Comparison of images with and without Adaptive Optics
Adaptive optics control the surfaces of a telescope’s optic – often the main mirror – to take into account the turbulence in the Earth’s atmosphere. By doing this, the distortion caused by the “twinkling” we can even see when we look at stars with our eyes alone can be removed. This image shows a comparison…

ESOblog: Twinkle, twinkle little star, but not on our watch
ESOblog: Twinkle, twinkle little star, but not on our watch Great blog article from the ESO on adaptive optics – mechanical systems to deform the shape of a mirror to take into account disturbances in the Earth’s atmosphere. The same sort of disturbances that cause stars to “twinkle”. Astronomers have turned to a method…

James Webb Space Telescope Post-Launch Deployment Timeline
1ST HOUR: Starting at liftoff, the Ariane rocket will provide thrust for a little over 8 minutes. Webb will separate from the Ariane V launch vehicle a half hour after launch and we will deploy the solar array immediately afterward. We will also release several systems that were locked for launch. 1ST DAY: Two hours…
