Seas of the Sun: The story of Cluster
What began with tragedy ended in triumph. This is the untold story of the European Space Agency’s pioneering 25-year Cluster mission to study how invisible solar storms impact Earth's environment.
Like a ship in a never-ending storm, Earth is bombarded by swarms of particles ejected from the Sun at supersonic speeds. Most of these solar wind particles are deflected by the magnetosphere and sail harmlessly by, but Earth’s shield is not bulletproof.
Since 2000, Cluster sailed the seas of the Sun and revealed the complexities of the Sun–Earth connection. After two-and-a-half incredibly successful decades in space, ESA took the decision to safely deorbit the four Cluster satellites throughout 2024–2026. The mission officially ended on 8 September 2024.
But a space mission is so much more than science. Experience Cluster’s story as told by the people who lived it: scientists and engineers Arnoud Masson, C. Philippe Escoubet, Gill Watson, Gunther Lautenschläger, Lean-Nani Alconcel, Bruno Sousa, Paulo Ferri, Patrick W. Daly, Mandred Warhaut, Silvia Sanvido and Jolene S. Pickett.
The film was produced by Space Rocks for the European Space Agency. It features an original soundtrack by Karlotta Skagfield and additional music by Bruce Dickinson.

This Week's Sky at a Glance, October 30 –November 9
Saturn is in excellent view all evening. In a telescope its rings look like a thin needle piercing the big yellow globe. Soon the rings will turn exactly edge-on.

A Mundane Universe and the Rarity of Advanced Civilizations
How could the principle of “radical mundanity” proposed by the Fermi paradox help explain why humans haven’t found evidence of extraterrestrial technological civilizations (ETCs)? This is what a recently submitted study hopes to address as a lone researcher investigated the prospect for finding ETCs based on this principle. This study has the potential to help scientists and the public better understand why we haven’t identified intelligent life beyond Earth and how we might narrow the search for it.

The Keen-Eyed Vera Rubin Observatory Has Discovered A Massive Stellar Stream
The Vera Rubin Observatory saw first light in June 2025. Its images from that time are called the Virgo First Look images because they focus on the Virgo Cluster of galaxies. M61 is one of the galaxies in that cluster, and the VRO has detected a stellar stream of stars around the distant spiral galaxy in Rubin's images.
