Video: 00:04:07 Clouds are one of the biggest mysteries in the climate system. They play a key role in the regulating the temperature of our atmosphere. But we don’t know how their behaviour will change over time as Earth’s atmosphere gets warmer. This is where EarthCARE comes in. Launching on 28 May 2024, ESA’s Earth Cloud, Aerosol and Radiation Explorer will help quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere. With its suite of four cutting-edge instruments, EarthCARE is a groundbreaking advancement in satellite technology. It promises to deliver unprecedented data – unravelling the complexities of both clouds and aeros…

Spacemanic, a Slovak and Czech startup company, won this year’s Prix Bulles Cardin award of €20 000 on 17 May for its ocean WaterCube. This device, which is based on space hardware, has sensors which measure pollution levels in sea water allowing the identification of pollution hotspots. With this data, action can be taken to safeguard habitats and species critical for the long-term sustainability of marine ecosystems and fisheries. View the full article

Video: 00:51:05 ESA’s Earth Cloud Aerosol and Radiation Explorer (EarthCARE) mission is designed to advance our understanding of the role that clouds and aerosols play in reflecting incident solar radiation back out to space and trapping infrared radiation emitted from Earth’s surface. Developed as a cooperation between ESA and the Japan Aerospace Exploration Agency (JAXA), this exciting mission will make a range of different measurements that together will shed new light on the role that clouds and aerosols play in regulating Earth’s delicate temperature balance. With global climate change increasingly affecting our planet, EarthCARE is poised to provide data fo…

In the run up to April’s total solar eclipse, ESA-led Solar Orbiter and NASA-led Parker Solar Probe are both at their closest approach to the Sun. They are taking the opportunity to join hands in studying the driving rain of plasma that streams from the Sun, fills the Solar System, and causes dazzlement and destruction at Earth.

ESA’s gamma-ray space telescope Integral has played a decisive role in capturing jets of matter being expelled into space at one-third the speed of light. The material and energy were liberated when huge explosions occurred on the surface of a neutron star. This world-first observation proved to be “a perfect experiment” for exploring astrophysical jets of all descriptions. View the full article

Image: A citizen scientist digging through data from the ESA/NASA Solar and Heliospheric Observatory has found the mission’s 5000th comet. The tiny comet – indicated between the vertical lines in the inset – belongs to the ‘Marsden group’, named after the British astronomer Brian Marsden, who first recognised the group based on SOHO observations. Marsden group comets are thought to be pieces shed by the much bigger Comet 96P/Machholz, which SOHO observes as it passes close to the Sun every 5.3 years. This 5000th comet was discovered by Hanjie Tan, an astronomy PhD student in Prague, Czechia. Hanjie has been comet hunting since he was just 13 years old, discovering over…

When it comes to predicting what our climate will be like in the future, vegetation matters. Plants and trees exert a powerful influence over both the energy cycle and the water cycle. And, crucially, it is estimated that vegetation draws down well over three billion tonnes of carbon from the atmosphere each year – this is equivalent to a third of greenhouse-gas emissions from human activity. Accounting for vegetation growth is clearly important in the complex climate puzzle – and the release of a new satellite dataset is set to help climate modellers with the challenge of evaluating the impacts of climate change.
