With the help of the MUSE tuner installed on the VLT terrestrial telescope and the new adaptive optics system, astronomers captured Neptune and distant stellar clusters. The resulting images are superior to similar images taken by the Hubble Space Telescope. Similar systems are installed on other terrestrial telescopes, which will then allow astronomical object images to be acquired in a visible range of wavelengths with a resolution not inferior to orbital observatories. , and to further explore the properties and evolution.

One of the main problems that limit the resolution of terrestrial telescopes is atmospheric turbulence, which leads to a blur and a deterioration in the quality of astronomical images. Objects To eliminate this problem, one can either take the monitoring tool in the space, or compensate the distortion by means of an adaptive optics. The more the factors take into account such an image correction system (turbulence dependence on the altitude, different contribution of the different layers of the atmosphere to the distortion), the more the details are visible on images received
Very Large Telescope, which is located in Chile and consists of four main telescopes of 8.2 meters and four additional telescopes of 1.8 meters, working in the vast area of the electromagnetic spectrum – from the street In February of this year, the engineers managed to combine the luminous flux of the four main 8.2-meter telescopes and make the VLT the largest optical telescope in the world, with an equivalent aperture of 16 meters

Astronomers now report the results of observations made on one of the major VLT telescopes using the small field and the small MUSE system (Multi -Spectroscopic Explorer Multi-Spectrograph) AOF
As a result of the observations, it was possible to capture the image of Neptune and the NGC 6388 remote cluster, which exceeds the quality of similar images taken by the Hubble Space Telescope. A similar system is already equipped with a HAWK-I receiver operating on another major VLT telescope, and the method of "laser tomography" will be implemented not only on the new VLT receivers but also on the 39-meter European telescope currently in construction. ), which, after its creation, will become the world's largest telescope operating in the optical spectrum and the near infrared
