XRISM has directly traced stellar-wind plasma falling towards neutron-star pulsar GX 301-2. Learn how gravity captures the gas, why accretion changes during the orbit, and how X-ray spectroscopy measures the flow.
Hubble has revealed an evolving 10-sided atmospheric wave around Saturn’s south pole. Learn what scientists know, how jet-stream waves can form polygonal patterns, and why the decagon differs from Saturn’s famous northern hexagon.
What really happens when a satellite returns through Earth’s atmosphere? Explore heating, fragmentation, targeted re-entry and how ESA’s Cluster observations can improve safer spacecraft design.
Explore how ancient lake water, groundwater and hydrothermal fluids left different geological clues in Jezero Crater—and how Perseverance reads that history.
Learn how the Cocoon Nebula can be an emission, reflection and dark nebula at the same time, why dust hides stars, and how dense clouds form new stars.
Earth’s centre of mass shifts slightly as water, ice and atmosphere redistribute. Learn what the geocentre is and why millimetre-scale changes matter for satellites.
Learn how lunar impact craters form, why fresh ejecta looks bright, how secondary craters develop, and how NASA’s LRO finds new impacts by comparing before-and-after images.
Learn how GX 301-2 captures part of Wray 977’s stellar wind, how temporary accretion forms, and how XRISM spectroscopy revealed plasma falling toward the pulsar.
What is a brown dwarf? Webb has identified objects in IC 348 with masses around twice Jupiter's, helping astronomers test how the smallest star-like bodies form.
NASA has activated Roman's 300-megapixel Wide Field Instrument in space. Learn how its 18 detectors, wide field of view and infrared sensitivity enable enormous astronomical surveys.
Mercury is relatively close to Earth, yet placing a spacecraft in orbit there is extraordinarily difficult. Here is how BepiColombo uses gravity assists, efficient propulsion and careful braking to arrive.
Learn why auroras glow green, red, blue, pink and purple, how oxygen and nitrogen create the colours, and why auroras can be more active near equinoxes.
