A massive filament eruption carved a 250,000-mile-long "canyon of fire" into the sun — and sent a CME sailing into space.

In human beings, egg cells need to survive for about five decades, much longer than most other cell types – and they may achieve this unusually long lifespan by slowing down their natural cell processes

The impact that carved out the moon's huge South Pole-Aitken basin may explain the puzzling differences between the lunar near and far sides.

View of Earth as seen by ESA project astronaut Sławosz Uznański-Wiśniewski inside the seven-windowed cupola, the International Space Station's "window to the world".

The European Space Agency-built Cupola is the favourite place of many astronauts on the International Space Station. It serves not only as a unique photo spot, but also for observing robotic activities of the Canadian Space Agency's robotic arm Canadarm2, arriving spacecraft and spacewalks.

Sławosz was launched to the International Space Station on the Dragon spacecraft as part of Axiom Mission 4 on 25 June 2025. The 20-day mission on board is known as Ignis.
During the Ignis mission, Sławosz conducted 13 experiments proposed by Polish companies and institutions and developed in collaboration with ESA, along with three additional ESA-led experiments. These covered a broad range of areas including human research, materials science, biology, biotechnology and technology demonstrations.  

The Ax-4 mission marks the second commercial human spaceflight for an ESA project astronaut. Ignis was sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT) and the Polish Space Agency (POLSA).
