That's no moon. It's a...hang on, what should we call it? 🤔 Our VLT has revealed evidence for a moon-like object in the CD-35 2722 system. Yet this new ‘exomoon’ detection is challenging cosmic labels! 🔭 🧪 #exoplanets 1/4

This isn't a scene from #StarWars. What you're looking at is the Tarantula Nebula. While those beams come from the lasers installed on the telescopes that comprise our VLTI. But why are we sending lasers into the sky? Find out: www.eso.org/public/images/potw2616a 🔭 🧪 📷 A. Berdeu/ESO

Without them, the ELT simply would not function! We are talking about the ELT's giant Pre-Focal Stations. Currently undergoing final tests, they will guide the light collected by the telescope to the scientific instruments that will analyse it. More: www.youtube.com/watch?v=OWCB... 🔭 🧪

By pure chance, Stefan observed the Sun last Friday with a custom-made telescope. The active region seen here close to the edge of the Sun's disc have now rotated more towards us. A so-called coronal mass ejection coming from this region has caused the ongoing geomagnetic storm. 📹 S. Ströbele/ESO

Whooooaaaa, this is extremely neat! And spectropolarimetry (which is the best, and what we used in my first paper too!) is at its core 💙 In a nutshell: astronomers used the polarization of light to study the shape of a supernova explosion before it interacted with surrounding material. 🔭🧪

For the first time ever, astronomers have unveiled the shape of a supernova explosion just a day after detection, as the blast was breaking through the star’s surface. Achieved by our VLT, this feat will help us understand how massive stars die: www.eso.org/public/news/eso2520 🔭 🧪 ☄️

If you're mad and find yourself yelling that you want someone launched into the Sun, take a moment, calm yourself, and remember that it takes a lot less Delta v to launch them out of the Solar System instead. You can be mad, but that's no excuse to be inefficient with propellant.
