New research reveals that dust carried by the wind from southern Africa towards Madagascar triggered the largest phytoplankton bloom in two decades – and, unusually, this occurred at a time of year when such blooms are rarely seen. To source

ESA releases new strategy for Earth observation
ESA has released its new Earth Observation Science Strategy, Earth Science in Action for Tomorrow’s World. Responding to the escalating threats from climate change, biodiversity loss, pollution and extreme weather and the need to take action to address these threats, this forward-looking strategy outlines a bold vision for Earth science through to 2040.

The journey of Juice – episode 1
Video: 00:20:48 ESA’s Jupiter Icy Moons Explorer (Juice ), is on an epic eight-year journey to Jupiter. This first episode of ‘The journey of Juice’ tells the story of Juice’s first months in space, from its launch on 14 April 2023 to its lunar-Earth gravity assist (LEGA for short) in August 2024. This flyby was […]

Sentinel-2C captures stunning glimpse of the Moon
Image: On 20 September, the Copernicus Sentinel-2C satellite captured its first stunning image of the Moon, achieved by rolling the satellite sideways in a unique manoeuvre. Although Sentinel-2C is primarily designed for Earth observation, this image – intended for calibration and cross-mission comparisons – exceeded expectations. To source
Hubble sees black hole beam boosting stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but apparently in a dangerous neighbourhood nearby. […]
Turbulence in the Sun’s corona
Video: 00:00:29 Solar wind is a never-ending stream of charged particles coming from the Sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the Sun’s variable magnetic field, creating chaotic and fluctuating motion known as turbulence. This video confirms something long suspected: the […]
Webb finds potential missing link to first stars
Looking deep into the early Universe with the NASA/ESA/CSA James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. To source
Draco mission made for destruction
Over the nearly 70 years of spaceflight, about 10 000 intact satellites and rocket bodies have reentered the atmosphere with many more to follow. Yet for such a ubiquitous event, we still lack a clear view on what actually happens to a satellite during its fiery last moments. ESA is preparing the Destructive Reentry Assessment […]
