Earthshine has a calculated maximum apparent magnitude of −3.69 as viewed from Earth. [3] This phenomenon is most visible from Earth at night (or astronomical twilight) a few days before or after the day of new moon, [5] when the lunar phase is a thin crescent. On these nights, the entire lunar disk is both directly and indirectly sunlit, and ...
Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth’s surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks.
Globe at Night is an international scientific research program that crowdsources measurements of light pollution in the night sky. At set time periods within each year, the project asks people to count the number of stars that they can see from their location and report it to the project's website.
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
IllumiNations: Reflections of Earth was a nighttime show performed nightly at Epcot at the Walt Disney World Resort in Bay Lake, Florida.The show utilized fireworks, pyrotechnics, water fountains, fire effects, lasers, searchlights, and a large rotating globe with curved LED screens to create a visual production on the park's World Showcase Lagoon.
[b] Thus, in the Hessdalen lights plasma, the nitrogen ions will decompose (N + 2 + e − → N + N*) more rapidly than oxygen ions. Only ionic species are transported by ion acoustic waves. Therefore, oxygen ions will dominate in the ejected green light balls in Hessdalen lights, presenting a negative band of O + 2 with electronic transition b ...
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
English: View of Korean Peninsula at night from space; note the contrast between North Korea and South Korea in terms of lighting, with the only major point in the North having substantial light being Pyongyang, the nation's capital. Image is derived from a larger composite image of the globe at nighttime compiled by NASA.
