The James Webb Space Telescope captured its first images and spectra of Mars on 5 September 2022. The telescope, an international collaboration between NASA, ESA and the Canadian Space Agency, provides a unique perspective with its infrared sensitivity on our neighbouring planet, complementing data being collected by orbiters, rovers, and other telescopes.

The ozone layer in our upper atmosphere protects Earth from the harmful effects of ultraviolet radiation. The use of human-produced chemicals in our atmosphere used for many years depleted Earth’s ozone layer. However, the reduction in the consumption of ozone-depleting substances driven by the Montreal Protocol – an international treaty designed to protect the ozone layer – has allowed for the ozone hole to slowly recover. This global agreement demonstrates the power of international commitment and immediate global action in protecting our environment. ESA has been involved in monitoring the ozone for over two decades. Today, 16 September, marks the International Day for…

This summer, heatwaves struck Europe, North Africa, the US and Asia with temperatures reaching over 40°C in places – breaking many long-standing records. Images from the Copernicus Sentinel-3 mission show the scale of Britain’s heatwave as it baked in extreme temperatures in August. View the full article

Video: 01:04:23 On September 27 at 01:14 CEST, NASA’s DART (for ‘Double Asteroid Redirection Test’) mission is lined up to collide with a body called Dimorphos – a 160-m diameter ‘moonlet’ of a larger asteroid called Didymos – to try and measurably shift its orbit. In this media briefing, hear more about Europe’s contribution to the DART mission, and learn of ESA’s own mission with a close-up survey of Dimorphos, conducted by a spacecraft called HERA. The HERA mission is planned for launch in 2024. View the full article

Video: 00:19:25 On 15 September 2022, ESA astronaut Samantha Cristoforetti conducted an in-flight call with the European Parliament from the International Space Station. In conversation with President Metsola and ESA Director General Josef Aschbacher, she provided insights into the importance Europe’s presence in space, as well as the scientific and technological progress enabled by its activities. The three also touched on Samantha’s upcoming commandership, life on the Station, and the pressing issue of space debris. View the full article

Since it was launched more than 12 years ago, ESA’s CryoSat ice mission has dazzled by way of its sheer technological and scientific excellence. This superb Earth Explorer satellite has returned a wealth of information that has transformed our understanding of Earth’s ice and how it is responding to climate change. In some circumstances, however, being dazzled isn’t a good thing, particularly when it comes to measuring the height of sea ice from space during the summer. A paper published in Nature describes how scientists have now found an ingenious way of removing the pesky problem of dazzle from surface meltwater to yield the first ever continuous, year-round, altimetry…

Image: ESA astronaut Alexander Gerst and NASA astronaut Stephanie Wilson are getting world-class geology training this week during the fifth edition of ESA’s Pangaea course. A balanced mix of theory and field trips, the course will take the pair all over Europe to hone their geology skills. The training began last week in the Italian Dolomites with lessons on fundamental geology knowledge and skills, martian geology and asteroids at Bletterbach Canyon. The rock samples from the canyon Alexander is holding in this image are a combination of gypsum (white hue) in siltstone-sandstone (reddish hue), and are analogous to rocks found on Mars. This week, Alexander and Stephan…

With data from its closest pass of the Sun yet, the ESA/NASA Solar Orbiter spacecraft has found compelling clues as to the origin of magnetic switchbacks, and points towards how their physical formation mechanism might help accelerate the solar wind. View the full article

Video: 00:00:58 ESA’s Solar Orbiter has solved the mystery of a magnetic phenomenon in the solar wind. It has taken the first ever image of a ‘switchback’ in the solar corona, confirming its predicted ‘S’ shape. A switchback is defined by rapid flips in magnetic field direction. The observed switchback is linked to an active region associated with sunspots and magnetic activity where there is an interaction between open and closed magnetic field lines. The interaction releases energy and sends the S-shaped disturbance into space. The new data suggest that switchbacks could originate near the solar surface, and may be important in understanding the acceleration and…

Video: 00:03:57 It has been an exciting and busy summer for the European Space Agency, with development and testing of its new Ariane 6 launcher. At Europe’s spaceport in, French Guiana, a test model of the launcher’s central core was assembled for the first time. Ariane 6 is the first Ariane rocket to be assembled horizontally, which is simpler and less costly than more traditional vertical assembly. Then, the rocket was moved to its launchpad and placed upright in the massive mobile gantry for combined tests, to validate the compatibility between all components of the complete launch system. Soon more testing will be done on Ariane 6’s upper stage at a purpose-b…

Image: Astronomers have been bemused to find young stars spiralling into the centre of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. The outer arm of the spiral in this huge, oddly shaped stellar nursery – called NGC 346 – may be feeding star formation in a river-like motion of gas and stars. This is an efficient way to fuel star birth, researchers say. The Small Magellanic Cloud has a simpler chemical composition than the Milky Way, making it similar to the galaxies found in the younger Universe, when heavier elements were more scarce. Because of this, the stars in the Small Magellanic Cloud burn hotter and so run out o…

Video: 00:01:00 This video takes the viewer on a journey that zooms through space to reveal the Tarantula Nebula. Thousands of never-before-seen young stars are spotted in the stellar nursery called 30 Doradus, captured by the NASA/ESA/CSA James Webb Space Telescope. It is nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favourite for astronomers studying star formation. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust. Read more.
