly due to uncertainties in Solar System’s location within the disk itself and difficulties in determining the distances to sources when mapping Galactic structures.
This movie displays the various structures of the simulated Milky Way Galaxy, based on fundamental physical processes such as the gravitational interactions between stars and gas; the dynamics and evolution of the gas; star formation from the gas clouds; and energetic feedback from the stars.
