The Italian region of Emilia-Romagna was devastated by severe floods in May 2023, claiming lives and displacing thousands of people, resulting in an estimated €8.8 billion in damages. With the region still grappling with the aftermath, satellites have been instrumental in assessing the damages of the affected areas.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has observed the chemical signature of carbon-rich dust grains at redshift ~ 7 [1], which is roughly equivalent to one billion years after the birth of the Universe [2]. Similar observational signatures have been observed in the much more recent Universe, attributed to complex, carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). It is not thought likely, however, that PAHs would have developed within the first billion years of cosmic time.

ESA's Mars Express has revisited an old favourite: the distinctive and fascinating Mawrth Vallis, one of the most promising locations on Mars in our search for signs of life.

After completing its mission in orbit, ESA’s wind mission Aeolus will soon reenter Earth's atmosphere. Currently orbiting 320 km above, Aeolus is being kept in orbit with its remaining fuel. This fuel is running out, and the satellite will soon succumb to Earth’s atmosphere and gravity.  

Fuelled largely by climate change, our planet is being subjected to environmental changes that are having an unprecedented global impact on humans, animals and plants. Shockingly, in certain locations these changes are occurring at a rate never before witnessed.

After almost five years, ESA’s Aeolus wind satellite has completed its mission. Now, you can listen to the Life of Aeolus – an incredible wind orchestral piece that has been composed using data spanning Aeolus’ entire life in orbit around Earth.

Isn’t it strange that when satellites run out of fuel or a single component breaks down, we just discard them? ESA and European industry have joined forces to make sure that our satellites can live on.

In March, we announced that 2023 would see the publication of over 300 vacancies at ESA. New vacancies keep being published as we continue our search for talented and motivated professionals to join our teams across Europe and support our mission of the peaceful exploration of space for the benefit of everyone. Could ESA be the next step in your career? Read more to find out!

Temperatures are sizzling across Europe this week amid an intense and prolonged period of heat. And it’s only just begun. Italy, Spain, France, Germany and Poland are all facing a major heatwave with temperatures expected to climb to 48°C on the islands of Sicily and Sardinia – potentially the hottest temperatures ever recorded in Europe.
