VISTA: ESO's future telescope

It is expected that the new European telescope of the Southern Hemisphere Astronomical Research (ESO) will be used in early 2009.

Its giant glass has just been installed, the size is 4.1m in diameter, large curvature and short focal length allows wide-range observation. It is ideal for observing low-light objects like galaxies and capturing high-definition images.

VISTA telescope is set at an altitude of 2518m, the installation of equipment is being completed by experts.

Scientific purpose

VISTA will work both in infrared conditions. It will observe the southern hemisphere's regions to study objects that are hard to see in visible light, because they are too cold and surrounded by interplanetary dust clouds. Infrared light is noticeable because they release dust and easily see what's behind the clouds.

VISTA's high-quality images will help to better understand the nature and distribution of the first and galactic generations, and can create a 3D map of the Milky Way and better understand energy. and dark matter

Observation programs conducted simultaneously with other tools are also expected to provide a high level of confidence.

One of VISTA's goals is to determine celestial density in the Redshift ~ 8 Galaxy. Observing early galaxies is a big problem for astronomers today.
