A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

Video: 00:00:14 In a significant leap forward for meteorology, the preliminary data obtained by Meteosat Third Generation’s two instruments, the Flexible Combined Imager (FCI) and the Lightning Imager (LI), were successfully combined today for the first time – highlighting their complementary capabilities. This first set of animations gives us a preview of the system’s future impact. This animation shows the combined observations from the Meteosat Third Generation’s instruments starting at 12:00 UTC on 03 June 2023 and ending at 12:00 UTC of 04 June 2023. Lightning activity is more intense over central Africa, the northern part of South America, Europe and the Mid…

Scientists have used Solar Orbiter’s EUI camera in a new mode of operation to record part of the Sun’s atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation was made possible with a last-minute ‘hack’ to the camera and will almost certainly influence new solar instruments for future missions. View the full article

Video: 00:01:07 On 5 September 2023, teams from France’s space agency CNES and Arianegroup under the lead of ESA carried out a complete Ariane 6 launch sequence on its launch pad at Europe’s spaceport in French Guiana. The test ended with a hot-fire of the launcher’s core stage and startup of the Vulcain 2.1 engine. This is a key step in the test campaign. It follows from initial integration of the Ariane 6 launcher on its launch pad, electrical and fluid system tests and the first launch sequence test run on 18 July 2023. This test involved a launch sequence and final countdown representative of a launch, including removal of the Ariane 6 mobile gantry and fillin…

Video: 00:01:01 On 1 September 2023 ESA’s all-new Ariane 6 launch vehicle fired its two upper stage engines to simulate the way they will have to operate together at German aerospace agency DLR’s engine test centre in Lampoldshausen, Germany. The test – of the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench. Vinci, the upper stage engine of Ariane 6 fed by liquid hydrogen and oxygen, can be stopped and restarted multiple times – to place satellites into different orbits and then de-orbit the upper stage, so it is not left behind as hazardous debris in space. The APU makes it possible for Vinci to restart in spa…
