A New Concept for Catching Up with 3I/ATLAS
The third interstellar object detected in our Solar System (3I/ATLAS) has a unique and continually unfolding story to tell of its nature and origin. In a recent paper, scientists from the i4is show how a spacecraft performing a Solar Oberth Manoeuvre (SOM) could intercept 3I/ATLAS to learn its secrets.
The Little Moon with a Giant Electromagnetic Punch
Saturn's tiny moon Enceladus, famous for its water geysers, has been revealed as a giant electromagnetic powerhouse whose influence extends over half a million kilometres through the ringed planet's magnetosphere. Analysis of 13 years of Cassini data shows the 500 kilometre wide moon creates a lattice like structure of crisscrossing electromagnetic waves known as Alfvén wings, that bounce between Saturn's ionosphere and the plasma torus surrounding Enceladus's orbit, reaching distances 2,000 times the moon's own radius. It changes our understanding of how small icy moons can influence their giant planetary hosts, with implications for the moons of Jupiter and perhaps even distant exoplanetary systems.
Earth's Radiation Fingerprint
Scientists have discovered a revolutionary way to measure Earth's radiation budget by observing our planet from the Moon. A team of astronomers have revealed that lunar observations capture Earth as a complete disk, filtering out local weather noise and revealing planet scale radiation patterns dominated by spherical harmonic functions, effectively creating a unique "fingerprint" of Earth's outgoing radiation. This Moon based perspective solves fundamental limitations of satellite observations, which struggle to achieve both temporal continuity and spatial consistency, offering a new tool for understanding global climate change with unprecedented clarity.
The Ariane 6 Rocket Gets More "Oomph!"
Designed for versatility, Ariane 6 can adapt to each mission: flying with two boosters for lighter payloads, or four boosters when more power is needed. In its four-booster configuration, Ariane 6 can carry larger and heavier spacecraft into orbit, enabling some of Europe’s most ambitious missions.

Hunting Cosmic Ghosts from the Edge of Space
After five years of development and a nail biting launch from Antarctica, the PUEO experiment has completed a 23 day balloon flight at the edge of space, hunting for some of the most energetic particles in the universe. The instrument flew at 120,000 feet above Antarctica, using the entire continent as a detector to search for ultra high energy neutrinos, elusive particles that could reveal secrets about the universe’s most violent events. Now safely back on the ice with 50-60 terabytes of data, scientists are preparing to search through the results to see if they’ve caught these messengers from distant galaxies.
The Mystery of the Fading Star
Astronomers have solved the mystery of a star that dimmed dramatically for nearly 200 days, one of the longest stellar dimming events ever recorded. The culprit appears to be either a brown dwarf or a super Jupiter with an enormous ring system, creating a giant saucer like structure that blocked 97% of the star’s light as it passed in front. This rare alignment offers scientists a unique opportunity to study planetary scale ring systems far beyond our Solar System.
The Hidden Story of Young Martian Volcanoes
New research has revealed that Mars’ most recent volcanoes weren’t formed by simple, one off eruptions as scientists previously thought. Instead, these volcanic systems evolved over millions of years, fed by complex underground magma chambers that changed and developed over time. By studying surface features and mineral signatures from orbit, researchers have pieced together a far more intricate volcanic story than anyone expected.
Comet 29P/Schwassmann-Wachmann Bursts as "Ice Volcano" Erupts
After a recent explosive outburst, Comet 29P/Schwassmann-Wachmann is bright enough to see in a medium-sized telescope.

Webb Reveals a Plethora of Organic Molecules in a Bright Local Infrared Galaxy
A recent study, led by the Center for Astrobiology (CAB), CSIC-INTA and using modelling techniques developed at the University of Oxford, has uncovered an unprecedented richness of small organic molecules in the deeply obscured nucleus of a nearby galaxy, thanks to observations made with the James Webb Space Telescope (JWST). The work, published in Nature Astronomy, provides new insights into how complex organic molecules and carbon are processed in some of the most extreme environments in the Universe.
