Global air pollution maps now available

A new online platform that allows for the tracking of air pollution worldwide is now available to the public. The maps, which use data from the Copernicus Sentinel-5P satellite, show the averaged nitrogen dioxide concentrations ...

The discovery of Comet SWAN by solar-watcher SOHO

Currently crossing the skies above Earth, Comet C/2020 F8 (SWAN) has the potential to become a more prominent naked eye object by late May or early June. Yet it wasn't discovered by someone looking up at the night sky. Instead, ...

Grounded aircraft could make weather forecasts less reliable

Thanks to travel restrictions and plummeting customer demand, the number of flights in the first week of April 2020 was down 61% compared with the same period in 2019. The pandemic has emptied the skies of aircraft, but it's ...

The mysterious movement of water molecules

Water is ubiquitous and essential for life. Nevertheless, experimental information about its behaviour on the atomic level—above all how it interacts with surfaces—is scarce. Thanks to a new experimental method, TU Graz ...

Water could disappear from Mars faster than expected

Mars is losing water more quickly than theory and observations would suggest. The gradual disappearance of water (H2O) occurs in the upper atmosphere of Mars as sunlight and chemistry disassociate water molecules into hydrogen ...

Water common—yet scarce—in exoplanets

The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system ...

Turbulence creates ice in clouds

Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but can now be observed for the first time in nature. This research was published by a team ...

A new satellite to understand how Earth is losing its cool

Following a rigorous selection process, ESA has selected a new satellite mission to fill in a critical missing piece of the climate jigsaw. By measuring radiation emitted by Earth into space, FORUM will provide new insight ...
