When @ESAGaia looked back at the Omega Centauri cluster using a special observing mode, it revealed 10 times more stars. 526 587 stars to be precise. Explore Gaia's views of the cluster using this slider 👉 esa.int/Science_Explor…
📢 Our postdoctoral Research Fellowship programme is now open for applications! If you're an early-career scientist or engineer join us to carry out research in a variety of disciplines related to space science, space applications or space technology 👉 cosmos.esa.int/web/space-scie…
Did you know there is cat in Orion? esa.int/ESA_Multimedia… Gaia maps the stars in the sky. Some areas show less stars, because stars are blocked from view by a dense cloud of gas and dust. One of these dark nebula's in the Orion constellation shows a cat! #InternationalCatDay
Today, the #GaiaMission celebrates 10 years of science operations. Over the course of these years, Gaia scanned across 256 billion objects, taking over 3 trillion CCD measurements. Celebrate this milestone with us! Full story on Gaia's celebration: cosmos.esa.int/web/gaia/iow_2…
Our #GaiaDPAC collaborator's project "the virtual starship" is a project that explores the Milky Way and beyond, using #GaiaData and the Milky Way maps created by @Galaxy_map More info 👇🏿
The Virtual Starship has been submitted to the Meta App Lab. If you'd like to be informed about when it is available, please sign-up here: tinyurl.com/vrstarship If you would like to know more, here is a whole video playlist: youtube.com/playlist?list=… Please re-post!
Our @ESAGaia helps astronomers answer important questions about the history of our own galaxy. Just recently, Gaia: 💥 found our galaxy's last major collision to have been surprisingly recent 🪢 discovered two ancient threads of the Milky Way 🌀 revealed that most of our…
☺️Thank you all for your vote for the #GaiaMission! We will do our best to deliver gold with our next data release, ✨#GaiaDR4! Do check out the great work of our competitors in the #ESAGames: Cryosat 👉esa.int/Applications/O… / SMOS 👉 esa.int/Applications/O… / Proba-2…
And the #ESAgames medals continue. Space penthalon bronze for 🥉 #SMOS, silver to 🥈 @esa_cryosat, and gold to @ESAGaia Two more medals for @ESA_EO missions, but alas not the gold. In an unexpected win, the Gaia mission swooped in, because even though it was designed to create…
Here's why @ESAGaia deserves your vote to win the #ESAGames modern space pentathlon 👉 twitter.com/esa/status/181… Our billion star surveyor set out to study stars in our Milky Way, but the Gaia data turned out to be a treasure trove for so many other fields of study. From globular…
Time for the modern space pentathlon at the #ESAGames... Lane 1 - CryoSat covers 🧊 🌊 🚢 🧲 and even 🌋 Lane 2 - Water, vegetation, solar storms. Is there anything SMOS can't do? 🤔 Lane 3 - Gaia, keeping score on 2 billion objects 🤹 Lane 4 - Proba-2's small but does it all!…
Time for modern space pentathlon in the #ESAGames! Our contender is @ESAGaia, up against @esa_cryosat, @SMOS_satellite and #Proba2. Show your support for Gaia with a vote 👉 twitter.com/esa/status/181…

Full thread on Gaia's first neutron star and more 👇
Neutron stars are massive objects formed from the collapse of massive supergiant stars, denser than any other stellar object, except for black holes. Most are detected as radio pulsars, but now #GaiaDR3 also allows to hunt for neutron stars: cosmos.esa.int/web/gaia/iow_2…
💖Great teamwork from our Gaia payload experts of #GaiaDPAC, Gaia teams at @esaoperations and @esa science operations and @AirbusSpace to solve Gaia's first CCD issue in more than 10 years in space! Full story 👇
Space is a dangerous place! Our 'billion-star surveyor' @ESAGaia was recently struck by a high-speed micrometeoroid and the strongest solar storm in 20 years. But thanks to the hard work of the Gaia teams on Earth, routine operations have been restored. esa.int/Enabling_Suppo…
Last week @EAS_meeting was held with a 2-day Gaia symposium: "Gaia: The (TWO) Billion Star Galaxy Census: from the Solar System to our Milky Way and beyond". Interested in the talks of this symposium, slides have been uploaded to the GREAT wiki page here: great.ast.cam.ac.uk/Greatwiki/Grea…
Full thread on the Gaia science result featured this week: cosmos.esa.int/web/gaia/iow_2…👇🏽
Paper day: the dynamical masses across the Hertzsprung-Russell Diagram! This is my favorite plot I have ever made 😍😍 In one sentence, we measure the mass of stars using @ESAGaia wide binaries + Newtonian dynamics + stats + a bit neural network 🥳(1/13) arxiv.org/abs/2308.08584
✨#GaiaDR3's wide binaries allow to derive the dynamical masses of stars. The mean masses for different stellar groups are highlighted in this visual. More details on this stellar weight scale? 👉🏾cosmos.esa.int/web/gaia/iow_2…
