The NASA/ESA/CSA James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, occurred 160 000 light-years from Earth in the Large Magellanic Cloud. SN 1987A was observed on Earth in 1987, the first supernova that was visible to the naked eye since 1604 — before the advent of telescopes.

Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Monitoring the cryosphere is crucial for assessing, predicting and adapting to climate change.

Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon dioxide, as well as knock-on issues such as ocean acidification, is key for understanding climate change and for taking effective action.

Further embracing the New Space era, ESA is to develop two new Scout satellites: NanoMagSat and Tango. NanoMagSat will measure Earth’s magnetic field to help assess space weather hazards and continue on from ESA’s current Swarm mission. Tango will measure greenhouse-gas emissions from human activity and complements the upcoming Copernicus Carbon Dioxide Monitoring mission and the Sentinel-5 mission, as well as the current Sentinel-5P mission.

It's 'Lights, camera and... action!' for ESA as the agency launches Film ESA, a dedicated film location guide.

Today, ESA’s space telescope Euclid begins its survey of the dark Universe. Over the next six years, Euclid will observe billions of galaxies across 10 billion years of cosmic history. Learn how the team prepared Euclid in the months after launch for this gigantic cosmic quest.

The Po Valley, nestled in northern Italy, is renowned for its picturesque landscapes and rich agricultural history. However, the region is also grappling with a persistent environmental challenge: air pollution. The unique geographical and meteorological conditions of the Po Valley contribute to fluctuations in air quality – impacting the health of its residents.
