Why does Mercury have such a big iron core? Magnetism!

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run collisions with other bodies during the formation of our solar system blew away much of Mercury's rocky mantle and left the big, dense, metal core inside. But new research reveals that collisions are not to blame—the sun's magnetism is.

First high-altitude drop test success for ExoMars parachute

After several weeks of bad weather and strong winds, the latest pair of high-altitude drop tests of the ExoMars parachutes took place in Kiruna, Sweden. The 15 m-wide first stage main parachute performed flawlessly at supersonic speeds, while the 35 m-wide second stage parachute experienced one minor damage, but decelerated the mock-up of the landing platform as expected.

Observation, simulation, and AI join forces to reveal a clear universe

Japanese astronomers have developed a new artificial intelligence (AI) technique to remove noise in astronomical data due to random variations in galaxy shapes. After extensive training and testing on large mock data created by supercomputer simulations, they then applied this new tool to actual data from Japan's Subaru Telescope and found that the mass distribution derived from using this method is consistent with the currently accepted models of the Universe. This is a powerful new tool for analyzing big data from current and planned astronomy surveys.

Solar hydrogen for Antarctica: The advantages of thermally coupled approach

A team from the Helmholtz-Zentrum Berlin, Ulm University, and Heidelberg University has now investigated how hydrogen can be produced at the South Pole using sunlight, and which method is the most promising. Their conclusion: in extremely cold regions, it can be considerably more efficient to attach the PV modules directly to the electrolyser, i.e. to thermally couple them. This is because the waste heat from the PV modules increases the efficiency of electrolysis in this environment. The results of this study, which has now been published in Energy & Environmental Science, are also relevant for other cold regions on Earth, such as Alaska, Canada, and high mountain regions, for example. In these places, solar hydrogen could replace fossil fuels such as oil and petrol.
