NASA astronaut Nichole Ayers captured this image of lightning while orbiting aboard the International Space Station more than 250 miles above Milan, Italy on July 1, 2025. Storm observations from space station help scientists study Earth’s upper atmosphere, which can improve weather models and protect communication systems and aircraft. Space station crew take photographs of Earth that record how the planet changes over time due to human activity and natural events. This record allows scientists to monitor disasters and direct response on the ground and study phenomena.

It was a question I heard lots this past weekend. “What’s that bright star near the Full Moon?” That ‘star’ was actually a planet, as Jupiter heads towards opposition rising ‘opposite’ to the setting Sun this coming weekend. This places the King of the Planets high in the northern sky, in the same general spot the Full Moon occupies in January.

The extent and speed of ice moving off the ice sheets of Greenland and Antarctica into the sea – an important dynamic for climate and sea-rise modelling – has been captured over a 10-year period by satellites from the Copernicus Sentinel-1 mission.

Martian winds can have quite an impact. ESA’s Mars Express has spotted them whipping up sand grains and acting as a cosmic sandblaster, carving out intriguing grooves near Mars’s equator.
