- 1New asymptotic approach to modelling wind-drift ocean currents▼On large-scale wind-drift ocean currents: An asymptotic approach in spherical coordinates
A mathematical study on large-scale wind-drift ocean currents has been published, presenting an asymptotic approach formulated in spherical coordinates for describing how winds drive major ocean circulation. The work offers a theoretical framework intended to improve the representation of wind-driven currents at global scale, where traditional Cartesian approximations become less accurate. Specialists in physical oceanography and geophysical fluid dynamics are the likely audience for the paper.

New observations from NASA's Juno spacecraft show the intricate fluid dynamics at Jupiter's north pole, where a stable ring of circumpolar cyclones has persisted. Each storm system is nearly the size of Earth, and the findings highlight how these massive atmospheric vortices remain organised without merging, deepening scientists' understanding of giant planet weather.

NASA's Perseverance Mars rover has found evidence of groundwater, lakes, and hot fluids coexisting in a single location on the Red Planet. The finding points to a dynamic ancient environment where liquid water and geothermal activity overlapped, with implications for Mars' past habitability.
