Dropcoal, short for Drop Coalescence, is a research project that studies how droplets form in space and on Earth. The results will grant insights into raindrop and cloud formation, fuel combustion and interactions between materials, all with broad implications for industry and academy. They also play a crucial role in administering medicine to astronauts during lengthy and far-reaching space missions.

The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/ESA/CSA James Webb Space Telescope. Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image. This galactic portrait is a composite image that integrates data from Webb’s Near-InfraRed Camera (NIRCam) and the innovative Mid-InfraRed Instrument (MIRI), half of which was contributed by Europe.

On 26 August 2023, at 09:27 CEST (08:27 BST), Crew-7 aboard the Crew Dragon spacecraft Endurance embarked on a journey to the International Space Station. Watch the full coverage of their launch from pad 39A at Kennedy Space Center in Florida, USA.
The ESA/NASA Solar Orbiter spacecraft has discovered a multitude of tiny jets of material escaping from the Sun’s outer atmosphere. Each jet lasts between 20 and 100 seconds, and expels plasma at around 100 km/s. These jets could be the long-sought-after source of the solar wind.
Confirmed by the World Meteorological Organization, July 2023 was the hottest month on record, with high-impact weather continuing through August. These records are based on air temperatures, but measurements of the temperature of Earth’s surface taken from space are also essential to tracking the impact of climate change, and to being better prepared for such extremes – especially when it comes to cities where stifling urban heat islands form.
Image: A month after fires ravaged the island of Rhodes in July 2023, more fires have ripped through Greece this week as southern Europe swelters under a late summer heatwave. This Copernicus Sentinel-2 image shows the ongoing blaze near Alexandroupoli in the Evros region of northeast Greece – close to the Türkiye border.
Hera is complete. ESA’s asteroid mission for planetary defence was built and prepared in two halves, but now, through a painstaking operation, they have been mated together to make a single spacecraft, ready for full-scale testing of its readiness for space.
ESA’s Mars Express has turned its trusty High Resolution Stereo Camera (HRSC) towards Mars’s most imposing volcano, revealing its dramatic surroundings and turbulent past.

Crew-7 has arrived at NASA’s Kennedy Space Center in Florida, USA, in the run-up to the International Space Station launch.
The NASA/ESA/CSA James Webb Space Telescope has observed the well-known Ring Nebula with unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring Nebula is an archetypal planetary nebula. The object is also known as M57 and NGC 6720, and is relatively close to Earth at roughly 2,500 light-years away.
The X-Ray Imaging and Spectroscopy Mission (XRISM) is ready to launch on 26 August 2023 to observe the most energetic objects and events in the cosmos. In doing so, it will unveil the evolution of the Universe and the structure of spacetime.
