The Blue Marble is a photograph of Earth taken on December 7, 1972, from a distance of around 29,400 km (18,300 mi) from Earth's surface. [1]The original image (NASA designation AS17-148-22727) was taken by either Ron Evans or Harrison Schmitt of the crew of the Apollo 17 spacecraft on its way to the Moon, and showed Earth with the South Pole facing upwards; since then, a cropped and rotated ...
The Kordylewski clouds are located near the L 4 and L 5 Lagrange points of the Earth–Moon system. They are about 6 degrees in angular diameter. The clouds can drift up to 6 to 10 degrees from those points. Other observations suggest they move around the Lagrange points in ellipses of about 6 by 2 degrees.
The list of cloud types groups all genera as high (cirro-, cirrus), middle (alto-), multi-level (nimbo-, cumulo-, cumulus), and low (strato-, stratus). These groupings are determined by the altitude level or levels in the troposphere at which each of the various cloud types is normally found. Small cumulus are commonly grouped with the low ...
65 mi (105 km) Components. Serial no. 13. The V-2 No. 13 [1] was a modified V-2 rocket that became the first object to take a photograph of the Earth from outer space. [2] [3] Launched on 24 October 1946, [4] at the White Sands Missile Range in White Sands, New Mexico, the rocket reached a maximum altitude of 65 mi (105 km). [1] [5]
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans ), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes ), all retained by Earth's gravity.
The average cloud cover of the Earth, 2005-2013. Colors range from blue (no clouds) to white (totally cloudy). [6] (click for more detail) Cloud cover values only vary by 3% from year to year averages, whereas the local, day to day variability in cloud amount typically rises to 30% over the globe. Most data sets agree on the fact that the land ...
Lake Michigan set records at about 4°C (7°F) above normal. The other three Great Lakes – Huron, Erie, and Ontario -- were above normal temperatures, though no records were set.The image was gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite at 1:30 p.m. Central Daylight Time (18:30 UTC) on ...
The Oort cloud ( / ɔːrt, ʊərt / ), [1] sometimes called the Öpik–Oort cloud, [2] is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years ). [3] [note 1] [4] The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose ...
