During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 930 miles (1,500 kilometers) above the moon, Io’s night side [left lobe] is illuminated by “Jupitershine,” which is sunlight reflected from the planet’s surface.

This image is the NASA Science Image of the Month for October 2025. Each month, NASA’s Science Mission Directorate chooses an image to feature, offering desktop wallpaper downloads, as well as links to related topics, activities, and games.

Camels in ancient Arabia may have led hunter-gatherers through deserts once thought uninhabitable

The Habitable Worlds Observatory is poised to tell us whether Earth-like planets are common—if it can get off the ground

China’s plan to reduce greenhouse gases will largely determine the world’s emissions trajectory, researchers say

Our Milky Way galaxy never sits still: it rotates and wobbles. And now, data from the European Space Agency’s Gaia space telescope reveal that our galaxy also has a giant wave rippling outwards from its centre.

The black hole at the centre of a galaxy more than 50 million light years away is spewing out a jet of extremely hot plasma – though we have studied it for a century, we are only now seeing it in great detail

Scientists found new gecko species hidden in plain sight in pristine deserts of southern Africa, thanks to their loud, barking mating calls

The European Space Agency (ESA) and the Australian Space Agency (ASA) will pursue new ways of working together following discussions during the 76th International Astronautical Congress in Sydney, Australia.

A new article published in The Astrophysical Journal explores a new theory of how Type Ia supernovae, the powerful stellar explosions that astronomers use to measure distances across the universe, might be triggered. Traditionally, these supernovae occur when a white dwarf star explodes after interacting with a companion star. But this explanation has limitations, leaving open questions about how these events line up with the consistent patterns astronomers actually observe.

A study of Saturn's atmospheric structure using data from the James Webb Space Telescope (JWST) has revealed complex and mysterious features unseen before on any planet in our Solar System. The results were presented last week by Professor Tom Stallard of Northumbria University, at the EPSC-DPS2025 Joint Meeting in Helsinki.

Mars holds a special place in my heart being the second planet I saw through a telescope. It’s probably fair to say that it’s held a special place for many as we continue to explore the fascinating world that is the red planet. Scientists studying Mars have recently uncovered a seasonal phenomenon that could change our understanding of the potential for it to support life. Their discovery, a swirling polar vortex that forms of the Martian north pole every winter.
