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 technology, ESA contributes significantly to our understanding of Earth – ensuri…

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.

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 leadership, autonomy, and responsibility.

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 infrared objects in the upper portion of the image are thought to host two further protosta…

ESA’s first human spaceflight mission lifted off 40 years ago today. Accompanied by the first ESA astronaut, Ulf Merbold, the Spacelab module took flight inside the Space Shuttle’s cargo bay, turning NASA’s ‘space truck’ into a mini-space station for scientific research. Europe continues to be highly active in the crewed module business to this day. View the full article

Video: 00:07:54 Focus on Euclid with Jean-Charles Cuillandre: “What we see in the first Euclid images is a promise of what will come in the future.” Jean-Charles Cuillandre, astronomer at CEA Paris-Saclay, explains that he was “blown away” when he saw the first full-colour images captured by ESA’s recently launched Euclid space telescope. Being a specialist of wide-field imaging, Jean-Charles was not only involved in the programme committee that selected the celestial targets for the ESA Euclid’s ‘Early Release Observations’, but he was also in charge of processing the data both for their scientific and their outreach value. Jean-Charles expected the resulting im…

Video: 00:01:25 Cinq, quatre, trois, deux, un. Allumage Vulcain! This is the moment Ariane 6’s main engine was sparked into life, and the entire main stage of the new rocket and the many parts of the launch pad in Kourou, French Guiana, practised for the full duration of a launch. Of course, as planned, the test model did not leave the ground. Without its boosters, instead of piercing the clouds Ariane 6’ created its own on Earth: a clean byproduct of the Vulcain 2.1 engine’s oxygen and hydrogen propellants, which came together to send out impressive swirls of H2O. After the almost 150 tonnes of propellant was burnt through and the clouds dispersed, the curtains c…

Video: 00:08:32 On 23 November 2023, in preparation for its first flight, Ariane 6 went through its biggest test to date: a full-scale rehearsal that meant complex fuelling, a launch countdown and ignition of the core stage Vulcain 2.1 engine, followed by over seven minutes of engine burn that covered the entire core stage flight phase, just as would happen during a real launch into space. The engine roared into action after a slight anomaly meant there was a suspenseful pause to the automated sequence, before the countdown was reset and began to tick again. The live feed continued until just after core stage operations were complete and the engine had burnt throu…

Embracing the New Space approach, it has taken just 36 months to develop and build ESA’s Arctic Weather Satellite. Now complete, this remarkable microsatellite has been shipped from OHB in Sweden to Germany where it is starting a series of tests to make sure that it will survive liftoff next year and its subsequent life in orbit.

The NASA/ESA Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighbouring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have. View the full article
