In July 2020, after a 20-year-long survey, astrophysicists of the Sloan Digital Sky Survey published the largest, most detailed 3D map of the universe so far, filled a gap of 11 billion years in its expansion history, and provided data which supports the theory of a flat geometry of the universe and confirms that different regions seem to be ...
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Sky-Map.org (or WikiSky.org) is a wiki and interactive sky map that covers over half a billion known celestial bodies. [1] WikiSky is designed, in part, as a wiki.Users can edit information about different stars by writing articles, adding Internet links, uploading images, or creating a special interest group for a specific task.

ASTER data is used to create detailed maps of surface temperature of land, emissivity, reflectance, and elevation. [1] In April 2008, the SWIR detectors of ASTER began malfunctioning and were publicly declared non-operational by NASA in January 2009. All SWIR data collected after 1 April 2008 has been marked as unusable. [2]
