An annually resolved tree ring radiocarbon record reveals the 11-year solar cycle in the first millennium BCE, improving understanding of past solar activity and enhancing radiocarbon dating accuracy.

Mechanisms responsible for the electron acceleration to near relativistic energies in Earth’s foreshock remains elusive. Here, the authors show that the combination of resonant scattering by distinct wave modes with known acceleration mechanisms explains the formation of observed electron fluxes up to and above 200 keV.

There is a continuum emission component in the aurorae spectra that is unexplained. Here, the authors show gray-toned continuum emission structures associated with auroral dynamics explains previous continuum emission observations.

Studying long-term dynamics of the global ring currents of Saturn is challenging due to limited measurements. Here, the authors show suprathermal ring currents in Saturn’s magnetosphere varies with a nearly 11-year cycle, which indicates solar cycle related modulation.

NASA’s Parker Solar Probe could solve the mysteries of the solar wind and test Einstein’s theory of relativity.

A new wave of obesity drugs, a multitude of space missions and concern over climate-action policies — we run through what to look out for over the next 12 months.

Amid rapid space-industry growth, Jamie Morin, head of Aerospace’s Center for Space Policy and Strategy, highlights the need for international cooperation.

This week’s excerpts from Nature’s archive feature reviews of a visit to the Lick Observatory in California and a children’s adaptation of a book on anthropology.

Detecting and interpreting methane emissions from space is not enough. A comprehensive approach is needed.

Astronomer Desireé Cotto-Figueora detects and characterizes near-Earth asteroids to identify potential hazards.
