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

#ARTEMIS II point of view for the next few hours as they go on their close by of the moon. Time in CEST (Europe/Berlin). Earth set at 00:40 and earth rise at 01:20 Sun eclipse at 02:30 (07.04.26) 🔭🧪

There is a full universe behind that wonderful new Artemis II "Night Marble" view of Earth. Here's a breakdown of the stars (and one planet) in the field of view. Look at us! Just a planet hanging out in space. Annotation by Rodrigo González Peinado. 🧪🔭

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

#Aurora over Europe! We're currently experiencing a strong geomagnetic storm, which caused a stunning auroral display all over Europe last night. This time-lapse was captured by our colleague Stefan Ströbele over our headquarters in Garching near Munich. 🔭 🧪 📹 S. Ströbele/ESO

In a few hours in some areas of the world, interstellar visitor 3I/Atlas is going to be occluded by the moon. Interesting unique (and challenging) shooting opportunity, astrophotographers out there? 🔭🧪

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: https://www.eso.org/public/news/eso2520/ 🔭 🧪 ☄️

Our VLT has found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair 😲 Discover more: www.eso.org/public/news/... 🔭 🧪 ☄️ Illustration by ESO/L. Calçada
