Halite crystal moulds have been found locally. [4], The Gai-As Formation is the most widespread depositional unit within the Huab Basin. [5], The basal beds grade into a 20 metres (66 ft) thick succession of silty to fine-grained, and eventually medium- to coarse grained, sandstone. A minor anomaly​—“a stray light problem”— was detected shortly after launch that might degrade the quality of some of the results, especially for the faintest stars, but ESA scientists are confident they can compensate for the problem. Gaia: Introduction to The Earth System. The Gai-As Formation is named after the ruins of a colonial German police station located at a spring in the central Huab area. In August 2015, Gaia completed its first year of science observations, during which it recorded 272 billion positional or astrometric measurements, 54.4 billion photometric data points, and 5.4 billion spectra. [7], The following fossils have been reported from the formation:[4][8][9], The lower part of the formation is correlated with the Serra Alta Formation and the upper part with the Teresina Formation of the Paraná and Pelotas Basins in Rio Grande do Sul, Brazil. This galaxy is intriguing, as over time it has hosted four different observed supernovae. Users should note that no observation can be guaranteed as many reasons may lead to situations in which the data for an object at a predicted time will not be available.

Alcheringa, A. 1039), Gaia is attempting to create the largest, most-precise 3-D map of our galaxy, the Milky Way​. The remarkably high content of analcime (30 volume percent) in some layers may be indicative of contemporaneous volcanic activity. [11] In the Karoo Basin of southern Namibia and the Eastern, Northern and Western Cape, South Africa, the formation is time-equivalent with the Collingham, Ripon and Fort Brown Formations. Fossiliferous stratiform carbonates (10 to 15 centimetres (3.9 to 5.9 in) thick) with molluscs of the Terraia altissima type are transitional to the sand-flat facies which is characterised by sandy, flat and lenticular deposits and occasionally contain abundant root marks. GAIA was founded and is managed by leading investment, engineering and strategy experts. In its observation mode, Gaia spins once every six hours, sweeping its two telescopes across the entire sky and focusing the light it gathers onto a single digital camera. The basal beds of the formation are ubiquitously Beyond Earth: A Chronicle of Deep Space Exploration, 1958-2016. The Gai-As Formation is correlated with a series of formations in the Pelotas and Paraná Basins in southeastern Brazil, deposited in a larger basinal area, 150 million years before the break-up of Pangea. In the lower half of this mainly pelitic succession, intercalations of dark brown, very often concretionary calcareous layers up to 1 metre (3.3 ft) thick, occur. Robert Crane .

Si vous connaissez déjà vos identifiants de connexion, saisissez-les et connectez-vous. [1] The formation is a lithological unit with an approximate maximum thickness of 70 metres (230 ft), deposited in the Huab Basin where it overlies the Huab Formation, separated by a significant hiatus,[2] and is unconformably overlain by the Etjo Sandstone,[3] while later authors assign a separate formation to the upper 35 metres (115 ft) of the Gai-As Formation, named Doros Formation. Amanda Barnett [10] Due to increased subsidence in the central Paraná Basin, thicknesses of the correlative units are considerably greater than that of the Gai-As Formation, attaining a maximum of 1,200 metres (3,900 ft). In September 2014, ESA announced that Gaia had discovered its first supernova, Gaia14aaa, some 500 million light-years from Earth. When the Gaia-Movement Living Earth Green World Action USA, Inc. was incorporated in 1999 we chose this name, because we believed and still believe that the Gaia theory is correct. Launched by a Russian Soyuz rocket, the Fregat upper stage pushed Gaia into a 109 × 109-mile (175 × 175-kilometer) Earth orbit, and then fired again for a long burn into a 214 × 598,200-mile (344 × 962,690-kilometer) orbit at a 15-degree inclination.
