Webb captures stellar gymnastics in the Cartwheel Galaxy
The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of a collision between a large spiral galaxy and another smaller galaxy, not only retained a lot of its spiral character, […]
Webb reveals steamy atmosphere of distant planet in exquisite detail
Webb’s enormous mirror and precise instruments joined forces to capture the most detailed measurements of starlight filtering through the atmosphere of a planet outside our Solar System to date. The spectrum of light – which contains information about the makeup of a planetary atmosphere 1,150 light-years away – reveals the distinct signature of water. The […]

The Fingertip Galaxy: Reflecting Euclid in art
Video: 00:04:21 “After Euclid’s lifetime, it will just be floating in space. What if future beings found Euclid? How would they know anything about the humanity of the people?” – Tom Kitching, lead scientist of Euclid’s VIS instrument . The team behind ESA’s Euclid mission has come together to create something special – a personal […]

Jupiter’s moon Europa to obscure distant star
On 19 June 2022, Jupiter’s intriguing moon Europa will pass in front of a distant star, making that star appear to disappear for at least a minute. This event will be easy to see with any size of telescope from certain parts of Africa. To source
Magnetic vortices explain mysterious auroral beads
One solar stormy day in November 2018, 13 spacecraft including ESA’s Cluster mission were in the right place at the right time to spot a process that has never been seen in its entirety before. Their observations explain how vortices at the edge of Earth’s magnetosphere can cause auroral beads to dot the sky a hundred […]
Euclid gains solar power and protection
Video: 00:02:54 Spacecraft are not so different to humans – whilst the Sun can be a great source of vital energy, both people and machines must also be protected from its harmful effects. In this video, engineers at Thales Alenia Space in Turin are attaching a combined sunshield and solar panel module to the main […]
Research Fellows in space science 2022
Image: ESA has selected 9 new Fellows to pursue their own independent research in 2022. The Research Fellowships in Space Science represent one of the highlights of the ESA Science programme. Early career postdoctoral scientists are offered the unique opportunity to carry out advanced research related to the space science areas covered by ESA Science […]
MIRI and Spitzer comparison image
Image: Click here to download the gif. The James Webb Space Telescope is aligned across all four of its science instruments, as seen in a previous engineering image showing the observatory’s full field of view. Now, we take a closer look at that same image, focusing on Webb’s coldest instrument: the Mid-Infrared Instrument, or MIRI. […]
LISA mission moves to final design phase
ESA’s Laser Interferometer Space Antenna (LISA) passed an important review that marks the mission as feasible for final technology development and design before adoption. To source
Highlights from the test campaign of the Smile payload module in Europe
Video: 00:03:53 This video shows the payload module for the Solar wind Magnetosphere Ionosphere Link Explorer (Smile) undergoing a series of different environmental tests at both Airbus Madrid, Spain, and the European Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands. These milestones include integration of the Soft X-ray Imager and ultraviolet instruments on […]
