The European Space Agency says science operations have begun for Smile, the Solar wind Magnetosphere Ionosphere Link Explorer. The mission, developed with the Chinese Academy of Sciences, will study the interaction between the solar wind and Earth's magnetic field. Announcing the milestone, ESA said the spacecraft has completed commissioning and is now delivering its first scientific data from orbit.

The SMILE satellite has ended an 18-year gap in observations of the northern lights, and researchers say new views of Earth's x-ray magnetic shield are just weeks away. The mission is expected to provide fresh insight into how the solar wind interacts with Earth's magnetic field, producing auroras. Space science outlets are highlighting the milestone and the images anticipated in the coming weeks.

The Sunrise-III stratospheric observatory, a solar telescope flown on a balloon, has returned new observations revealing detailed magnetic structures on the Sun's surface. Reports from science outlets including Phys.org and EurekAlert, along with Japan's National Astronomical Observatory, describe images capturing fine-scale magnetic fields in unprecedented detail. Researchers say the findings help explain how solar magnetism drives activity such as flares and eruptions that can affect Earth.

Astronomers report that enigmatic flashes of X-rays in the sky may come from the catastrophic merger of two stars, producing an ultra-dense, ultra-magnetic remnant known as a magnetar. The findings emerged from a collaboration between Chinese and European science missions, and are drawing attention among space researchers and enthusiasts discussing what the discovery reveals about how magnetars form.

Physicists have identified a new form of magnetism known as octupolar magnetism, in which magnetic ordering arises from higher-order, octupole moments rather than ordinary dipole spins. The finding expands the known classes of magnetic materials and could inform the development of quantum technologies, where such exotic magnetic states may be harnessed for future devices. Details of the research were reported by science outlets this week.

A science explainer is drawing wide attention with the claim that scientists have found a hole above Earth. The headline, circulating globally in multiple languages, refers to an atmospheric or magnetic anomaly detected by researchers, though the specific findings are not detailed in available coverage.
