Mapping Io’s Hidden Heat With NASA’s Juno
NASA's Juno spacecraft used its Microwave Radiometer instrument to map heat on Jupiter's moon Io during two close flybys in December 2023 and January 2024. The black lines show the instrument's footprints from the December 30 flyby that primarily covered the northern hemisphere, while blue lines represent the subsequent January flyby coverage.

Scientists calculated that Venus's clouds' unidentified dark ultraviolet material absorbs light far more strongly than previously thought. This finding narrows possibilities for determining whether the mysterious substance is organic, inorganic, or something unexpected.
Scientists find water was fueling volcanoes 3 billion years ago
Water-rich crustal material sank into Earth's mantle more than three billion years ago through a process called "dripduction," fueling volcanic eruptions. Ancient rocks from Western Australia provided evidence that this water-delivery mechanism operated long before modern plate tectonics fully developed.
Scientists discover a hidden switch that shuts down inflammation
Scientists discovered a natural braking system that switches off inflammation and prevents harmful immune cell buildup. Boosting this pathway in people reduced inflammation-related immune changes and accelerated pain relief.
