Webb spots quartz crystals in clouds of exoplanet WASP-17b

Image: This is a transmission spectrum of the hot gas giant exoplanet WASP-17 b captured by the NASA/ESA/CSA James Webb Space Telescope’s innovative Mid-Infrared Instrument (MIRI) on 12–13 March 2023. It reveals the first evidence for quartz (crystalline silica, SiO2) in the clouds of an exoplanet. This marks the first time that SiO2 has been identified in an […]

Camera ‘hack’ lets Solar Orbiter peer deeper into Sun’s atmosphere

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 […]

Earendel and the Sunrise Arc in the galaxy cluster WHL0137-08

Image: This image from the NASA/ESA/CSA James Webb Space Telescope shows a massive galaxy cluster called WHL0137-08, and at the right, an inset of the most strongly magnified galaxy known in the Universe’s first billion years: the Sunrise Arc. Within that galaxy is the most distant star ever detected, first discovered by the NASA/ESA Hubble […]

Plato’s structural test campaign

From May to August 2023 a structural model of ESA’s next exoplanet mission, Plato, is undergoing a test campaign at ESA’s ESTEC Test Centre, at Noordwijk in the Netherlands. Plato is planned to launch on an Ariane 6 in 2026. During lift-off Plato will have to withstand intense vibrations and immense blasts of noise. To […]
