A star cluster once thought to be part of the spectacular Orion Nebula is actually a separate celestial entity. Scientists using the Canada-France-Hawaii Telescope in Hawaii found that the star cluster NGC 1980 is a distinct, massive bunch of stars in front of the Orion nebula, which at a range of 1,500 light-years is Earth's closest known star factory. The cluster is huddled unevenly around the star iota Ori at the southern tip of the sword in the famed Orion constellation.
At the centre of every large galaxy lives a giant black hole that swallows gas or dust clouds that stray too close. As matter spirals inwards, it is compressed into an accretion disk. By the time it falls into the black hole, the matter is so hot that much of its mass is converted to energy, which emerges as heat, light and jets of high-energy particles. http://www.nature.com/polopoly_fs/7.14928.1389717382!/image/Quasar.jpg_gen/derivatives/landscape_630/Quasar.jpg
The Hubble telescope has captured an image of an unusual edge-on galaxy, revealing remarkable details of its warped dusty disk and showing how colliding galaxies spawn the formation of new generations of stars. The dust and spiral arms of normal spiral galaxies, like our own Milky Way, appear flat when viewed edge-on. This Hubble Heritage image of ESO 510-G13 shows a galaxy that, by contrast, has an unusual twisted disk structure, first seen in ground-based photographs.
Navajo Petroglyphs at Crow Canyon.Detail of pictograph panel, Crow Canyon. Navajo people interpret this as a representation of Gháá' ask'idii. His horns tie him to the Mountain Sheep People, an ancient race associated with the night chant, Tl'eejí. Generally a benevolent figure, Gháá' ask'idii carries many kinds of seeds and foods in his feather-crowned backpack.Photograph by James Matthew Copeland, via New Mexico Bureau of Land Management.
Mira Schendel | Tate Modern, London | 26.09.13 - 19.01.14 | @tate This exhibition, late in 2013, is the first international full-scale survey of "one of Latin America's most important and prolific post-war artists", Mira Schendel. Swiss-born, Brazilian-based Schendel was a primary force in writing the visual idiom of European Modernism in Brazil. Image: Mira Schendel, Untitled (Disks), 1972
What is pictured above is actually a disk galaxy being seen almost perfectly edge on. The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4762, a galaxy in the nearby Virgo Cluster of Galaxies, is so thin that it is actually difficult to determine what type of disk galaxy it is. Its lack of a visible dust lane indicates that it is a low-dust lenticular galaxy, although it is still possible that a view from on top would reveal…
