Using NASA's Chandra spacecraft, astronomers have performed detailed X-ray observations of a complex galaxy cluster known as Abell 119. Results of the observational campaign, published August 9 on the pre-print server arXiv, shed more light on the properties and nature of this cluster.

Using NASA's Chandra spacecraft, astronomers have performed detailed X-ray observations of a complex galaxy cluster known as Abell 119. Results of the observational campaign, published August 9 on the pre-print serverGalaxy clusters contain up to thousands of galaxies bound together by gravity. They are the largest known gravitationally bound structures in the universe, and could serve as excellent laboratories for studying galaxy evolution and cosmology.
At a redshift of 0.044, Abell 119 is a large galaxy cluster containing about 70 member galaxies. It hosts two narrow-angle tail radio sources and its brightest cluster galaxy is UGC 579. Previous observations have found that Abell 119 is a dynamically complex cluster with multiple substructures.led by Courtney B. Watson of Boston University decided to investigate Abell 119 with Chandra in order to get more insights into its properties.

The evolution of complex grammars: New study measures grammatical complexity of 1,314 languagesLanguages around the world differ greatly in how many grammatical distinctions they make. This variation is observable even between closely related languages. The speakers of Swedish, Danish, and Norwegian, for example, use the same word hunden, meaning 'the dog,' to communicate that the dog is in the house or that someone found the dog or gave food to the dog. In Icelandic, on the other hand, three different word forms would be used in these situations, corresponding to the nominative, accusative, and dative case respectively: hundurinn, hundinn, and hundinum.
