  • The long-term cooling of Earth's mantle is recorded in the declining temperature and volume of its volcanic outpourings over time. However, analyses of 89-million-year-old lavas from Costa Rica suggest that extremely hot mantle still lurks below.

  • The composition of the volcanic gas supplied to Venus’s atmosphere indicates that the planet has a dry interior and is unlikely to have condensed liquid water on its surface, substantially constraining its potential habitability.

  • According to astrophysical and geological models, cosmic dust rich in bioessential elements could have accumulated on the surface of early Earth in arid environments (such as glaciers), potentially helping to foster the chemical origins of life.

  • Observations from the JWST show the presence of a spectral absorption feature at 4.05 μm arising from SO2 in the atmosphere of the gas giant exoplanet WASP-39b, which is produced by photochemical processes and verified by numerical models.

  • ALMA observations of the protoplanetary disk around HD 100546 reveal an unexpected C/O variation with azimuth. The carbon-dominated wedge of the disk can be reproduced via a model with a shadowing mechanism.

  • Magma ascent from the near-Moho depth of 24 km to surface eruption took 10 days with melt transport rates of 0.02 to 0.1 m s−1, according to geothermobarometry and diffusion chronometry on primitive olivine crystals from Borgarhraun, Iceland.
