The sky appears blue because light passing through Earth’s atmosphere gets scattered and dispersed into space, most dramatically when directly overhead by the Sun. Light rays that have shorter wavelengths like blue and violet are deflected in different directions by minute air molecules, while when longer wavelengths such as red, orange and yellow reach the…
NASA’s Messenger mission ended in 2015 and ESA-JAXA BepiColombo won’t reach Mercury until 2025. These two spacecraft will coordinate measurements of solar wind, radiation and interplanetary dust; providing in-depth knowledge about Mercury’s magnetosphere and exosphere. Mercury’s thin exosphere Mercury lacks an atmosphere to protect it, leaving it exposed to the Sun’s constant solar wind. This…
Sky blue color results from air molecules scattering light. Short wavelengths like blues bounce around more, while longer ones such as red can just wiggle through more freely. Rayleigh scattering was first developed by Lord Rayleigh in 1871. The Sun One major contributor to why the sky appears blue is due to sunlight hitting Earth’s…
In 1961, President Kennedy challenged America to put boots on the moon as part of a geopolitical prestige project meant to outwit Soviet Russia in the Space Race. This program eventually evolved into the Apollo program which eventually succeeded in fulfilling that objective. But the expensive program soon became a political liability as mechanical issues…
Many people incorrectly assume that the sky and water appear blue because of reflection; this is not actually true; their hue comes from something called Rayleigh scattering. As sunlight passes through Earth’s atmosphere it is scattered by gases such as oxygen and nitrogen, with shorter wavelengths (blues) more easily scattered than longer ones (reds). This…
Skyblue is an NEET who enjoys drinking excessive quantities of Pepsi. She also has an unusually large belly. Chikiababy1 designed this character and her subsequent mod as an indirect response to NuSky, her canonical version. Answer: Rayleigh scattering explains why the sky is blue. As sunlight hits Earth and hits molecules in its atmosphere, its…
As sunlight enters our atmosphere, its light is scattered by all of the gases and particles present. Light with blue wavelengths tends to scatter more readily than any other color – giving the sky its characteristically blue appearance during daylight hours. As the sun passes lower in the sky and interacts with various types of…
The sky is an ever-present presence that hosts natural phenomena such as clouds and rainbows, as well as birds, insects, aircraft and kites – not forgetting human creations like aircraft and kites! Additionally, its effects can also be felt through pollution such as smog or light pollution. Pakistanis refer to color as rang (rng). Different…
Director Todd Douglas Miller employs an incredible archive of footage to transport us back 50 years. It serves as an ode to America’s ambition and serves as a reminder of what can be accomplished when we set our sights high. He accomplishes this without narration, instead allowing the astronauts and their crew to communicate directly…
