Complex morphology of subducted lithosphere in the mantle beneath the Tonga trench

Article Abstract:

The extension of the Pacific plate deep into the Earth's mantle is complex and descends along a trajectory. The complex nature of the extension is revealed in the seismic tomographic studies of the Tonga trench in the old Pacific sea floor. The extension occurs without a kink and the characteristic slab morphology is attributed to the subduction system's tectonic evolution.

High-velocity streams of dust originating from Saturn

Article Abstract:

High-velocity submicrometre-sized dust particles expelled from the Jovian system are identified by dust detectors on board several spacecraft. The discovery by the Cassini spacecraft of burst of high-velocity dust particles within ~70 million kilometers of Saturn is reported.
