CERN Scientists Study Asteroid Materials with Particle Beams

The Aditya L1, Solar Orbiter and Proba-3 spacecrafts are studying the Sun from different perspectives. ISRO and the European Space Agency (ESA) are jointly organising the ISRO-ESA Helio physics Workshop in Trivandrum, during Jan 19-23, 2026. The workshop has brought together the global experts and researchers from India, Europe and other parts of the world.

🚀 Rocket Lab Reports Tank Failure During Neutron Rocket Tests Rocket Lab confirmed that a Stage-1 tank of its Neutron rocket ruptured during hydrostatic pressure tests. The company says such failures are not unusual during qualification, no major infrastructure was damaged, and a replacement tank is already in production. 💡 Why it matters: ▪️ Highlights how challenging new rocket development is ▪️ Adds uncertainty to Neutron’s first-launch timeline ▪️ Shows Rocket Lab prioritizing test rigor over speed ▪️ Reinforces the cost of getting heavy-lift right ⚙️ What’s happening: Neutron is Rocket Lab’s upcoming medium-lift reusable rocket, targeting its first flight in mid-2026. CEO Peter Beck has stressed that reaching orbit on the first attempt matters more than rushing to launch. 🚀 What’s next: Rocket Lab will analyze the test data and provide an updated schedule in its next earnings call. ⚡ In rocketry, failures on the ground are cheaper than failures in flight. #RocketLab #Space #Neutron #SpaceLaunch #Aerospace #Technology 📸 Neutron Rocket 

Recent observations using the Gemini South telescope have revealed a massive cloud containing vaporized metals orbiting a secondary object in a distant star system. This cloud, which obscured its host star for nearly nine months, provides rare insight into the dynamic processes that can occur in mature planetary systems. Spectroscopic analysis identified winds of gaseous metals, such as iron and calcium, and allowed for the first direct measurement of internal gas motions in such a disk. These findings offer valuable clues about planetary system evolution and the potential for large-scale collisions long after formation.

🌟 Why the Einstein Telescope Goes Underground The Einstein Telescope will be built mostly underground - not by choice, but by necessity. To detect incredibly faint gravitational waves, ET must escape the "noise" of the surface world, including Newtonian noise that can't be shielded against. A new article on the ET page takes you below the surface and explains: 🟦 why ET must go underground 🟦 what the underground facility could look like 🟦 how safety is designed into every step 🟦 what it feels like to work underground — from the people who do it 👉 Read here: https://lnkd.in/dwweVX29 With thanks to the contributors: Dorota Rosinska, Patrick Werneke, Jean-Philippe Tock, Saverio La Mendola, Maria Marsella Einstein Telescope, Einstein Telescope IT, CERN Photo: Andreas Freise

JWST challenges decades-old models and introduces a powerful new technique (interferometry) for studying active galactic nuclei (AGNs) . The dominance of the tore heating over the outflow is clrarly visible. This is possible to see for the first time and change previously thinking model. https://lnkd.in/d2rh6CjC

Russia Revives Plasma Rocket Research That Could Theoretically Reach Mars in 30 Days 🤔 They have unveiled a plasma based rocket engine that could slash Mars travel time from 6–9 months to just 30-60 days. Developed by researchers at Rosatom’s Troitsk Institute, the engine uses electromagnetic fields to accelerate hydrogen plasma, producing continuous thrust rather than short chemical burns. In ground tests, the prototype achieved plasma exhaust velocities of up to 100 km/s, nearly 20× higher than conventional chemical rockets. According to reported data, the engine operates at around 300 kW of power, delivers roughly 6 newtons of thrust, and has demonstrated a working life of about 2,400 hours in a large vacuum chamber simulating space. The concept relies on sustained acceleration over long periods, potentially enabling spacecraft to maintain much higher average speeds during interplanetary travel while using far less propellant. Note: The engine has only been tested in ground-based vacuum facilities and has not yet flown in space.

📬 The third issue of the WST Chronicle has been published! 🔭 The Wide-Field Spectroscopic Telescope (WST) is a project to build a 12m telescope fully dedicated to multi-object spectroscopy. 📰 The WST Chronicle is an electronic magazine designed to keep the WST science teams and the broader scientific community updated on the latest developments of the project. 📝 This issue includes a contribution co-authored by the #sagateamcamk describing the potential of WST to contribute to exoplanet, stellar and Galactic science in the 2040s. 📡 Among other articles, there is also a discussion about synergies of WST with other future facilities, such as the ELT, the Einstein Telescope, and SKA. https://lnkd.in/dqjz7RgQ #astronomy #astrophysics #scicomm

🎶 Mercury sings in magnetic “birdsong” 🪐 Scientists have discovered that Mercury’s tiny magnetic field produces wave patterns that sound like chirping birds when converted into audio — a phenomenon known as whistler-mode waves. Using data from the BepiColombo mission (ESA–JAXA) and comparing it with Earth’s GEOTAIL spacecraft, researchers found that Mercury generates magnetic “chorus” waves similar to Earth’s — even though its magnetic field is seven times weaker. 🔹 These waves mainly appear on Mercury’s dawn side, where the solar wind strongly disturbs the magnetic field 🔹 Instead of creating auroras (like on Earth), the accelerated electrons strike Mercury’s surface, releasing elements such as sodium and potassium into its exosphere 🔹 This suggests a universal magnetic process shared by planets with magnetic fields This discovery reveals that even the smallest planet has a surprisingly dynamic and musical space environment — shaped by plasma, solar wind, and magnetism. As BepiColombo continues its mission, Mercury may reveal even more “notes” from its invisible magnetic symphony. #Mercury #BepiColombo #PlanetaryScience #SpacePhysics #MagneticFields #Astrophysics #SolarWind #ESA #JAXA #SpaceExploration #ScienceNews #MohammedAltafSayyed

JAXA’s Cloud Profiling Radar - #CPR aboard the #EarthCARE contributes to future climate forecasting and predicting extreme weather. JAXA: Japan Aerospace Exploration Agency - #JAXA, in collaboration with the University of Tokyo - 東京大学 and the Kyushu University - 九州大学 , conducted a comparative study using the CPR data and the high-resolution global cloud-resolving model - #NICAM (Nonhydrostatic Icosahedral Atmospheric Model), which provided insights into vertical atmospheric motion process. The #EarthCARE satellite is the joint earth observation mission by JAXA and the European Space Agency - ESA, and was launched by #Falcon9 in May 2024. <JAXA Press Release: Goolgle Machine Translation into English> https://lnkd.in/g_rpq6GN <Scientific article on ‘scientific reports’> https://lnkd.in/gKP5xEe5 <CPR - EarthCARE website> https://lnkd.in/gfBZPBb7

COADJOINT ORBIT METHOD EVERYWHERE Bosonization of Fermi Surface : The Method of Coadjoint Orbits https://lnkd.in/evhk9QUb Fermi liquid theory is a cornerstone of condensed matter physics. However, Landau's Fermi liquid theory does not fit into the paradigm of effective field theory in that it is formulated in terms of a kinetic equation rather than an action. We describe a new method that leads to a field-theoretical reformulation of Landau Fermi liquid theory. In this approach, a system with a Fermi surface is described as a coadjoint orbit of the group of canonical transformations. The method naturally leads to a nonlinear bosonization of the Fermi surface. The Berry phase that the Fermi surface acquires when changing shape is shown to be given bythe Kirillov-Kostant-Souriau symplectic form on the coadjoint orbit. We show that the resulting local effective field theory captures both linear and nonlinear effects in Landau’s Fermi liquid theory. Possible extensions and applications of the theory are described.
