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.

The various observations used here were taken at different times, by different teams and with different facilities, and put together for the purpose of the zoom effect. The images go from visible wavelengths at the beginning to infrared, with the very final image being taken at radio wavelengths.

Each 1.5 metre segment is coated with just 1.7 grams of highly reflective silver, as well as adhesive and protective layers. Precise sensors are installed to detect misalignments on a nanometer scale once the telescope is fully built. Out of the 798 total segments that will be used to form the telescope, two will be recoated every day to ensure every segment maintains the best reflectivity.

Partly built at a nearby base camp, large steel elements arrive at the peak ready to be neatly assembled together into the dome. The steel structure provides the skeleton around which a protective insulated cladding is now being applied. It rests on a concrete foundation separated from the central pier where the telescope will be, to reduce vibrations propagating through the ground. The dome can rotate on 36 trolleys allowing the telescope to observe the whole sky.
A new webcam inside the dome shows progress in the azimuth structure that will support the telescope, as well as the two huge platforms that will hold the ELT’s scientific instruments.
In this timelapse, each frame was captured at the same time every day; the Sun’s apparent position on the sky changes with seasons as the Earth orbits around the Sun. This webcam view provides an incredible peek at the ELT construction progress, and we cannot wait to see the wonders its 39-metre eye will discover.

When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. That seems to be the case of the white dwarf WD 0816-310, the Earth-sized remnant of a star similar to, but somewhat larger than, our Sun.
The scar the team observed is a concentration of metals imprinted on its surface. These metals seem to originate from a planetary fragment as large as or possibly larger than Vesta, which is about 500 kilometres across and the second-largest asteroid in the Solar System.
This video summarises the discovery. For more details, check: eso.org/public/news/eso2403/.

#TourESO
There are over 8,000 satellites in this orbit already — and due to the light they reflect, they hinder the view and exploration of the night sky from the ground.
So, astronomers have taken action to mitigate this threat. For example, ESO and other astronomical organisations have petitioned the UN to safeguard the night sky by advocating for dimmer satellites.
These initiatives have yielded positive results already, with many space companies painting their satellites darker, so that they become less reflective.

#TourESO
We are able to see a few thousands stars from Earth with our very own eyes. However, our capacity is impaired by light pollution and its degree of severity depending on where we are.
If we could limit unnecessary artificial light in cities, we might be able to bring back at least part of the starry night sky we enjoy in remote areas.
As ESO astronomer Suzanna Randall points out, limiting light pollution would be beneficial far beyond the beauty of the stars. It could improve our health and that of animals, as well as reduce waste of energy and money.
Learn more about the issue of light pollution with this episode of #ChasingStarlight : youtube.com/watch?v=Lvw8J4nwpC0

The test moved the dome 10 m in either direction at 1 cm/s, but the final operating speed will be a walking pace of 5 km/h. The test was performed by engineers of Cimolai, the company contracted by ESO to design and build the ELT dome and telescope structure. The humans hard at work in this sped-up video show, for scale, the sheer size of the telescope dome. Rotating the dome is no small feat, as its skeleton currently weighs about 2500 tons, and will eventually weigh around 6100 tons when finished. This first test was carried out “manually” with special hydraulic devices, but eventually the enclosure will rotate via motorised bogies. While the motion of the dome is designed to be smooth, and was found to be during this test, the dome stands separate from the rest of the structure in order to limit vibrations to the telescope itself.
The dome, in its final form, will have an insulated aluminum cladding to protect the telescope from the elements and sliding doors to open it to the stars. Building this marvel of engineering in the middle of the desert presents unique challenges, and yet, recent achievements such as the dome rotating and the first mirror segments stored at Paranal show the ELT is moving closer to becoming reality.

Such systems are known as over-contact binaries, and VFTS 352 is the hottest and largest of them all. 😲
Its mass is around 57 times that of the Sun, and with a surface temperature of about 40,000 degrees Celsius (more than six times hotter than the Sun's surface 🥵), this relationship is certainly steaming!

With the segments at Paranal, the next phase in this intricate process involves the coating of the mirror segments in the ELT Technical Facility to give them their highly reflective finish — a process that will be reiterated on each segment every 18 months once the ELT begins observations.
