New biomass map to take stock of the world's carbon

The first of a series of global maps aimed at quantifying change in carbon stored as biomass across the world's forests and shrublands has been released today by ESA's Climate Change Initiative at COP25—the United Nation ...

French earthquake fault mapped

This week, southeast France was hit by a magnitude 5 earthquake with tremors felt between Lyon and Montélimar. The Copernicus Sentinel-1 radar mission has been used to map the way the ground shifted as a result of the quake.

The rotation of Venus

Venus is covered in a thick layer of clouds, one reason that it appears so bright in the sky. Ancient astronomers had a good idea of what (since Copernicus) we know as its orbital period; the modern measurement is that Venus ...

'Snow-cannon' Enceladus shines up Saturn's super-reflector moons

Radar observations of Saturn's moons, Mimas, Enceladus and Tethys, show that Enceladus is acting as a "snow-cannon," coating itself and its neighbors with fresh water-ice particles to make them dazzlingly reflective. The ...

Scientists planning now for asteroid flyby a decade away

On April 13, 2029, a speck of light will streak across the sky, getting brighter and faster. At one point it will travel more than the width of the full Moon within a minute and it will get as bright as the stars in the Little ...

Three Earth Explorer ideas selected

As part of ESA's continuing commitment to realise cutting-edge satellite missions to advance scientific understanding of our planet and to show how new technologies can be used in space, three new ideas have been chosen to ...

Observatories team up to reveal rare double asteroid

New observations by three of the world's largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other.

Radar satellites able to measure water stress in trees

Radar technology in space can be used to measure how 'thirsty' plants and crops are. This could play a key role in improving our understanding of how ecosystems and the water and carbon cycles interrelate. In theory, we have ...
