The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of a collision between a large spiral galaxy and another smaller galaxy, not only retained a lot of its spiral character, but has also experienced massive changes throughout its structure. Webb’s high-precision instruments resolved individual stars and star-forming regions within the Cartwheel, and revealed the behaviour of the black hole within its galactic centre. These new details provide a renewed understanding of a galaxy in the midst of a slow transformation. Vi…

Utah’s Great Salt Lake dropped to its lowest recorded water level last month as a megadrought persists across the US southwest, forcing the fast-growing city to curb its water use. From space, satellite images show how water levels have fallen from 1985 to 2022 – exposing large expanses of lakebed. View the full article

In just a few months’ time Europe’s first Meteosat Third Generation satellite will soar into the skies on an Ariane 5 rocket from French Guiana. From geostationary orbit, this new satellite, carrying two new highly sensitive instruments, will take weather forecasting to the next level. Taking a significant step towards launch, the satellite operations teams at two different centres have completed an all-important suite of tests ensuring that their procedures are fully compatible with the satellite.

ESA’s EnVision mission to Venus will perform optical, spectral and radar mapping of Earth’s sister planet. But before getting down to work the van-sized spacecraft needs to ‘aerobrake’ – lowering its orbit with thousands of passages through the planet’s hot, thick atmosphere for up to two years. A unique ESA facility is currently testing candidate spacecraft materials to check they can safely withstand this challenging process of atmospheric surfing. View the full article

Any movement beneath our feet – from barely perceptible subsidence to the sudden appearance of a sinkhole or a crashing landslide – spells big trouble. Even relatively modest subsidence can weaken buildings and infrastructure and lead to issues such as flooding, and at worst the abrupt disappearance of sections of land brings immediate threat to life. Monitoring and predicting our shifting land is clearly essential for adopting mitigating strategies. And now, thanks to Europe’s environmental Copernicus programme and the Sentinel-1 radar satellite mission, the first Europe-wide subsidence and soil movement analysis service is available to the public.

ESA’s upcoming EarthCARE satellite mission has just taken a big stretch. Engineers have gently unfolded this new satellite’s huge five-panel solar wing to test that it will deploy correctly once it is in space. The solar wing is a critical part of the satellite, providing the energy for EarthCARE to do its job: to quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere.
