A new study explores the possibility that Europa’s geysers erupt from shallow reservoirs filled with icy liquid — a possibility that upcoming space missions should be able to explore further.

The upcoming Dragonfly mission’s seismic instruments should be able to distinguish between a shell made of pure water ice and one in which methane molecules are trapped within the crystal structure of water ice.

Researchers have digitized measurements from Voyager to provide a new estimate of an important reference temperature in Jupiter’s atmosphere; the new estimate is 4K hotter than the previous temperature.

At long last, blazars have been unambiguously linked to the production of neutrinos with a chance probability of just 6 × 10^-7, bringing years of controversy and debate to a conclusion.

Researchers test the accuracy of a new standard candle by measuring the distance to the Triangulum Galaxy and show it to be a viable way to make a local measurement of the Hubble constant with JWST.

The miniaturized spectrometer and optical head of the Ma_MISS experiment will be able to distinguish single 100-micron-size grains within the hole excavated for sample analysis of the martian surface.
