Marking 10 Years of Adaptive Optics at the VLT

Facebook X LinkedIn Email
HEIDELBERG, Germany, Nov. 30, 2011 — In November 2001, the NACO instrument — recently added to the European Southern Observatory’s Very Large Telescope (VLT) in northern Chile — captured its first light. Since then, its ability to bring stellar objects into sharp focus via adaptive optics technology has brought about one important scientific discovery after another. This near-infrared image of the active galaxy NGC 1097, obtained with NACO and the Very Large Telescope in 2005, discloses in unprecedented detail a complex network of filaments linking the outer regions with the galaxy’s center. These...Read full article

    adaptive optics
    Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effects of atmospheric distortions. The Earth's atmosphere can cause light passing through it to experience distortions, resulting in image blurring and degradation in various optical applications, such as astronomical observations, laser communications, and imaging systems. Adaptive optics systems actively adjust the optical elements in real-time to compensate for these distortions. Key...
    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
