🪐 Installé sur un télescope de l’ESO au Chili, le nouveau spectromètre NIRPS scrute le ciel à la recherche d’exoplanètes dans notre voisinage galactique. Une première salve de publications rend compte de ses performances et confirme la présence d’une 2nde planète autour de Proxima

Welcome, Plato! 🤗

On 1 September, the spacecraft arrived in the Netherlands by boat from Germany via the Rhine River.

In the coming weeks, engineers will add the sunshield & solar arrays and carry out tests to confirm Plato is ready for launch 🚀

🔭 #Exoplanets
A large cargo ship named VAARWEL, painted in blue and white, is sailing through a canal. The ship has a flag at its front and is passing under an open drawbridge in the background. The canal is lined with trees on both sides, and the sky above is bright blue with scattered white clouds. A few people are visible on the bridge and near the water’s edge. In the foreground, at the bottom right, a small boat with a single person inside floats near the ship. A large green truck from Kübler Spedition is transporting a massive container wrapped in a protective tarp. The container displays several logos and text, including the logo of the European Space Agency (ESA), indicating it is part of a specialised transport operation. In the background, there is an industrial building with large metal silos under a blue sky. In a cleanroom environment, two individuals wearing blue lab coats and hairnets are working around a large spacecraft. The spacecraft is covered in protective plastic sheeting and mounted on a white transport platform labelled with technical instructions. In a cleanroom environment, a group of engineers wearing protective coats, gloves, and face masks are working on a large spacecraft component. The component is mounted on a white wheeled platform. The top of the spacecraft carries 26 cylindrical cameras. The workspace is surrounded by structural supports and white fabric walls, creating a clean and controlled environment.

📣 Euclid releases first batch of survey data, including a preview of its very own deep fields!

With just one scan, #ESAEuclid has already spotted 26 million galaxies 👉 www.esa.int/Science_Expl...

Let's explore the treasure trove that our #DarkUniverse detective has uncovered 🧵 1/
🔭🧪 #astrosci
A sea of stars and galaxies sparkle against a black background. Several galaxies can be identified by their elongated shape and/or spiral arms. Some galaxies are seen edge-on while one prominent spiral galaxy at the bottom centre is seen face-on. At the far right, between the middle and top of the image, are some interacting galaxies. Galaxy clusters are also seen, in particular near bottom centre, where features smeared into arcs represent gravitational lensing. The brightest stars in the image have diffraction spikes.

Météo-France exprime sa solidarité avec les chercheuses et chercheurs du monde entier, en particulier aux USA.

Dans un contexte où les effets du changement climatique ne cessent de s'aggraver, la science doit rester notre boussole pour guider nos actions face au défi du siècle.

Ce nouvel obscurantisme, cette purge anti-science : c’est une dystopie.

Today we are very happy to present you KOBE-1, the first planetary system detected by our KOBE experiment. Two small (potentially Neptune-like) planets around a late K-dwarf. Let me give you some insights into this interesting project and new planetary system.

Ce 15 janvier, la dernière donnée en provenance du satellite @esa.int Gaia a été reçue par la Terre. Un nouveau chapitre s'achève pour le cartographe européen, mais au sol, le catalogue d’étoiles continue de s’écrire !

Voici à quoi ressemble Vénus en lumière infrarouge !
theplanetaryguy.bsky.social Paul Byrne @theplanetaryguy.bsky.social · Jan 5
This is what Venus looks like in the infrared.

The lighter colours come from the lower, super-hot atmosphere *glowing* through the cooler, higher cloud layers.
