Nature Astronomy, Published online: 22 January 2025; doi:10.1038/s41550-024-02470-x In a suborbital experiment and complementary numerical simulations, submillimetre-sized particles bouncing off each other become charged and form centimetre-sized clusters. This mechanism could bridge the size gap in the early planet formation

Nature Astronomy, Published online: 22 January 2025; doi:10.1038/s41550-024-02471-w A suborbital experiment indicates that centimetre-sized clusters of tribocharged submillimetre grains resist erosion by individual grains with collision speeds up to around 0.5 m s–1. The stability of these charged clusters allows them to

Nature Astronomy, Published online: 20 January 2025; doi:10.1038/s41550-024-02467-6 The symmetron model is one of the most compelling theories of dark energy and it has been tested in a laboratory experiment based on a magnetically levitated force sensor. Although no evidence

Nature Astronomy, Published online: 20 January 2025; doi:10.1038/s41550-024-02465-8 One of the possible forms of dark energy is symmetron dark energy, which theoretically interacts with matter via a fifth force. Here a magnetically levitated force sensor is used in an experiment

Nature Astronomy, Published online: 15 January 2025; doi:10.1038/s41550-024-02452-z Coherent radio emission with a long (nearly 6.5 h) period has been detected from both magnetic poles of a rotating compact object, offering insights into the evolution and emission mechanism of compact radio
