Lasers Help Large Chile Telescope Provide Better Stellar Images

 at first glance, this image looks both awesome and intimidating, with the enormous beams of light resembling some terrible cosmic weapon fortunately, that is not the case this eso picture of the week shows something far more benign — a mixture of gas, dust, and powerful lasers among the largest nebulae in the southern night sky, the carina nebula is a perfect viewing target for eso’s very large telescope vlt in this image, the nebula appears as a stunning pink cloud in the clear sky above eso’s paranal observatory in chile, home of the vlt the carina nebula is a vast cloud of dust and gas — this gas is ionised and made to glow by the stars within the nebula itself  the cutting edge adaptive optics facility installed on one of the 82 metre unit telescopes uts of the vlt is in full operation here the orange laser beams are sent from the uts into the atmosphere where they excite sodium particles, causing them to glow this creates artificial ‘stars’ that can be used to measure the blurring effects caused by earth’s atmosphere, which are then corrected by the telescope

Image issued by the European Southern Observatory, which graphically illustrates the use of lasers to provide a clearer image of the Carina Nebula, one of the brightest nebulae in the night sky.

Reporting for SpaceWatchtower

Powerful lasers are helping the Very Large Telescope Array (VLT) at the European Southern Observatory (ESO) in Chile provide crisper images of the night sky. The lasers aid computers in mitigating normal distortion of Earth's atmosphere.

Located in the Atacama Desert in northern Chile, the VLT is one of the world's most advanced telescopes. It consists of four Unit Telescopes, each with 27-foot / 8.2-meter mirrors, which can change configuration to adapt to turbulence in the Earth's atmosphere.

Atmospheric turbulence has always been a major problem of ground-based telescopes. This turbulence, which causes stars to twinkle, often blurs observations of far away stars, nebulae, and galaxies.

Lasers now aid in the resolution of this turbulence problem. High-tech adaptive optics, attached to the VLT, point and fire powerful lasers toward a target area of the sky astronomers wish to observe. Although a small amount of this laser light may some day reach the star, nebula, or galaxy being observed (at the speed of light, for most celestial objects this would take quite a long time), the laser is not meant to go further than our atmosphere.

Sodium particles in Earth's upper atmosphere are excited by the laser beams. These sodium particles then glow as artificial "stars."

The glowing particles are then used as reference “stars” by VLT computers, to measure the distortion of that particular part of Earth's atmosphere. The computers can then adapt telescope optics to receive telescopic images almost as clear as images from a space telescope.

This laser technology has allowed the VLT to claim several astronomical firsts ---

> First image of a planet outside of our Solar System.

> First to track individual stars around the super-massive black hole at the center of our Milky Way Galaxy.

> First to observe the dim glow of the farthest known Gamma Ray Burst.

  3. This is very helpful with no side effect...Before I began Doctor Aziba natural penis enlargement Product I measured 4 Inches in erect length, and 3 inches in erect girth. While flaccid I measured 3.4 Inches long. I began using his product, slightly skeptical I admit, and just 2 weeks later I was very happy with my progress. I measured 7.5 inches erect length and 6.5 inches erect girth, and 5.5 inches flaccid length. I was actually quite shocked at the huge gains I’d had, and continued using the product regularly, sticking to the usage schedule rigorously. After about 2-3 weeks I am 8.2 Inches in erect length and 8.1 Inches in erect girth. I am also 7.2 inches long while flaccid. This has had a huge impact on my life, not only has my sex life improved greatly, I feel much more confident and proud.
