Galaxy clusters like Abell 2744 can act as a natural cosmic lens, magnifying light from more distant, background objects through gravity. NASA's James Webb Space Telescope may be able to detect light from the first stars in the universe if they are gravitationally lensed by such clusters. (astronomy, space exploration, galaxies)

Article History

Aquitanian Stage, earliest and lowermost division of Miocene rocks, representing all rocks deposited worldwide during the Aquitanian Age (23 million to 20.4 million years ago) of the Neogene Period (23 million to 2.6 million years ago). The stage is named for exposures in the region of Aquitaine in southwestern France.

The Global Stratotype Section and Point (GSSP) defining the lower boundary of this stage, ratified by the International Commission on Stratigraphy (ICS) in 1996, is located in the Lemme-Carrosio Section within the village of Carrosio, Italy. This lower boundary closely coincides with the base of the zone of the foraminiferan (pseudopod-using unicellular organism protected by a test or shell) Paragloborotalia kugleri and the first occurrence of the calcareous nannofossil (remains of ocean-dwelling golden-brown algae) Sphenolithus capricornutus. The Aquitanian Stage underlies the Burdigalian Stage and overlies the Chattian Stage of the Paleogene System.
