Here’s a cool 4K video of coloured liquids in space, courtesy of NASA:
Once again, astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

What is 4K resolution?
“4K” resolution refers to a horizontal resolution of approximately 4,000 pixels. The use of width to characterize the overall resolution marks a switch from previous television standards such as 480i and 1080p, which categorize media according to its vertical dimension. Using that same convention, 4K UHD would be named 2160p. The first commercially available 4K camera was by Daisa Origin in 2003, and YouTube began supporting 4K video since 2010, with improved support (VP9 video compression format) since 2013. VP9 format was developed by Google.
