Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. [1] The technique grew out of the multiplane camera technique used in traditional animation [ 2 ] since the 1930s.
This is a list of the nearest supergiant stars to Earth, located at a distance of up to 1,100 light-years (340 parsecs) from Earth. Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list.
Reiniger had long experimented with Chinese shadow puppetry and its methods of suggesting depth by layering shallow, flat planes with colorful backgrounds and backlit action. Her novel design, dating to 1923, used multiple layers of glass to create added depth in the figure-ground relationships, and her camera was at a fixed position above the ...
A recent analysis of the Wilkinson Microwave Anisotropy Probe (WMAP) in 2007 has found an irregularity of the temperature fluctuation of the cosmic microwave background within the vicinity of the constellation Eridanus with analysis found to be 70 microkelvins cooler than the average CMB temperature. One speculation is that a void could cause ...

This number is wrong; originally announced in 1891, the figure was corrected in 1910 to 40 ly (60 mas). From 1891 to 1910, it had been thought this was the star with the smallest known parallax, hence the most distant star whose distance was known. Prior to 1891, Arcturus had previously been recorded of having a parallax of 127 mas.
The Spiderweb Galaxy (PGC 2826829, MRC 1138-262) is an irregular galaxy located in the Hydra constellation, with a redshift of 2.156, which is 10.6 billion light years from the Milky Way. [2]
