ESA has reached a significant milestone in its commitment towards a deeper understanding of Earth's dynamic processes and addressing pressing environmental challenges with the selection of two new candidates – Cairt and Wivern – to progress to the next development phase as part of the process of realising the Agency’s eleventh Earth Explorer satellite mission.

The latest image from the NASA/ESA/CSA James Webb Space Telescope shows a portion of the dense centre of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*.

Embracing the New Space approach, it has taken just 36 months to develop and build ESA’s Arctic Weather Satellite. Now complete, this remarkable microsatellite has been shipped from OHB in Sweden to Germany where it is starting a series of tests to make sure that it will survive liftoff next year and its subsequent life in orbit.

The new Galileo satellite model from Thales Alenia Space underwent mechanical and signal performance testing this summer at ESA’s ESTEC Test Centre. Structural models resisted launch-like noise and vibrations while an electrical model proved its ability to send Galileo signals - a major milestone in the development of Galileo’s Second Generation.

A team of university students from University College Dublin is taking Ireland to space, for the very first time. The story begins in 2017, when the team was accepted to ESA's educational CubeSat programme, Fly Your Satellite! Over the course of six years, they have designed, built, and tested the satellite with the help of ESA experts and with access to ESA's state-of-the-art spacecraft testing facilities. As the team prepares for launch and operations, hear more about their journey to this historic moment.

The NASA/ESA Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighbouring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have.

Forty years ago this month, the first European-built Spacelab was launched from Kennedy Space Center, Florida, on board Space Shuttle Columbia. Also on board was Ulf Merbold, who became ESA's first astronaut in space. The 10-day Spacelab-1 mission marked ESA's entry into human spaceflight activities.

Watch the replay of the press conference with ESA project astronaut Marcus Wandt taking place at the European Astronaut Centre in Cologne (Germany) as he prepares for his first mission to the International Space Station.

He was joined by another ESA astronaut, Matthias Maurer. Marcus’s mission, called Muninn, is supported by ESA and the Swedish National Space Agency (SNSA).

The mission will last up to 14 days, in which Marcus will take part in microgravity research and educational outreach activities. Marcus will be a mission specialist on Ax-3 and his launch is scheduled on a SpaceX Dragon spacecraft no earlier than January 2024.

This image, captured on 13 November by the Copernicus Sentinel-2 mission, has been processed using the mission’s shortwave-infrared bands to show the lava flow at the time of acquisition.

Overview of ESA project astronaut Marcus Wandt’s training for his mission to space.

The Swedish astronaut will travel to the International Space Station on Axiom Mission 3 (Ax-3) no earlier than January 2024. He will spend up to 14 days in orbit conducting microgravity research and educational activities.

Marcus Wandt started intensive training for his mission in June 2023. Lessons on payloads and simulators take place in training facilities and space centres around the world. Each of the partners is in charge of training astronauts on the elements that they contribute to the International Space Station.

Marcus’s training in Europe focuses on the Columbus module systems and the experiments he will conduct during his Muninn mission. Marcus spent over 100 hours of training to fully qualify to operate, monitor and maintain Columbus and its experiments.

Spaceflight instructors adjust their lessons to his level and that has helped speed up the training. While he is yet to experience microgravity, Marcus has a solid understanding of flight vehicle systems, their main safety features and how to interpret flight data.

Having satellites in different types of orbit is essential to delivering data to forecast the weather accurately. With the first Meteosat Third Generation Imager satellite safely in geostationary orbit since December 2022, it’s also time to focus on its polar-orbiting cousin, the MetOp Second Generation mission. And now, for the first time, two MetOp Second Generation satellites have been brought together to stand side-by-side for testing.

An enormous burst of gamma rays, detected by ESA’s Integral space telescope, has struck Earth. The blast caused a significant disturbance in our planet’s ionosphere. Such disturbances are usually associated with energetic particle events on the Sun but this one was the result of an exploding star almost two billion light-years away. Analysing the effects of the blast could provide information about the mass extinctions in Earth’s history.

Europe – and the world – is in the midst of the ‘quantum decade’: a period in which the peculiar properties of matter that manifest at the very tiniest of scales are being transformed from mere scientific curiosities into the basis of practical technologies and products. The result? Major leaps forward in communications, navigation, computing and environmental sensing.

The same is true in space: ESA is currently sending a quantum-enabled probe to Jupiter, developing communications based on quantum technologies and planning flying a quantum clock to the International Space Station, as part of its quantum technology cross-cutting initiative.
