Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions.
1959 – Explorer 6 sends the first image of the entire Earth from space. [178] 1959 – Luna 3 sends the first images of another celestial body, the Moon, from space, including its unseen far side. [179] 1962 – Mariner 2 Venus flyby performs the first closeup observations of another planet. [180]
Fog is commonly considered a surface-based cloud layer. [21] The fog may form at surface level in clear air or it may be the result of a very low stratus cloud subsiding to ground or sea level. Conversely, low stratiform clouds result when advection fog is lifted above surface level during breezy conditions.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
The first television image of Earth from space from the TIROS-1 weather satellite. 1959 – The first weather satellite, Vanguard 2, was launched on February 17. It was designed to measure cloud cover, but a poor axis of rotation kept it from collecting a notable amount of useful data.
The composite image taken from multiple cameras on-board an Aerobee sounding rocket produces the first full view of the earth from space. Unlike the earlier still-frames and motion picture images taken by the V-2 rocket which captured only segments, the Aerobee provided the first panoramic (complete) view of the planet and also provided the ...
