The NASA/ESA Hubble Space Telescope's Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away.
22 August 2019As part of preparations for the launch of ESA's Jupiter Icy Moons Explorer, its navigation camera has been given a unique test: imaging its destination from Earth.
8 August 2019The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter’s clouds in this new image taken on 27 June 2019. It features the planet’s trademark Great Red Spot and a more intense colour palette in the clouds swirling in the planet’s turbulent atmosphere than seen in previous years.
25 July 2019On 31 March 2017, Jupiter's moon Europa passed in front of a background star – a rare event that was captured for the first time by ground-based telescopes thanks to data provided by ESA's Gaia spacecraft.
27 August 2019The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth's magnetosphere, to pave the way for this pioneering venture.
13 May 2019One has a thick poisonous atmosphere, one has hardly any atmosphere at all, and one is just right for life to flourish – but it wasn't always that way. The atmospheres of our two neighbours Venus and Mars can teach us a lot about the past and future scenarios for our own planet.
2 August 2019Like most spacecraft, ESA's Solar Orbiter carries a number of deployable structures that play key roles in the success of its mission. Earlier this year, engineers completed a series of deployment tests on the spacecraft's antennas, instrument boom and solar arrays.
17 October 2018For the CHEOPS mission, September was a busy month of acoustic noise testing and Electromagnetic Compatibility (EMC) testing at ESA's technical centre in the Netherlands.
