Charman et al. (1971) asked whether the LF were the result of single cosmic-ray nuclei entering the eye and directly exciting the eyes of the astronauts, as opposed to the result of Cherenkov radiation within the retina. The researchers had observers view a neutron beam, composed of either 3 or 14 MeV monoenergetic neutrons, in several ...
The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
Astronauts on board the International Space Station are treated to stunning views of Earth on a near daily basis, but a 'red sprite' could impress even the most jaded space traveler. The spectacle ...

Stations have different depths not shown by silhouettes. A space station (or orbital station) is a spacecraft which remains in orbit and hosts humans for
NASA telescopes have captured two ghastly galaxies that look like a creepy pair of staring “blood-soaked” eyes floating in space.. The spiral galaxies, which are located 114 million light ...
Most often space stations have been research stations, but they have also served military or commercial uses, such as hosting space tourists. Space stations have been hosting the only continuous presence of humans in space. The first space station was Salyut 1 (1971), hosting the first crew, of the ill-fated Soyuz 11.
Space tourism was halted in 2011 when the Space Shuttle was retired and the station's crew size was reduced to six, as the partners relied on Russian transport seats for access to the station. Soyuz flight schedules increased after 2013, allowing five Soyuz flights (15 seats) with only two expeditions (12 seats) required. [ 256 ]
Grey eyes make up about 3 percent of the world's population—the second rarest eye color. There are also rare cases of violet and red-colored eyes. What Determines Eye Color?
