Big. The galaxy? Bigger. What's bigger than that? Before you smugly suggest \"The universe?\", check this out: 4K Videos from NASA!A little more than a decade ago, television transformed from the boxy, standard definition dimensions of 20th century engineers to the wider and sharper images of high definition TV. Well into the 21st century now, rapid growth in the next generation of video images promises to deliver spectacular pictures with profoundly greater fidelity and resolution than even the best HDTV. Officially known as Ultra-High Definition Television, it has rapidly come to be known as \"4K\", a moniker derived from the approximate width of images measured in pixels horizontally across a screen.NASA has a long legacy pushing the boundaries of advanced media technologies, befitting its unique role in presenting important, state-of-the-art science and engineering stories to the American public. On this web page you'll find the first major release of 4K video content, presented in the public domain. The release of these media are concurrent with the launch of a new, non-commercial Ultra-High Definition channel in partnership with Harmonic. For each of the following items on this website you may preview the program in your browser or you may select one of several different resolutions from the \"download\" button in the lower right hand corner of each. Be advised that the 4K videos will require fast internet connections and substantial storage space.SYNTHESIS: NASA DATA VISUALIZATIONS IN ULTRA-HD (4K) || ", "release_date": "2015-11-01T08:00:00-05:00", "update_date": "2025-01-06T01:28:02.504137-05:00", "main_image": { "id": 438419, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a012000/a012034/Combined.00_29_05_33.Still002.jpg", "filename": "Combined.00_29_05_33.Still002.jpg", "media_type": "Image", "alt_text": "The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on February 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun's atmosphere, the corona.SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. Different temperatures can, in turn, show specific structures on the sun such as solar flares, which are gigantic explosions of light and x-rays, or coronal loops, which are stream of solar material travelling up and down looping magnetic field lines.Scientists study these images to better understand the complex electromagnetic system causing the constant movement on the sun, which can ultimately have an effect closer to Earth, too. Flares and another type of solar explosion called coronal mass ejections can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy. NASA's Goddard Space Flight Center in Greenbelt, Md. built, operates, and manages the SDO spacecraft for NASA's Science Mission Directorate in Washington, D.C.All tracks are written and produced by Lars Leonhard.Credit: The SDO Team, Genna Duberstein and Scott Wiessinger, Producers", "width": 1920, "height": 1080, "pixels": 2073600 } } ], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
