The picture of the planet Neptune was gotten amid the testing of some new features that were added to the European Southern Observatory’s Very Large Telescope from Chile.
This planet is blue, huge, kind of cold and about 4.3 billion kilometers away. Yet, stargazers utilizing the latest optics innovation have taken a picture of Neptune that is almost as sharp as those taken from the Hubble Space Telescope.
The European Southern Observatory’s Very Large Telescope (or VLT for short), settled in the mountains from the Atacama Desert in Chile, and it was, as of late, furnished with another kind of adaptive optics called laser tomography. Adaptive optics amend pictures for the turbulence of the atmosphere of our planet.
Why can’t they take clear pictures?
Whenever researchers and novice space experts take pictures of planets, stars, cosmic systems, or any other objects from out there, their principal enemy is the atmosphere of our planet. The variation of temperature and the thickness of the air cause turbulence, making it hard to photograph or simply watch with no problems. That is truly why we see the stars that twinkle.
Be that as it may, the new features coming from VLT can change this for us.
Four fantastically brilliant lasers projects line 30 centimeters in diameter into the sky that make a fake guide star for the telescope to center around.
The light of the star is utilized to decide the barometrical turbulence. At that point, the telescope makes 1,000 calculations for each second and changes the state of one of its mirrors, amending for the contortion.
If it gets into the wide-field mode, it can revise for atmospheric air turbulence up to one kilometer over the telescope. In any case, in the narrow-field mode (this one is like like zooming in with your camera), it can amend for all turbulence, and the results represent significantly more honed pictures. This produces pictures almost as clear as those from Hubble, which has no air turbulence to manage on the grounds that it’s above the atmosphere of Earth.
