Video: 00:12:34 Almost 200 countries are gathering in Dubai to attend the biggest climate event of the year. COP28 – the 2023 United Nations climate change summit – isn’t just another conference though. For the first time, country representatives will assess the progress they’ve made towards cutting their greenhouse gas emissions through a process called the ‘global stocktake’. Satellites are critical in the quest to tackle climate change as they give the robustness and transparency needed to monitor progress towards a lower-emissions and more resilient world. If undertaken effectively, the g ..read more

An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to provide the first observation of water and other molecules in the inner, rocky-planet-forming regions of a disc in one of the most extreme environments in our galaxy ..read more

Video: 00:08:29 Focus on Euclid with Laurent Brouard: “I’m going to show you what a telescope that we send into space looks like.” Laurent Brouard, Project Manager at Airbus Defence and Space, was responsible for building the Euclid payload module (PLM). In this interview, which took place in a clean room at the Airbus premises in Toulouse, he describes with words, gestures, and the Euclid PLM structural and thermal model how Euclid works. Did you know that Euclid sees the same part of the sky at the same time in both the infrared and visible wavelengths? Or that in space radiators keep the i ..read more

Video: 01:00:00 Watch the replay of the media briefing on Ariane 6 during which ESA Director General Josef Aschbacher outlines the progress achieved after the successful hot firing test on 23 November 2023 at Europe’s Spaceport in French Guiana, as well as the upcoming steps in the Ariane 6 development test campaign, including ESA, CNES and ArianeGroup targeting the first launch of Ariane 6 between mid June and end of July 2024. Participants also includes Martin Sion, CEO, ArianeGroup ; Philippe Baptiste, President of CNES and Stéphane Israël, CEO, Arianespace ..read more

Video: 00:02:16 Scenes from the combined hot-fire test held for Ariane 6 on 23 November 2023. Teams on the ground went through a complete launch countdown followed by a seven-minute full firing of the core stage’s engine, as it would fire on a launch into space. This video shows the Ariane 6 mobile building opening its doors, the building rolling away to leave the Ariane 6 test model on the launch pad and the seven minutes of firing. On the launch pad in Kourou, French Guiana, the Ariane 6 test model fired of its Vulcain 2.1 main stage engine for seven minutes. This engine, on a real flight ..read more

Video: 00:02:07 We are all intricately interconnected to our Earth – from the trees that provide us with oxygen, to the natural sources that shape our landscape. ESA's Earth observation programme is at the forefront of monitoring our planet's dynamic changes. Using cutting-edge satellite technology, ESA captures invaluable data on Earth's atmosphere, land and oceans. From tracking climate patterns to assessing environmental health, ESA's Earth observation initiatives provide essential insights for scientific research, environmental management and disaster response. By harnessing space technol ..read more

With all eyes about to focus on the COP28 climate conference in Dubai, new scientific findings show, again, that the climate crisis is taking its toll on Antarctica – a continent, up to recently, thought better able to withstand the immediate effects of rising global temperatures. Using satellite data, scientists have discovered that the ice shelf extending into the ocean from Cadman Glacier on the west Antarctic Peninsula collapsed, leaving the glacier exposed to unusually warm ocean water, which caused the glacier to accelerate and retreat rapidly ..read more

Video: 00:03:08 Henk Hoekstra, professor of observational cosmology at Leiden University, the Netherlands, shares his professional trajectory linked to weak gravitational lensing, a technique used by ESA’s Euclid mission. Henk explains how Euclid will reveal the dark side of the Universe. He uses enlightening examples involving a swimming pool and other terrestrial objects. Listen to Henk Hoekstra to understand how Euclid can make the invisible visible. Space Team Europe is an ESA space community engagement initiative to gather European space actors under the same umbrella sharing values of l ..read more

Image: This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds. HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright inf ..read more
