Ready to travel 75 million light-years?
Our destination is the Kinman Dwarf Galaxy. A few years ago, a star in it disappeared. The end of the video shows an artistic animation of what the star could have looked like before it vanished.

Update on the post below: in a letter sent to Chile's Environmental Assessment Service on 6 February, AES Andes requested the withdrawal of INNA from evaluation.
This formally confirms that INNA is not going ahead.

The Milky Way stretches across the night sky above a dark mountain ridge. An astronomical observatory is silhouetted on the summit.
AES Andes announced that it will step back from the project INNA, planned near our Paranal Observatory.
We welcome this and expect the project to be withdrawn from Chile's Environmental Assessment Service soon, which would formally confirm the cancelation: https://www.eso.org/public/news/eso2602

That's awesome! Absolutely amazing person.
He had some experience and his talks really shows that with some real thought provoking questions and ideas!
This is a really amazing opportunity for astronomy students! 🔭☄️
It's always also very oversubscribed, so make sure to apply to a few things if you want to do a summer research internship

ESO Director General Xavier Barcons (left) and Piero Benvenuti (right), IAU CPS Director, shake hands after signing an agreement. Posters of ESO and the International Astronomy Union’s Centre for the Protection of the Dark and Quiet Sky are visible behind them.
We are continuing to expand our efforts to protect the night skies.
ESO signed an agreement with the IAU's Centre for the Protection of the Dark and Quiet Sky to become a contributing partner.

Here in Gorlitz for #ADASSXXXV. So eerie having such a small contingent of US-based astronomers 🔭🧪
Today we take you to the Tarantula Nebula, but don't worry: no cosmic spiders await us 🕷️
Instead, prepare for a stunning view of this stellar nursery as captured by some of our telescopes. 🔭
A vital tool for our ELT is being assembled.
The Phasing and Diagnostics Station will align the hundreds of segments making up the ELT main mirror, so that they work as a single, unified "phased" surface.

ICYMI, Hayabusa2 touchdown on its target asteroid in 2031 has just become even more challenging.
New observations made with our VLT & other telescopes reveal that the asteroid is much smaller and faster than anticipated.

Remember the first image of the black hole in the M87 galaxy taken by @ehtelescope.bsky.social ?
New analysis shows that some features of the ring around the black hole don't change over the years, but others do!

...he says to Signal's president
A spiral galaxy, showing a thousand different colours that indicate the regions of different stars, gas and dust. The centre of the galaxy has more golden and orange light, while the outer edges fade into a deep blue that further fades into the black of the universe. Speckled across the galaxy are portions of bright pink light, along with patches of brown and black.
Astronomers have created a galactic masterpiece!
Using our VLT, they observed the Sculptor Galaxy in thousands of colours simultaneously 🌈
The more shades of colour there are in an image of a galaxy, the more we can learn about its inner workings.

This image shows a detailed, thousand-colour image of the Sculptor Galaxy captured with the MUSE instrument at ESO’s Very Large Telescope (VLT). Regions of pink light are spread throughout this whole galactic snapshot, which come from ionised hydrogen in star-forming regions. These areas have been overlaid on a map of already formed stars in Sculptor to create the mix of pinks and blues seen here. Credit: ESO/E. Congiu et al.
This is Figure 3 of the "Cosmography of the Local Universe" aforementioned article. It shows two projections of the Local Group and its immediate vicinity. Three concentric blue circles separated by 2 Mpc = 150 km s−1 lie in the supergalactic plane. The top panel is a view normal to the plane and gives the best separation of the principal groups. Solid circles, gray squares, and open triangles identify galaxies, respectively, in, above, and below the plane. The view in the bottom panel is almost edge-on to the supergalactic plane and emphasizes the concentration of galaxies in this plane and the extreme emptiness of a large region above the plane. In the top panel, the NGC 253 galaxy group is encircled, in the direction of the galactic south.
A galactic masterpiece: a stunning image of NGC 253 has just been released by @eso.org. If you're wondering where it is located in our cosmic neighborhood, here it is indicated in a map from our Cosmography of the Local Universe paper.

Image of a screenshot of news headline, saying, "WhatsApp is getting ads using personal data from Instagram and Facebook Forced Consent & Consent Bypass / 16 June 2025 Meta announced today that it also wants to introduce ads on WhatsApp, which will be based on personal data from Facebook and Instagram. This further integrates WhatsApp into other Meta services - an originally independent app, which initially was available for just $1 per year without ads or data usage. This also means that Meta is consolidating its social networking monopoly. EU law was actually supposed to prevent this."
Use Signal. We promise, no AI clutter, and no surveillance ads, whatever the rest of the industry does. <3

Great piece by Govert Schilling on our Extremely Large Telescope!
"It is so large that I have difficulty in perceiving the right scale" he explains, and we can totally relate. 🔭🧪
We have reached the top!
The protective dome of our ELT will have two giant sliding doors that will open at night to allow observations.
Their structure is being installed on the dome, meaning that the ELT has reached its highest point.

Picard management tip: Don't try to go at maximum speed all the time. You'll burn out your engines.
When massive stars die, they go out with a bang 💥
These are supernova explosions and what remains are breathtaking structures like the ones you'll discover in this video 👇
