Typical short-exposure negative image of a binary star (Zeta Boötis in this case) as seen through atmospheric seeing. Each star should appear as a single Airy pattern, but the atmosphere causes the images of the two stars to break up into two patterns of speckles (one pattern above left, the other below right). The speckles are a little ...
The CfA2 Great Wall has the maximum dimensions of either 500 million or 750 million light years depending on the figure and the reference used. [citation needed] It is 200 million light years in width and about 16 million light years in thickness. Its nearest point is about 300 million light years from Earth, while its furthest point is 550 ...
The short exposure images are aligned by using the brightest speckle and averaged to give a single output image. [7] The method involves calculation of the differential shifts of the images. This is easily accomplished in astronomical images since they can be aligned with the stars. Once the images are aligned they are averaged together.
Microgravity has a negative effect on human physiology that causes both muscle atrophy and bone loss. Terminology The use of the short version space , as meaning 'the region beyond Earth's sky', predates the use of full term "outer space", with the earliest recorded use of this meaning in an epic poem by John Milton called Paradise Lost ...
In cosmology, galaxy filaments are the largest known structures in the universe, consisting of walls of galactic superclusters.These massive, thread-like formations can commonly reach 50 to 80 megaparsecs (160 to 260 megalight-years)—with the largest found to date being the Hercules-Corona Borealis Great Wall at around 3 gigaparsecs (9.8 Gly) in length—and form the boundaries between voids ...

[clarification needed] One possible explanation of this concentration is the Hercules–Corona Borealis Great Wall. [8] [9] The wall has a mean size in excess of 2 billion to 3 billion parsecs (6 to 10 billion light-years). [5] Such a supercluster can explain the significant distribution of GRBs because of its tie to star formation.
