Jupiter and its moon Europa

On 25 August 2020, NASA/ESA’s Hubble Space Telescope conducted its annual check-up on Jupiter leading astronomers to try and understand how the planet’s turbulent atmosphere shifts and changes. In the same image is the gas giant’s moon Europa but the interesting detail here is the bright-white storm that’s travelling at 560 kilometres (350 miles) per hour at the mid-northern latitudes. Erupting on 18 August 2020, weather systems like this usually only pop up once every six years but this specimen offers the chance to study a young and evolving Jovian storm.
