Imagine you are singing in a choir. You are doing your best, just like everybody else. Suddenly, somebody turns to you and points out that you are not singing the right note. If you are told off in a harsh way, you may feel bad about it, and if this happens too often you might not only feel upset about the choir but might even leave it for good. Eventually, the whole choir could end if everybody just leaves.

ESA’s exoplanet mission Cheops confirmed the existence of four warm exoplanets orbiting four stars in our Milky Way. These exoplanets have sizes between Earth and Neptune and orbit their stars closer than Mercury our Sun.

25 years ago, Copernicus set out to transform the way we see our planet. It is the largest environmental monitoring programme in the world. Learn more about the Copernicus programme and the Sentinel satellite missions developed by ESA.

Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.
Twenty-five years ago, Copernicus set out to transform the way we see our planet. Now, well established as the largest environmental monitoring programme in the world, it returns a whopping 16 terabytes of high-quality data every single day. To mark a quarter-century of European success in space, we look back at a selection of 25 Copernicus highlights.

Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions, such as unique spacecraft technologies.
The food we eat determines how we feel, and nothing beats a good fry-up, although in moderation of course. As we prepare for missions to the Moon and on to Mars, astronauts will be happy to hear from researchers that one staple comfort food is not out of reach, even in space: fries.

A delicate tracery of dust and bright star clusters threads across this image from the NASA/ESA/CSA James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.
A new mosaic of Mars marks 20 years since the launch of ESA's Mars Express, and reveals the planet’s colour and composition in spectacular detail.

Join us live to follow the ‘Ready for the Moon’ event, a high-level political conference on the challenges and ambitions for Europe's space sector. ESA Web TV will broadcast on its Channel Two the conference, including the media briefing on 2 June starting at 14:00 CEST (13:00 BST).
Earth observation has been essential in identifying and monitoring climate change. Satellite data form the baseline for effective European mitigation and adaptation strategies to support the Green Transition, the European Union to reach its goal of becoming carbon neutral by 2050, as well as its Green Deal.
