They help fight climate change.
They provide positioning and timing information.
They strengthen our connectivity capacity and resilience.
They are the EU satellite constellations!
Thanks to Copernicus, Galileo, and IRISS, we are enhancing our security and becoming stronger to tackle current and future challenges.

In the EU, we stand against discrimination.
On International Roma Day, we celebrate their diversity, language, art, and culture.
Though improvements have been made, Roma still face marginalization and discrimination.
This year, we are working with the Council of Europe on the EQUIROM project to combat stereotypes and promote Roma achievements.
Every individual deserves respect, and we are committed to turning this vision into reality for all in a #UnionOfEquality.
If you're into astronomy, this is just so wild - a black hole ejected from a galaxy created a 200,000 light-year long trail (larger than our own galaxy) of new stars. https://hubblesite.org/contents/news-releases/2023/news-2023-010
Gender bias can be handed down intergenerationally. Researchers looked at teeth at 139 European archeological sites to see if men were healthier than women. In areas where there was a gendered health gap in Medieval times, the authors found evidence of gender bias today. In PNAS: https://www.pnas.org/doi/10.1073/pnas.2213266120
Two-thirds of the oceans are beyond the jurisdiction of any country.
The species and resources therein risk being overexploited and damaged by climate change and pollution.
We, therefore, welcome the breakthrough agreement on the 🇺🇳 UN High Seas Treaty reached last Saturday. A success we helped achieve.
The treaty will protect the ocean, tackle environmental degradation, fight climate change, and prevent biodiversity loss.
This is a historic moment for our Oceans 💙
We are amid a geomagnetic storm caused by the first of two Earth-directed CMEs. Last night, the aurora was visible as far south as Oregon and Pennsylvania! It will likely continue the next two nights, so if you live in the northern US, Canada, or northern Europe, check the night skies tonight and tomorrow night! I have more info, with photos from last night and info on photographing the northern lights in my article here: https://www.lwpetersen.com/photo-blog/aurora-borealis-february-26-2023/
Turns out the existence of an "alpha" wolf is a myth.
It was based on old/bad experiments, conducted when unrelated wolves were thrown together in captivity.
In actual wild wolves, packs are just families. There's no dominant alpha battling for the top spot -- and in the rare cases there is, it's an alpha *female* wolf.
Insert obvious implications for the use of this term in human societies.

🤩Excited to share our latest preprint on #LaserAssisted Two-Step Glass Wafer Metallization! A simple & efficient solution for improved compatibility between glass & metallic films. #MaterialsScience
➡️ https://dx.doi.org/10.2139/ssrn.4343362
Our team at #Matfyz Charles University, #HiLASE Centre & #CVUT have collaborated to bring this innovation to life using laser microstructuring at ambient conditions. The result is a thick layer of the metal film with high adhesion strength & low surface roughness.
This method offers a solution for those working on #QuantumTech hardware, as it presents a new alternative to chemical-based copper plating. The procedure is simple and efficient and leads to well-defined grains and grain boundaries in the metal film. #Sputtering
The magnetron-sputtered coating in our preprint did not show delamination from the glass substrate, even at a critical load of 60 N. This demonstrates the strong adhesion of the metal film to the glass substrate, thanks to the unique surface structure created by the laser. #SurfaceEngineering
This method of glass metallization will be a game-changer for those in the field of high-frequency electronic devices. The preprint outlines a practical solution for the realization of glass-based circuit materials, offering a more cost-effective alternative to chemical-based copper plating.
We are looking for a PhD student to build a strontium clock at the MPQ in Garching/Germany.
Such clocks may soon become the basis for the official definition of time, and we have a few ideas on how to improve them.

Hello everyone, it's time we start officially posting on Mastodon, so here is our #Introduction -- we are the #Chandra Director's Office, responsible for updating you on all of the goings-on at the #ChandraXray Center operating NASA's Chandra X-ray Observatory. From newsletters and workshops to proposals and peer review, we are here to keep you in the loop with what is going on in Cambridge and in orbit. #Astrodon #Astronomy #Astrophysics #Space #Science #Satellite #NASA #XRaysAreTheBestRays
The second most difficult challenge in science is to have a new important idea; the most difficult one is to convince your colleagues that it is interesting.
Update More in post. The US contains 26 state names are based in American Indian languages
Alabama Alabama is the name of an Indian tribe native to the state. This tribal name may have come from the word albina, which means "campsite" in their own language, or from the words alba amo, which mean "clearing brush."
