Astronomers using the NASA/ESA/CSA James Webb Space Telescope together with the NASA/ESA Hubble Space Telescope have looked deeply at thousands of young star clusters in four nearby galaxies, studying clusters at different stages of evolution. Their findings show that more massive star clusters emerge more quickly from the clouds they are born in, clearing away gas and filling the galaxy with ultraviolet light. The result gives us a better understanding of star formation in galaxies, as well as how and where planets can form.

The European Space Agency (ESA) has partnered with French video game studio DON’T NOD Entertainment on the development of Aphelion, a narrative science‑fiction game inspired by space exploration and scientic expertise.

Thirteen European satellites on the same rideshare launcher have successfully reached orbit, bringing capabilities to Italian and Greek monitoring programmes as well as CubeSats that will test satellite connectivity.

The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase.

With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission – a journey that began more than a decade ago and that has helped pave the way for the future of Earth observation.

What did space deliver for Europe this month? From the Moon to low Earth orbit and beyond, here’s what the European Space Agency has been up to.
