Happy launch anniversary JWST! The telescope launched on December 25, 2021 on an Ariane 5 rocket from the European Spaceport near Kourou, French Guiana. Thanks to the hard work of the people at ESA, JWST had a fantastic start to its trip out to its parking spot 1.5 million km away at L2.

On the second day of Christmas, BepiColombo sent to us This shadowy view  Mercury's north pole 🌑 Discover the full image here 👉 https://www.esa.int/ESA_Multimedia/Images/2025/01/Mercury_s_shadowy_north_pole_revealed_by_M-CAM_1_with_labels 🔭

From a medieval Old English text, remarkable common sense about Zodiac style prediction systems.

🌟 Merry Christmas from a newborn star. Earlier this year the NASA/ESA/CSA #Webb Space Telescope took this stunning image of HH30, an edge-on protoplanetary disc. 🧪🔭 🔗 esa.int/Science_Exploration/Space_Science/Webb/Webb_investigates_a_dusty_and_dynamic_disc

For the final day, 24, of #ArtAdventCalendar, I present this illustration which I call Exploration of Amalthea. The latter is a very small moon of Jupiter in a very close orbit. Jupiter would fill half the sky seen from here! #SciArt #spaceart #Blender3d

In this image of NGC 2264, Chandra data (red, purple, blue, and white) has been combined with optical data (green and violet) captured by astrophotographer Michael Clow from his telescope in Arizona in November 2024.

This isn’t a scene of holiday lights gone awry—it’s cold dust in two galaxies! #NASAWebb’s mid-infrared observations uniquely capture the dust in exquisite detail. See how the pair looks when visible and UV light are added from Hubble: https://bit.ly/4oxgK0u

#50YearsOfESA #2023 @esa.int's Jupiter Icy Moons Explorer ('Juice') is an interplanetary spacecraft now on its way to Jupiter to study three of its icy moons: Ganymede, Callisto and Europa. Juice was launched on #Ariane5 VA260 on 14 April 2023 🧪🔭 #SpaceHistory @transport.esa.int @science.esa.int

✨This NASA/ESA/CSA #Webb Space Telescope image shows the Westerlund 1 cluster, a group of massive stars located in our galaxy which are nearly as bright as a million Suns each. 🌌🎄🧪🔭 🔗 esa.int/ESA_Multimedia/Images/2024/10/The_exotic_stellar_population_of_Westerlund_1

🔭 🧪 #extragalactic 🧵 1/ Admire this captivating image of the spectacular spiral galaxy NGC 300, located approximately 6 Mly away in Sculptor. What is striking about the image is the extraordinary abundance of stars that can be seen. Image source➡️ apod.nasa.gov/apod/ap24120...

🧵 Westerlund 2 looks just like a holiday scene in this new, magical image from the JWST. Those red and orange gas clouds and thousands of bright stars recall the #Christmas vibe. ➡️ esawebb.org/images/potm2... 🔭 🧪 #Webb #Universe #galactic #JWST 1/6

This cosmic butterfly is IRAS 23077+6707, the largest planet-forming disc seen around a young star yet!  Hubble has revealed it to be an unusually chaotic specimen, with wisps of material flying far beyond the disc 👉 https://esahubble.org/images/opo2606/ 🔭

💥 A “planet” near the star Fomalhaut just vanished — because it was never a planet. New Hubble observations show it’s debris from massive asteroid collisions. Astronomers now think these crashes are far more common than expected. www.newscientist.com... #Astronomy #Hubble #Asteroids #Fomalhaut

The first data from NASA's SPHEREx mission are out! Check out this video, showing the entire sky in infrared light. The Milky Way runs as a band across the center. Each frame shows a different infrared wavelength, with light from stars, hot gas, and cosmic dust. 🔭🧪 www.jpl.nasa.gov/news/nasas-s...

A red giant star orbiting a black hole 33 times the mass of our Sun... why? ... HOW? In my most recent paper, we try to answer this question using chemistry. Follow along on a Detailed Chemical Analysis of the Red Giant Orbiting Gaia BH3: From Lithium to Thorium➡️ iopscience.iop.org/article/10.3...

One of the most interesting research work I have seen lately. Here is the preprint URL: arxiv.org/abs/2512.14458

Hi friends, please help me spread the word on the open professor position in #planetaryScience we have in Bern 🔽

🔭 Until now, observing the inner regions of the Sun’s enigmatic atmosphere – the corona – was close to impossible. 🛰️🛰️☀️ The satellite duo making up @esa.int’s Proba-3 mission fills this observation gap by creating artificial solar eclipses in orbit 👉 www.esa.int/Enabling_Sup...

Hello everyone! Below are several astrophysics themed FREE conferences-workshop in the coming months you can send abstract (I keep surveying them and will share as I find):

Sometimes when I'm quickly checking whether someone in my team has classified a #RadioAstronomy source correctly, I paste the coordinates into the Aladin Sky Atlas , and confirm... Yes, it is a star! Such a great #AstroSci tool :) (aladin.cds.unistra.fr)

Here is the webpage for Science Ascend journal archive: fire-ae.org/ascend.html As can be seen from the 11th issue, the format changed a lot. Now it is biannual, and January 2026 issue is heavily under work! If you think you can contribute something beneficial for astrophysics community, contact!✍️

The @herts.ac.uk astronomy MSc and PhD applications are open. I'm offering PhD projects on JWST spectroscopy of young stars in Tr 14 and star-cluster formation. I'm also offering an MSc project on variability of YSOs. www.herts.ac.uk/research/cen... #galactic #stellarastro #astro #Physics

For those interested, the slides of the lecture I gave on Stellar rotation and activity at the Evry Schatzman school last September are available on Zenodo ! zenodo.org/records/1784... ☄️ #stellarastrononomy
