Synthesis: NASA Data Visualizations in Ultra-HD (4K) Our senses tell us about the natural world, but our senses cannot tell us everything. That’s why we use tools, and NASA develops some of the most sophisticated, most exciting tools of all. Designed to reveal aspects of the Earth, the Sun, The Moon, these tools gather essential data about the world around us, while other instruments peer way out to much more distant places. When these data are turned into visualizations, we discover a complexity and elegance to the natural world that would otherwise elude our physical senses. Even more important, we uncover vital clues to understand how things work, how they’re changing, and what the implications for those changes may mean. With the advent of Ultra-High-Definition video, more commonly known as “4K Video”, those images take on an enhanced majesty and power. In this video, we present images about our home planet, as well as the life-giving star it orbits, and the mysterious moon that travels with us through space.

The Sound (& Visions) of Silence “Sharing the incomparable silent beauty of our planet with all our fellow travellers on this, our Spaceship Earth.” @SergeyISS @Astro_Paolo @Astrokomrade “Our thanks to Mr. Paul Simon and Disturbed.” “Our thanks to all the people within the partnership of the International Space Station who show us daily what heights we can achieve together.” “The Sound of Silence” Written by Paul Simon. SONGS OF UNIVERSAL, INC. on behalf of PAUL SIMON MUSIC. Performed by Disturbed. Courtesy of Warner Bros. Records. Captured by astronauts Sergey Ryazanskiy, Paolo Nespoli, and Commander Randy Bresnik, the video features stunning footage of Earth and outer space from the International Space Station in low-earth orbit during the months of August through October in 2017.

Europe from Space in 4K Got three minutes to spare for a tour of southern Europe? That’s all the time it takes, when you have a 4K camera orbiting Earth 250 miles up—and we do, on the International Space Station. This Ultra High-Definition video was shot in August 2016 as the station travelled nearly 1000 miles, taking in views from above the western coast of France to the Iberian Peninsula, Italy, Switzerland, southern Germany and Austria, and southward to the countries of the Balkan Peninsula. Music by Joakim Karud.

The Sun's surface is primarily composed of hydrogen and helium, and the main gas reaction that occurs there is nuclear fusion. The dominant fusion process in the Sun is known as the "proton-proton chain," and it can be summarized as follows: 1. Proton-Proton Chain (PP Chain): - Step 1: Two hydrogen nuclei (protons) collide and fuse to form a deuterium nucleus (one proton and one neutron), releasing a positron and a neutrino as byproducts. - Step 2: A deuterium nucleus combines with another proton to form helium-3 (two protons and one neutron), releasing a gamma ray. - Step 3: Two helium-3 nuclei collide, and one of them captures two protons to form helium-4 (two protons and two neutrons), while the other helium-3 nucleus is left with only one proton. This releases two protons. Overall Reaction: 4 hydrogen nuclei (protons) -> 1 helium nucleus (helium-4) + energy This continuous process of nuclear fusion in the Sun's core converts hydrogen into helium, releasing an enormous amount of energy in the form of light and heat. This energy is what powers the Sun and provides the heat and light that sustain life on Earth through the process of radiation from the Sun's surface.

The heart touching views of the Moon.
