Image: 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. These so-called mini-Neptunes are unlike any planet in our Solar System and provide a ‘missing link’ between Earth-like and Neptune-like planets that is not yet understood. Mini-Neptunes are among the most common types of exoplanets known, and astronomers are starting to find more and more orbiting bright stars. Mini-Neptunes are mysterious objects. They are smaller, cooler, and more difficult to find than the so-called hot Jupiter exoplanets w…

Video: 00:13:21 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. If space debris – uncontrolled human-made objects such as spent upper stages of rockets and pieces of satellites – hits a satellite, it could cause serious damage, which can even end a mission (as has happened in the past). If debris crashes on Earth’s surface, it could potentially hit populated areas. In this second v…

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. View the full article

Video: 00:12:38 Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions, such as unique spacecraft technologies. In this first video, Nicolas recalls how he and his team had to think outside the box to find a solution for ESA to communicate with Ulysses. The spacecraft was flying around the north pole of the Sun, which is much farther in deep space than satellites had been launched up to that point. The success of this solution motivated the decision to build ESA’s first deep-space communications antennas in New Norcia, in Australia, thus enabling many ESA scientific firsts in deep-space exploration. The a…

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. View the full article

Image: 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. This portrait of NGC 5068 is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. Previous gems from this collection can be seen here and here. These observations are particularly valuable to astronomers for two reasons. The first is…

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. ESA has now concluded its initial phase of a pilot initiative in Austria that demonstrates the untapped potential of space technologies by providing actionable Earth observation information to accelerate the Green Transition for both society and the economy.

Everything burns. Given the right environment, all matter can burn by adding oxygen, but finding the right mix and generating enough heat makes some materials combust more easily than others. Researchers interested in knowing more about a type of fire called discrete burning used ESA’s microgravity experiment facilities to investigate. View the full article

Interaction between moon’s plumes and Saturn’s ring system explored with WebbA water vapour plume from Saturn’s moon Enceladus spanning more than 9600 kilometres — long enough to stretch across the Eurasian continent from Ireland to Japan — has been detected by researchers using the NASA/ESA/CSA James Webb Space Telescope. Not only is this the first time such water ejection has been seen over such an expansive distance, but Webb is also giving scientists a direct look, for the first time, at how this emission feeds the water supply for the entire system of Saturn and its rings.
