ESO 593-8
ESO 593-8, which is known simply as 'The Bird' (also ESO 593-IG 008 or IRAS 19115–212) is group of interacting galaxies located in the constellation of Sagittarius, 650 million light-years away from Earth. It was created by a merger of two spiral galaxies and an irregular dwarf-galaxy. The resulting galaxy has a size similar to the Milky Way: around 100,000 light years. The galaxies were imaged by the Hubble Space Telescope and released in April 2008. The European Southern Observatory has also used the Very Large Telescope to resolve fine details of the galaxy with the use of adaptive optics Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of incoming wavefront distortions by deforming a mirror in order to compensate for the distortion. It is used in astronomical tele .... References Sagittarius (constellation) Spiral galaxies Interacting galaxies {{spiral-galaxy-stub ...

Hubble Interacting Galaxy ESO 593-8 (2008-04-24)
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detailed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
