Hubble Finds Evidence of Persistent Water Vapour Atmosphere on Europa
Observations by the NASA/ESA Hubble Space Telescope recently revealed water vapour in the atmosphere of Ganymede, one of Jupiter’s moons. A new analysis of archival images and spectra has now revealed that water vapour is also present in the atmosphere of Jupiter’s icy moon Europa. The analysis found that a water vapour atmosphere is present only on one hemisphere of the moon. This result advances our understanding of the atmospheric structure of icy moons, and helps lay the groundwork for upcoming science missions which will explore Jupiter’s icy moons.

Hubble Shows Winds in Jupiter’s Great Red Spot Are Speeding Up
In Jupiter’s Great Red Spot, a storm that has been roiling for centuries, its “outer lane” is moving faster than its “inner lane” — and continues to pick up speed. By analysing long-term data from this high-speed ring, researchers have found that the wind speed has increased by up to 8 percent between 2009 and 2020. These findings could only be made with the NASA/ESA Hubble Space Telescope, which has amassed more than 10 years of regular observations, acting like a storm watcher for the planets in our Solar System.

ESA/Hubble Picture of the Week Prompts New Understanding of Einstein Ring
In December 2020 the ESA/Hubble team published a stunning view from the NASA/ESA Hubble Space Telescope of one of the most complete Einstein rings ever discovered. This observation has since been used to develop a lensing model to study the physical properties of the lensed galaxy. Scientists have successfully measured the distance to the object and determined the magnification factor to be 20, which effectively makes Hubble’s observing capability equivalent to that of a 48-metre telescope.

Hubble Discovers Hydrogen-Burning White Dwarfs Enjoying Slow Ageing
Could dying stars hold the secret to looking younger? New evidence from the NASA/ESA Hubble Space Telescope suggests that white dwarfs could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters.

Hubble Finds First Evidence of Water Vapour at Jupiter’s Moon Ganymede
Astronomers have used archival datasets from the NASA/ESA Hubble Space Telescope to reveal the first evidence for water vapour in the atmosphere of Jupiter’s moon Ganymede, the result of the thermal escape of water vapour from the moon’s icy surface.
