NASA astronauts Jonny Kim and Zena Cardman, both Expedition 73 Flight Engineers, pose for a portrait inside the International Space Station’s Unity module during a break in weekend housecleaning and maintenance activities. Kim and Cardman are both part of NASA Astronaut Group 22 selected in June 2017 with 12 other astronauts, including two Canadian Space Agency astronauts, and affectionately nicknamed “The Turtles.”

Galileo ‘daughter mission’ name revealed: Celeste
Following the announcement of the upcoming launch of LEO-PNT’s first satellites, ESA has now unveiled the name of the mission. Celeste, as it has been officially designated, will test the potential of a new, low Earth orbit layer of satellites to enhance Galileo’s resilience and complement its capabilities.

ESA observations of interstellar comet 3I/ATLAS
The European Space Agency (ESA) reacted promptly to the discovery of comet 3I/ATLAS on 1 July 2025. Soon after they were alerted to its existence by automated detection systems, ESA astronomers began using ground-based telescopes in Hawaii, Chile, and Australia to monitor its progress.
Since then, the comet has been observed by space telescopes close to Earth, including the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope.
In the coming months, ESA will turn interplanetary voyagers such as Mars Express, ExoMars Trace Gas Orbiter and the Jupiter Icy Moons Explorer (Juice) in the direction of the comet to make further observations from excellent vantage points.

Double trouble: Solar Orbiter traces superfast electrons back to Sun
The European Space Agency-led Solar Orbiter mission has split the flood of energetic particles flung out into space from the Sun into two groups, tracing each back to a different kind of outburst from our star.

Landsat 9 Sees Buccaneer Archipelago
In the sparsely populated Kimberley region of Western Australia, jagged landforms reach like fingers into the turquoise-blue ocean waters. Along the coastline north of Derby, they used to reach even farther. But rising sea levels submerged part of the coastal landscape, giving rise to hundreds of islands and low-lying reefs that compose the Buccaneer Archipelago.

Dusty wisps round a dusty disc
For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disc located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation.
