How molten carbon crystallizes into either graphite or diamond is relevant to planetary science, materials manufacturing and nuclear fusion research. A new study uses computer simulations to study how molten carbon crystallizes into either graphite or diamond at temperatures and pressures similar to Earth’s interior, challenging the conventional understanding of diamond formation.

The future of sustained space habitation depends on our ability to grow fresh food away from Earth. The revolutionary new collaborative Moon-Rice project is using cutting-edge experimental biology to create an ideal future food crop that can be grown in future deep-space outposts, as well as in extreme environments back on Earth.

If we're to land humans on Mars in the coming decades, we'll have to know what challenges await them when they get there. Enter M-MATISSE, a potential precursor to a crewed mission to the Red Planet which could use UK instrumentation being promoted at the Royal Astronomical Society's National Astronomy Meeting 2025 in Durham to revolutionise our understanding of space weather on Mars. It would involve sending two robot orbiters to the fourth planet from the Sun to unravel the complex workings of the Martian magnetosphere (the region around a planet dominated by its magnetic field), ionosphere (a layer of ionized gas in the upper atmosphere) and thermosphere (where Mars loses its atmospheric gases to space), as well as the planet's lower atmosphere and radiation build-up.

In a paper published in National Science Review, a team of researchers utilized an astronomical telescope equipped with a quantum-limited superconducting mixer as the receiver. The experiment successfully demonstrated real-time high-definition video wireless transmission at 500 GHz over a record distance of 1.2 km at a dry site situated 4445 meters above sea level. This experiment offers valuable insights for the future development of satellite and airborne-to-ground communication technologies and their applications.

A 2.35-billion-year-old meteorite with a unique chemical signature, found in Africa in 2023, plugs a major gap in our understanding of the Moon’s volcanic history.

A new UK-led satellite mission concept aims to strengthen the country's position in space weather observation and forecasting by deploying a suite of homegrown scientific instruments on a low-cost spacecraft in low-Earth orbit. The proposal is being presented today (Wednesday) at the Royal Astronomical Society's National Astronomy Meeting 2025 in Durham. UK-ODESSI (UK-Orbital pathfinDEr for Space-borne, Space-weather Instrumentation) would act as a pathfinder for a new generation of UK-developed space weather instruments.
