Air pollution remains low as Europeans stay at home

Further analyses are showing the continued low levels of nitrogen dioxide concentrations across Europe – coinciding with lockdown measures implemented to stop the spread of the coronavirus. New data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus programme, show some cities seeing levels fall by 45—50% compared to the same period last year.

Earth-Size, Habitable-Zone Planet Found Hidden in Early NASA Kepler Data

While the star it orbits is much smaller than our Sun, it gets about 75% of the sunlight Earth does. NASA's Jet Propulsion Laboratory managed Kepler mission development.
