As you might expect from the space agency, NASA has always been at the forefront of visual technology. In 2017, NASA astronauts Peggy Whitson and Jack Fischer live-streamed a show from the International Space Station using ultra-high-definition 4K technology – the next-generation standard for video – for the first time. .
Using 4K allows for incredibly crisp picture quality, with a horizontal screen resolution of up to 4000 pixels (the horizontal pixel count of the previous 1080P high definition standard was 1920). The ISS’s high-definition 4K camera has the capacity to record up to 300 frames per second – compare that to the 60 frames per second of a high-end smartphone – while the main mirror of the Hubble Telescope, which is what that the telescope uses to capture images from space and send it back to Earth, can collect about 40,000 times more light than the human eye. Using these technologies, along with ultra-high definition equipment on other spacecraft, NASA has continued to capture hours and hours of 4K footage, delivering a compelling video gallery of immersive images, as well as the generation of recreations of past events in high definition renderings. .
While you will obviously only get all the benefits of 4K if you watch such footage on a 4K capable display, the videos still look convincing on standard screens.
Here is a small selection of our favorite videos from the 4K space.
On April 17, 2016, an active region on the sun’s right side emitted a mid-level solar flare. This event was captured by NASA’s Solar Dynamics Observatory, a spacecraft from NASA’s Living With a Star mission that has been observing the sun since 2010. This video is especially special, as the rocket was captured in several lengths of time. extreme ultraviolet light wave, which is generally invisible to our eyes, but is shown in various color-coded sequences in the Solar Dynamics Observatory images for easy viewing. (Each differently shaded montage that you see has been captured in a different light spectrum.) The footage is accompanied by the song named “Collide” by Greg Lehrman.
The astonishing phenomenon of the Northern Lights is something that some of us can only dream of having the chance to see in person. However, thanks to the UHD camera on the International Space Station, we can enjoy one of the best views of the planet from our own homes. This short video uses time-lapse filmed from the International Space Station and shows the Aurora Borealis and Aurora Australis phenomena that occur when electrically charged electrons and protons in Earth’s magnetic field collide with neutral atoms in the upper atmosphere .
This video uses data from the Lunar Reconnaissance Orbiter spacecraft currently orbiting the Moon to recreate some of the breathtaking views the Apollo 13 astronauts saw on their journey around the Farside in 1970. These 4K accelerated visualizations show many different views of the lunar surface, starting with Earthset – the apparent setting of the earth below the lunar horizon – and sunrise and ending with when Apollo 13 reestablished radio contact with Mission Control after the ‘have lost while behind the moon.
The path of the free return path around the Moon is also shown when the spacecraft began to return to Earth. It’s a fascinating glimpse into the wonders that Apollo 13 astronauts saw in real life. Music lovers will also be able to view the special version of the video, staged on “Clair de Lune” by Claude Debussy by the National Symphony Orchestra Pops, created as part of a celebration of NASA’s 60th anniversary.
Photographed in 2015, these then groundbreaking images come from NASA’s Hubble Space Telescope, captured as part of a series of annual portraits of the solar system’s outer planets. The project was created to help current and future scientists see how these giant worlds evolve over the years. At the time, he revealed details never seen before about Jupiter, including a rare wave just north of the planet’s equator and a unique filamentary feature at the heart of the Great Red Spot.
“Share the incomparable silent beauty of our planet with all of our fellow travelers on this Earth spacecraft,” Russian astronaut Sergey Ryazansky said of the video. He captured the footage from this montage alongside fellow ISS residents Paolo Nespoli of Italy and US Commander Randy Bresnik. As part of “The Sound of Silence” by Paul Simon performed by Disturbed, this 4K video presents you with stunning images of Earth from the International Space Station in low Earth orbit during the months of August through October in 2017.
6. Ocean Moon Glint and City Night Lights in 4K UHD
This video includes time-lapse footage taken by NASA astronaut Jack Fischer from the International Space Station in 4K UHD. The video passes over the moon’s reflections in the Pacific Ocean and over the night lights of San Francisco, California, to Denver, Colorado. A lunar glare occurs when light from the moon reflects off the surface of a sea or ocean at an angle and creates a rare glare of light, not something you see every day.
7. Europe from space in 4K
With this offer, NASA gives you the chance to visit southern Europe in just three minutes. Apparently that’s all the time it takes when you have a 4K camera orbiting Earth 250 km away. This ultra-high definition video was shot in August 2016 as the International Space Station traveled nearly 1,000 miles, taking in views from the west coast of France to the Iberian Peninsula, Italy, Switzerland, the south from Germany and Austria, and south to the countries of the Balkan Peninsula.
It’s a fascinating little clip to watch to bring home the magnitude of the Universe. On November 11, 2019 (11/11/19!) NASA’s Solar Dynamics Observatory watched Mercury move across the Sun. What’s fascinating is how little Mercury is depicted against the star. Mercury is the smallest planet in our solar system, measuring around 3,000 miles in diameter, but it looks like a single marble in this video. The clip runs through the variety of wavelengths of light in which the Solar Dynamics Observatory captured the event.
9. A flight through the CANDELS Ultra Deep Survey field [Ultra-HD]
This stunning visualization takes us six billion light-years away to travel the CANDELS Ultra Deep Survey field to show the various galaxies and their three-dimensional distribution, although the distances have been reduced for cinematic purposes. CANDELS is an acronym for the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey project, and it is one of the largest projects ever carried out with the Hubble Space Telescope.
10. NASA’s thermonuclear art – the sun in Ultra-HD (4K)
This absolutely fascinating video gives you around 30 minutes of footage of the sun’s surface. From images from NASA’s Solar Dynamics Observatory, which monitors the star 24/7, these images are captured in 10 different wavelengths, each of which can highlight a different temperature of the solar material. Watch to see streams of particles called solar wind, occasional eruptions of giant clouds of solar matter called coronal mass ejections, and x-ray explosions called solar flares.
11. The Earth: 4K Extended Edition
If you can’t get enough of Earth, this expansive read of ultra-high-definition views of our planet captured by NASA astronaut Jeff Williams during his mission to the International Space Station in 2016 is for you. It offers a full hour of views from the ISS in which you can see the entire planet 400 km away. Williams is a great choice for collecting his favorite images – he has spent more than 530 days living and working on the ISS.
12. 4K video of colored liquid in space
Finally, a fun look inside the ISS itself. Astronauts on the International Space Station dissolved an effervescent tablet into a floating water ball and captured images using a 4K camera. The Epic Dragon camera from RED, a digital cinema company, can capture an incredibly high frame rate and super high quality resolution, producing amazing effects.
