To create the stars used a system of four lasers.
Laser illumination has launched the European southern Observatory, providing a special setting Very Large Telescope, a complex of four optical telescopes located in Chile.
The building shines in the sky four powerful laser beams that illuminate sodium atoms in the upper atmosphere, causing them to glow, forming thus an artificial “star”. Each beam about 30 cm wide, so the lights get very good and stable illumination that it provides, will allow to avoid blur, making the photo have a Very Large Telescope will be even clearer and better.
A system of laser illumination of the sky has recently launched last Tuesday. Thus Very Large Telescope once again confirmed its title of the most modern at the moment telescope in the world. The first of the telescopes of the VLT complex was commissioned in 1998, the rest was built later, in 1999 and 2000. As a single system they started using in 2012, after more than a bundle of tools, the better the image.
To improve the quality of VLT in the mid 2000-ies have been commissioned four auxiliary telescopes. Now their work complements the laser system. Scientists say that the system of laser illumination will necessarily be used in a new large telescope, which will be completed by 2024.
