Only 3 days until launch! From #stars to #seas, and from #Earth to the edge of the #universe, #SciX connects #research across disciplines. Discovery has never been this open. Explore with us from Monday 29th September. Get involved at scixplorer.org #ResearchTogether

Using high-resolution JWST observations, a recent study has found a supermassive black hole at the center of an ultracompact dwarf galaxy. 🧪🔭

🔭 What does a centaur in resonance with Uranus tell us about our solar system? In the latest AAS Journal Author Series, Daniel Bamberger (Northolt Branch Observatories) shares insights from his article — and where this research may take planetary science next. 📺 Watch: youtu.be/RDXQzPWouQM

#Research is better when it is connected. In T-minus 4 days, #SciX will bring #EarthScience #EnvironmentalScience and #SpaceScience #researchers closer to the knowledge and tools they need. Get ready for a new way to explore, discover, and collaborate #OpenScience #ResearchImpact

All eyes on comet #3I/ATLAS ☄️ Hubble & Webb have already observed this comet coming from outside our Solar System. Next up, our Mars Express, ExoMars Trace Gas Orbiter and Juice missions will turn their eyes towards it. Learn more 👉 esa.int/3IATLAS 🔭🧪

AAS and 57 other science societies sent a letter to Congress today, expressing concern over provisions in the 7 August 2025 Executive Order titled "Improving Oversight of Federal Grantmaking." aas.org/press/letter... 🔭

We are clear for launch in T-minus 5 days. Science is about to become even more connected. Are you ready for a new dawn of research discovery? #SciX

Neutron stars are born running, and recent research explores just how fast they start off. aasnova.org/2025/09/24/k... 🔭🧪

Timelapse of interstellar comet 3I/ATLAS +background stars in Ophiuchus from 16x1-minute exposures last night (1m Jacobus Kapteyn telescope on La Palma through SARA remote ops). Unlike bound outer solar-system objects, most of its apparent motion is intrinsic, not reflex of Earth orbital motion.🔭☄️

Thank you, @planetarysociety.bsky.social for reminding #Congress of the incalculable value of #NASAScience www.planetary.org/press-releas... #astrophysics #heliophysics #planetaryscience #earthscience #NASA

What’s really at stake if NASA’s science budget gets slashed and entire science missions are canceled? We asked the scientists leading those missions, and their stories reveal what we all stand to lose. Here’s what they told us: www.planetary.org/articles/sci...

For those who celebrate, may you draw strength and vitality from the summer solstice. Sun reaches max declination Jun 21 2025 at 02:42 UT1 (Jun 20 22:42 US EDT) #summersolstice #summer #solstice #calendar #season #timekeeping #Sun #astrophysics 🍎
