Three-dimensional modeling of lightning-induced electromagnetic pulses on Venus, Jupiter and Saturn
, 2018 While lightning activity in Venus is still controversial, its existence in Jupiter and Saturn was first detected by the Voyager missions and later on confirmed by Cassini and New Horizons optical recordings in the case of Jupiter, and recently by Cassini

Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen
Physik in unserer Zeit, EarlyView.Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.

Physik in unserer Zeit, EarlyView.Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...

Jupiter: Giant of the solar system [PDF]
Jupiter, its relationship to the other planets in the solar system, its twelve natural satellites, solar orbit and the appearance of Jupiter in the sky, and the sightings and motions of Jupiter in 1973 are discussed.

Remote Sensing in Ecology and Conservation, EarlyView.Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

High resolution observations of Jovian magnetospheric microwave synchrotron emission [PDF]
High resolution radio observations of Jupiter were investigated with the use of the Stanford synthesis telescope. The best fit disk was computed from the emission of Jupiter and the residual brightness, due to nonthermal mechanisms was ...

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
SmartBot, EarlyView.Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Interplanetary MeV electrons of Jovian origin [PDF]
Observations of low energy electron increases observed in interplanetary space on Pioneer 10 are reported as it approached Jupiter. These discrete bursts were several hundred times the normal quiet-time electron flux, and became more frequent as one ...

Small, EarlyView.Ultracentrifugation‐assisted phosphate–sulfate treatment induces self‐limiting nano‐pitting on carbon nanotube surfaces, creating confined sites for in situ growth of Na2.85V2(PO4)2.85(SO4)0.15 nanodots. This embedded nanodot–carbon interface ensures strong electronic coupling and short ion pathways, enabling capacitor‐like sodium storage with ...
