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.

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.

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.
