During a break from looking at planets around other stars, ESA’s CHaracterising ExOPlanet Satellite (Cheops) mission has observed a dwarf planet in our own Solar System and made a decisive contribution to the discovery of a dense ring of material around it.

A previously unknown 100–200-metre asteroid — roughly the size of Rome’s Colosseum — has been detected by an international team of European astronomers using the NASA/ESA/CSA James Webb Space Telescope. Their project used data from the calibration of the Mid-InfraRed Instrument (MIRI), in which the team serendipitously detected an interloping asteroid. The object is likely the smallest observed to date by Webb and may be an example of an object measuring under 1 kilometer in length within the main asteroid belt, located between Mars and Jupiter. More observations are needed to better characterize this object’s nature and properties.

Mars displays fascinating geology everywhere you look – and nowhere is this more true than in the fractured, wrinkled ground seen in this image from ESA’s Mars Express.

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.

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.

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.

An ambitious new development phase of ESA’s 5G/6G Hub has begun.
