See the dark spots on the Sun’s surface? In these huge areas, easily the size of a planet, the temperature is lower than on the rest of the Sun’s surface. They can last anywhere from a few days to a few months. The amount of sunspots depends on solar activity, increasing and decreasing in a cycle of around 11 years. A peak is expected in 2025.
Here, the Sun is lighting up the ELT construction site, almost like a shadow theatre. The steel dome, in which the telescope will be encased to protect it from the harsh desert weather, is steadily taking shape. Compare this view with the snapshot taken last year and you’ll see just how much progress has been made on the cladding of the dome. Once it’s finished, more than 600 giant pieces of thermally insulated aluminium will be covering the structure. And it’s not just its size that is impressive: the upper part of this colossal construction can rotate 360 degrees!
While you can’t see it here, the structure that will hold the ELT’s 39-m mirror is also taking shape at a steadfast pace, as is the mirror itself. The ELT is set to open its gigantic eye for the first time later this decade, and scientists are in for some revolutionary discoveries. We can’t wait!

The VLT is equipped with an adaptive optics facility that corrects atmospheric turbulence, making these images sharper than Hubble’s. The system relies on four lasers to create artificial “stars” high up in the atmosphere, whose twinkling is monitored in real time. The lasers have a wavelength of 589 nanometres, and MUSE has a special filter that blocks the light around that wavelength, as shown in the video, so that the lasers don’t contaminate the scientific data.

A multi-layered cladding is being installed over the dome’s steel skeleton — it will thermally insulate the telescope structure to protect it from the extreme desert environment and help regulate the air temperature. Over the telescope, the stunning night sky shows the Milky Way band and the Magellanic Clouds. Towards the end of the clip, the Moon rises in the east before a new day begins.

#ELT #BiggestEyeOnTheSky
It might look small compared to the ELT’s enormous 39-metre primary mirror, but in reality, it is the largest tip-tilt mirror in the world. It will move 10 times per second without bending. Together with M4 — a flexible and very fast deformable mirror — they will both correct atmospheric turbulence and telescope vibrations, delivering sharp images.

These data were captured with the Multi Unit Spectroscopic Explorer (MUSE) instrument, which decomposes the light from every location within its field of view into a rainbow or spectrum. When pointed at galaxies such as this one, MUSE allows astronomers to analyse the chemical composition and motion of gas and stars at different locations within the galaxy.
