Image: Strange times meet strange clouds. Noctilucent or ‘night shining’ clouds (NLC) are captured over Knowlton Church in Dorset, UK, by astrophotographer Ollie Taylor in the early hours of 22 June. A summer phenomenon, these rare clouds are visible when the Sun is below the viewer’s horizon, shining light on these tenuous wisps. First mentioned […]

Adding microscopic nano-materials to carbon fibre composites has resulted in stronger, tougher fins for divers. A space material company teamed up with a market leader in the design and production of free-diving and spear-fishing equipment through ESA’s Technology Transfer and Patent Office . To source

Video: 00:02:40 This movie was created using an image mosaic  made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express, which was first published in December 2018. The mosaic combines data from the HRSC nadir and colour channels; the nadir channel is aligned perpendicular to the surface of Mars, as […]

We speak to an astronomer who spends his day studying the motions of ancient asteroids as they roam around the Solar System. If one of them poses a threat, he’ll be one of the first to know, and would provide us with the information we would need to act. Podcast: Exploring risky asteroids with Astronomer […]

ESA’s Gaia space observatory is an ambitious mission to construct a three-dimensional map of our galaxy by making high-precision measurements of over one billion stars. However, on its journey to map distant suns, Gaia is revolutionising a field much closer to home. By accurately mapping the stars, it is helping researchers track down lost asteroids. […]

Concentrations of sulphur dioxide in polluted areas in India have decreased by around 40% between April 2019 and April 2020. Using data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, scientists have produced new maps which show the drop in concentrations across the country in times of COVID-19.
