Video: 00:03:31 ESA’s Euclid mission will create a 3D-map of the Universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast amount of data, it will cover more than a third of the sky and its third dimension will represent time spanning 10 billion years of cosmic history. But dealing with the huge and detailed set of novel data that Euclid observations will produce is not an easy task. To prepare for this, scientists in the Euclid Consortium have developed one of the most accurate and comprehensive computer simulations of the large-scale structure of…

According to the World Meteorological Organization, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region. View the full article

Video: 00:02:01 In July 2023 local time, the last Ariane 5 blasted off from Europe’s Spaceport in French Guiana. Relive the moment from up close in this 360° video showing the liftoff and Ariane 5 soaring to orbit. The audio comes from the camera itself that was clamped to a steel cable on a northern ramp surrounding the Ariane 5 flame trench – about 50 m from the ZL3 launchpad. Despite being so close the camera was only protected against the humidity and rain in French Guiana. A solar panel provided extra power to the camera as it had to record for long time to capture the liftoff – no people are allowed so close to the launchpad during the countdown and blastoff…

Video: 00:04:59 The 117th and final launch of Europe’s Ariane 5 rocket capped a series which began in 1996. Commercial, institutional and scientific payloads included such iconic missions as Rosetta, the James Webb Space Telescope and Juice. Seen here is the launch campaign for VA261 on 5 July 2023, to close the Ariane 5 book; onboard were German aerospace agency DLR’s Heinrich Hertz experimental communications satellite and French communications satellite Syracuse 4b.

In recent weeks, devastating wildfires have spread in Greece, Italy, Spain, Portugal, Algeria, Tunisia and Canada, causing human casualties as well as massive environmental and economic damage. While wildfires are a natural part of many ecosystems, scientists have warned that they are becoming more frequent and more widespread. In response, an upgraded version of ESA’s World Fire Atlas is now available providing a detailed analysis of wildfires across the globe. View the full article

Video: 00:01:35 Aeolus’s mission is over, but weather forecasting is improved forever, and a new precedent has been set for safe satellite reentries. The trailblazing Earth Explorer returned through our atmosphere on 28 July, following the path it was guided on by ESA’s mission control over Earth’s most uninhabited regions, finally disintegrating over the Antarctic. A week-long series of manoeuvres led to this point. They had never been performed before and pushed the satellite to its limits. Aeolus was never designed to fly at such low altitudes – its thrusters and fuel reserves were not made to operate in the thick lower reaches of Earth’s atmosphere. Despite …

Image: This image shows the irregular galaxy NGC 6822, which was observed by the Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI) mounted on the NASA/ESA/CSA James Webb Space Telescope. As their names suggest, NIRCam and MIRI probe different parts of the electromagnetic spectrum. This allows the instruments to observe different components of the same galaxy, with MIRI especially sensitive to its gas-rich regions (the yellow swirls in this image) and NIRCam suitable for observing its densely packed field of stars. NGC 6822 lies about 1.5 million light-years away, and is the Milky Way’s nearest galactic neighbour that is not one of its satellites. It has …

Surpassing scientific expectations and exceeding its planned life in orbit, the Aeolus wind mission has been hailed as one of ESA’s most successful Earth observation missions. And now, its end will go down in history too, thanks to the ingenuity of the Agency’s mission control team who guided this remarkable satellite down to Earth’s atmosphere for a safe reentry.

Video: 00:01:47 In the month after its launch on 1 July, Euclid has travelled 1.5 million kilometres from Earth towards the Sun-Earth Lagrange point L2, meaning it has ‘arrived’ at its destination orbit. This animation showcases the orbits of Euclid (green), the James Webb Space Telescope (blue), and the Gaia mission (yellow) around this unique position in space. The positions of the spacecraft in this animation don’t correspond to their current positions in space. Located about 1.5 million kilometres from Earth in the opposite direction from the Sun, L2 is about four times further away than our Moon. Several other space missions like Webb and Gaia also orbit L2 a…
