Ejected Surface Regolith as a Potential Source Material for Centaur Rings
The Planetary Science JournalRing systems have been observed around Centaur Chariklo (10199) and other small bodies but their origin and dynamical histories are still debated. These small body ring systems challenge conventional models for the origin of planetary rings, especially ...

Advanced Science, EarlyView.A robust, substrate‐independent fabrication approach overcomes the spectral and geometric limitations of traditional stray‐light suppression. By combining ink spray‐coating with self‐assembled microsphere mask etching, this method produces parabolic‐shaped microstructures on diverse planar and curved engineering components.

Assessing the Role of Large Fullerenes as Potential Carriers of Infrared Emission Plateaus
The Astrophysical JournalWe investigate large fullerenes containing between 90 and 1750 carbon atoms and with radii ranging from 4.4 to 12.9 Å, and compare their computed emission spectra to Spitzer data for the fullerene-rich planetary nebulae SMP SMC 24 and SMP LMC 48 to ...

Advanced Science, EarlyView.Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine

Investigating Tidal Stripping of a Preexisting Moon as the Origin of Saturn’s Young Icy Rings
The Astrophysical Journal LettersThe origin of Saturn’s rings has been debated for decades. Measurements from Voyager and Cassini have suggested that the rings could be as young as ∼100 Myr and composed of nearly pure ice. Several scenarios have been proposed to explain these properties.

GalaxiesI demonstrate the usage of planetary nebulae (PNe) to infer that a pair of jets shaped the ejecta of the core-collapse supernova (CCSN) SN 1987A. The main structure of the SN 1987A inner ejecta, the ‘keyhole’, comprises two low-intensity zones.

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance
Advanced Science, EarlyView.Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Spectral Trends across the Rings and Inner Moons of Uranus and Neptune from JWST NIRCam Images
The Planetary Science JournalJWST NIRCam images provide low-resolution spectra of the rings and inner moons orbiting Uranus and Neptune. These data reveal systematic variations in spectral parameters like the strength of the strong OH absorption band around 3 μ m and the spectral ...

Eos, Transactions American Geophysical Union, 2008 Life used to be simple for ring scientists. Since the time of Galileo, anyone with even the most basic telescope could see that Saturn was the only planet with rings. Saturn's ring system is clearly bright, broad, and bland. James Clerk Maxwell proved that the rings could not be solid, and basic spectroscopy showed that they are composed primarily of ...
