Image: A crowded field of galaxies throngs this Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope, along with bright stars crowned with Webb’s signature six-pointed diffraction spikes. The large spiral galaxy at the base of this image is accompanied by a profusion of smaller, more distant galaxies which range from fully-fledged spirals to mere bright smudges. Named LEDA 2046648, it is situated a little over a billion light-years from Earth, in the constellation Hercules. One of Webb’s principle science goals is to observe distant — and hence ancient — galaxies to understand the details of their formation, evolution, and composition. Webb’s keen infr…

Video: 00:04:25 An iceberg around the size of Greater London broke off Antarctica’s Brunt Ice Shelf due to a natural process called ‘calving’. The iceberg, measuring 1550 sq km, detached from the 150 m-thick ice shelf a decade after scientists first spotted massive cracks in the shelf. For more information on the newly-birthed A81 iceberg, click here. View the full article

We’ve just made it easier to use the ESA brand to create merchandise or materials for events. If you are interested in producing and selling merchandising that shows the ESA logo, the ESA flags patch or ESA’s mission patches, there is now a simple way to request the use of ESA emblems.

Video: 00:00:23 Using radar images from the Copernicus Sentinel-1 mission, the animation shows the A81 iceberg breaking away from the Brunt Ice Shelf on 25 January 2023. The new berg is estimated to be around 1550 sq km, which is around the size of Greater London, and is approximately 150 m thick. It calved when the crack known as Chasm-1 split northwards severing the west part of the ice shelf. The white square indicated the final breakpoint near the McDonald Ice Rumples. Routine monitoring from satellites offers unparalleled views of events happening in remote regions. The Copernicus Sentinel-1 mission carries radar, which can return images regardless of day or …

Video: 00:01:07 The mission to return martian samples back to Earth will see a European 2.5 metre-long robotic arm pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery. The sophisticated robot, known as the Sample Transfer Arm or STA, will play a crucial role in the success of the Mars Sample Return campaign. The Sample Transfer Arm is conceived to be autonomous, highly reliable and robust. The robot can perform a large range of movements with seven degrees of freedom, assisted by two cameras and a myriad of sensors. It features a gripper – akin to a hand – that can capture and handle the sample tu…

Satellite imagery confirms an enormous iceberg, around five times the size of Malta, has finally calved from Antarctica’s Brunt Ice Shelf. The new berg, estimated to be around 1550 sq km and around 150 m thick, calved when the crack known as Chasm-1 fully extended northwards severing the west part of the ice shelf. This crack was first revealed to be extending in early 2012 after having been dormant for some decades. After several years of desperately clinging on, image data from the Copernicus Sentinel missions visually confirm the calving event. View the full article

Galileo’s capabilities have grown with the addition of a new High Accuracy Service, freely available worldwide to anyone with a suitably equipped receiver. Delivering horizontal accuracy down to 20 cm and vertical accuracy of 40 cm, the High Accuracy Service is enabled through an additional level of real-time positioning corrections, delivered through a new data stream within the existing Galileo signal.

Video: 00:00:30 This video features a new image from the NASA/ESA/CSA James Webb Space Telescope’s Near-InfraRed Camera (NIRCam), showcasing the low-mass star forming region Chameleon I. An international team of astronomers has reported the discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date by studying this region. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life. This research forms part of the Ice Age project, one o…

With diminishing ice one of the biggest casualties of our warming world, it’s imperative that accurate measurements continue to be made for scientific research and climate policy, as well as for practical applications such as ship routing. To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.

One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga, spewing volcanic material up to 58 km into the atmosphere. It brought a nearly 15 m tsunami that crashed ashore, destroying villages, and creating a sonic boom that rippled around the world – twice. Satellites orbiting Earth scrambled to capture images and data of the aftermath of the disaster. Almost a year later, you can now listen to a sonification of the largest eruption of the 21st Century, created using wind data from ESA’s Aeolus mission. View the full article
