When the Moon passes between Earth and the Sun, it casts a shadow onto Earth's surface. For people in the darkest part of this shadow, the face of the Sun is totally blocked out, and its wispy atmosphere becomes visible.

On Wednesday 12 August, such a shadow will cross Greenland, Iceland, northeastern Portugal and Spain. With this being the first total eclipse visible from mainland Spain since 1905, the European Space Agency (ESA) has decided to do something special.

ESA’s live broadcast from the Observatorio Astrofísico de Javalambre will allow anyone to experience this rare phenomenon from anywhere

ESA astronaut Sophie Adenot will take part in her first-ever spacewalk during U.S. Spacewalk 97. Together with NASA astronaut Anil Menon, she will replace a Space-to-Ground antenna on the International Space Station, a critical communications system that enables high-speed data and voice links between Mission Control in Houston and the space station.

Watch it live on ESA WebTV and the ESA’s YouTube channel. Coverage begins at 13:00 CEST, with the spacewalk scheduled to begin at approximately 14:35 CEST.

Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have discovered that dust and water can form and survive surprisingly close to the supermassive black hole at the centre of our Milky Way galaxy. The observations reveal that the evolved star IRS 3 continues to enrich its surroundings with newly formed material despite the intense radiation environment around Sagittarius A*.

On 12 August 2026, parts of Europe will experience a total solar eclipse. With the Sun's bright disc covered, its surrounding atmosphere – the solar corona – will become visible to the naked eye. Unfortunately, total solar eclipses are rare and last at most a few minutes, giving scientists little time to study the Sun’s enigmatic halo.  

This is why ESA developed missions that create eclipses artificially, and why experts use computer models to create digital simulations. So how do we do it, and why is it important? 

Earth observation satellites help us monitor phenomena such as wildfires, drought and heatwaves from space. This page is updated on a regular basis with a selection of ESA’s most recent news-related images showing how the effects of climate change are impacting our world.

Observing across the starry “plains” of space, the NASA/ESA/CSA James Webb Space Telescope has taken images of NGC 2392, nicknamed the Lion Nebula.

The NASA/ESA Hubble Space Telescope previously viewed this planetary nebula in 2000, imaging the lion face-shaped target in visible light and revealing features such as the “mane” of hazy, comet-shaped objects. Now Webb has captured a clearer, more detailed view of the Lion Nebula due to its high-resolution imaging.

At first glance the nebula’s overall structure in Webb’s infrared images, both with the NIRCam (Near Infrared Camera) and MIRI (Mid-Infrared Instrument), may look quite

On 3 July 2026, an invisible signal travelled across Europe. From Oberpfaffenhofen, Germany, to Rome, Italy, the signal connected the Galileo Ground Control Centre to a Galileo Second Generation satellite for the first time, marking a major step forward in the programme’s marathon of compatibility tests.

[English] On 12 August 2026, Europe will witness one of nature’s most spectacular events: a total solar eclipse starting at 19:30 CEST.

As the Moon’s shadow sweeps across Spain, join the European Space Agency live from Observatorio Astrofísico de Javalambre where Dame Dr. Maggie Aderin and ESA scientists will fill you in on everything you need to know about the eclipse and reveal the science behind the spectacle.
