Best and More about 4k Resolution

                               4k Resolution

4k resolution, which is also called as 4k, refers to a horizontal display resolution of 4,000 pixels. Digital television and digital cinematography both use several different resolutions of 4k. In television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard. In the movie projection industry, 4096 × 2160 (DCI 4K) is the dominant 4K standard. the 4k television share market has increased rapidly.  By 2020, more than half of U.S. households are expected to have 4K-capable TVs,[3] a much faster adoption rate than that of Full HD (1080p). 

History:-
The first commercially available 4K camera for cinematographic purposes was the Dalsa Origin, released in 2003. After that 4k technology was developed by many research group in universities, such as University of California, San Diego, CALIT2, etc. YouTube began supporting 4K for video uploads in 2010 as a result of leading manufacturers producing 4K cameras. In November 2013, YouTube began to use the VP9 video compression standard, saying that it was more suitable for 4K than High-Efficiency Video Coding (HEVC). Google, which owns YouTube, developed VP9. Theaters began projecting movies at 4K resolution in 2011. The first 4K home theater projector was released by Sony in 2012. Sony was offering 4K projectors as early as 2004. Sony is one of the leading studios promoting UHDTV content, as of 2013 offering a little over 70 movie and television titles via digital download to a specialized player that stores and decodes the video. 

In 2014, Netflix began streaming House of Cards, Breaking Bad, and "some nature documentaries" at 4K to compatible televisions with an HEVC decoder. Most 4K televisions sold in 2013 did not natively support HEVC, with most major manufacturers announcing support in 2014. Amazon Studios began shooting their full-length original series and new pilots with 4K resolution in 2014. In March 2016 the first players and discs for Ultra HD Blu-ray—a physical optical disc format supporting 4K resolution and HDR at 60 frames per second—were released.

In 2016, Sony and Microsoft released the PlayStation 4 Pro and Xbox One S, respectively, both of which are video game consoles that support 4K streaming, although in most cases the resolution is upscaled to 4K; the Xbox One S also features an Ultra HD Blu-ray disc drive. On November 7, 2017, Microsoft released the Xbox One X, which is capable of native 4K streaming and gaming.

Some Movie Scene In 4k:-

Far Side of Moon

                                                   Far Side of Moon


The far side of the Moon is the hemisphere of the Moon that always faces away from Earth. The far side's terrain is rugged with a multitude of impact craters and relatively few flat lunar maria. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. Both sides of the Moon experience two weeks of sunlight followed by two weeks of the night; the far side is sometimes called the "dark side of the Moon," meaning unseen rather than lacking light.
About 18% of the far side is occasionally visible from Earth due to libration. The remaining 82% remained unobserved until 1959 when it was photographed by the Luna 3 space probe.
 The Apollo 8 astronauts were the first humans to see the far side with the naked eye when they orbited the Moon in 1968.

Research:-

Until the late 1950s, little was known about the far side of the Moon. Liberation's of the Moon periodically allowed limited glimpses of features near the lunar limb on the far side. These features, however, were seen from a low angle, hindering useful observation. (It proved difficult to distinguish a crater from a mountain range.) The remaining 82% of the surface on the far side remained unknown, and its properties were subject to much speculation.

On October 7, 1959, the Soviet probe Luna 3 took the first photographs of the lunar far side, eighteen of them resolvable, covering one-third of the surface invisible from the Earth. The images were analyzed, and the first atlas of the far side of the Moon was published by the USSR Academy of Sciences on November 6, 1960On October 7, 1959, the Soviet probe Luna 3 took the first photographs of the lunar far side, eighteen of them resolvable, covering one-third of the surface invisible from the Earth.

On April 26, 1962, NASA's Ranger 4 space probe became the first spacecraft to impact the far side of the Moon, although it failed to return any scientific data before impact.

UFO sightings:-

Some conspiracy theorists, notably Milton William Cooper, have alleged that some Apollo astronauts had seen UFOs on the far side of the Moon but were told to keep quiet about them.[33][34] Some have allegedly reported seeing an alien base (codenamed "Luna") and even encountered aliens who told them to stay off the Moon. Some photographs circulated on the Internet purport to show a large "castle" on the Moon. The Apollo 20 hoax claims that a manned mission landed on the far side. NASA states that these claims are hoaxes.

Movie scene:-

In Transformers: Dark of The Moon, a Cybertronian spacecraft carrying an invention capable of ending the war between the benevolent Autobots and the malevolent Decepticons, crash lands on the dark side of the Moon.
