ESOcast 172 Light: Supersharp Images from New VLT Adaptive Optics (4K UHD)
ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. The combination of exquisite image sharpness and the spectroscopic capabilities of MUSE will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before.
ESOcast is a video podcast series dedicated to bringing you the latest news and research from ESO – Astronomy made on planet Earth. Here we explore the Universe's ultimate frontier with our host Doctor J, a.k.a. Dr. Joe Liske.
The ESOcast is offered for download in several formats: standard (.mov, .mpeg, .mp4, .m4v) and HD (High Definition). HD is rapidly evolving into one of the leading video formats in the video on-demand market. Information on the specs of the available video formats is accessible on the Video Formats Page.
ESOcast HD videos can be watched on TV by the use of digital media receivers such as Apple TV.
Standard Definition (640 x 480)
High Definition (1280 x 720)
