Missing the total solar eclipse on 12 August? We've got you covered. Join our live broadcast on YouTube 📺 🎤 interviews 📹 explainers 🔭 telescope feeds 🚁 drone shots 🔴 live feeds from different locations We've put together an exciting programme for you. 1/2 🔭 🧪 #EuropeanSolarEclipse

On a dark background, the Moon nearly covers the Sun, leaving only a bright crescent visible on the left-hand side. The Sun's surface looks active, with bright yellow glowing loops sticking out from it. The Sun emits a yellow-orange glow that extends around the dark Moon, and faintly lights up the Moon's left side. Craters are faintly visible on the Moon's surface. The top right has an ESA logo, and the bottom left has text reading “solar eclipse; coming to Europe

Virtual totality? ☀️ Ahead of the 12 August eclipse, KU Leuven researchers are using computer simulations and the latest solar observations from missions such as Solar Orbiter and Proba-3 to predict what the solar corona will look like. 1/2 🔭 🧪

12 August: for over one minute, day turns to night 🌑 thanks to a total solar eclipse. But will it be visible from your place? Check out these maps to find out. If you're close to the path of totality, but not within it, it is totally worth the travel! 1/2 🔭 🧪 #EuropeanSolarEclipse

Map of Earth shown as a globe, with the focus on its northern hemisphere. A red, C-shaped arc marked 'total eclipse' reaches from northeast Russia, past the North Pole, Greenland, Iceland and the Iberian Peninsula. An orange oval surrounds this arc, marked 'partial eclipse', covering most of Europe, Canada and parts of the USA, the western edge of Africa and the northeastern corner of Russia.Spain and Canary Islands map showing total solar eclipse path on 12 Aug 2026 with totality band and darkness contours

What is a solar eclipse?  The phenomenon happens when the Sun, Moon and Earth are perfectly aligned. ☀️ 🌑 🌍 The Moon blocks light from the Sun and casts a shadow on Earth. The eclipse is visible to anybody within this shadow. That's what will happen on 12 August. 1/3  🔭 🧪 #EuropeanSolarEclipse

Montage of images captured during a total solar eclipse. The images show the progression of the eclipse as the Moon moves in front of the Sun from Earth's perspective and away again. The moment where the Moon is directly in front of the Sun (centre image) is known as totality. Credit: ESA/CESAR/Wouter van Reeven.

Emoji x space 🌌 When it comes to space science, we find our way around emoji with a stretch of imagination – but wouldn't it be cool to have some more science-y ones? What space emoji would you like to have? 🔭

Infographic showing the emoji we have for black hole and spiral galaxy on the left side and the emoji we deserve on the right side. On the left side we see the literal black hole emoji and the emoji for a cyclon that looks like a blue spiral. On the right side we see a more detailed view of a black hole and its accretion disk and a spiral galaxy inspired by the Gaia Milky Way map. An ESA logo is present on the upper left corner.Infographic showing the emoji we have for a planet like Saturn and the Sun on the left side and the emoji we deserve on the right side. Here the full range of Solar System planets is visible and the Sun is more detailed with sun spots and coronal loops. An ESA logo is present on the upper left corner.Infographic showing the emoji we have for a nebula and gravitational waves on the left side and the emoji we deserve on the right side. On the left we see a nebula with stars, while on the right a more detailed view inspired by a real photo. On the left we also see the emoji for a wavy dash, while on the right we see two black holes as they spiral towards each other before merging, releasing gravitational waves – fluctuations in the fabric of spacetime. An ESA logo is present on the upper left corner.

The Sun like you've never heard it before 🎧 We sat down with ESA's Miho Janvier and Nic Bonne from the University of Portsmouth to take a sensory journey to our Sun and discover its secrets. Listen to 🎙️ 'Expendition Sound' whereever you get your podcasts 👉 https://shorturl.at/bGD5H 🔭 🧪 ☀️

A peak behind the scenes of the interview recording with Miho Janvier, for episode one of the European Space Agency’s podcast series, called ‘Expedition Sound’. It is a cheerful selfie of Miho with the podcast host Zsofi. Both are wearing headphones and have microphones before them. In the background, a roll-up banner is showing the Sun and the ESA/NASA Solar Orbiter spacecraft.A peak behind the scenes of the interview recording with Nic Bonne, for episode one of the European Space Agency’s podcast series, called ‘Expedition Sound’.

Plato meets Maxwell Our terrestrial planet hunter Plato has recently completed a series of key tests inside the Maxwell Test Chamber at ESTEC, demonstrating that its electronic equipment is fit to work in space. 🔭 🧪 1/3

Photograph of a spacecraft towering at the centre of a large test chamber. The walls and ceiling of the chamber are covered with dense rows of blue foam spikes that create a striking geometric pattern extending in all directions around the spacecraft. The right side of the spacecraft is dominated by shiny black, stowed, solar panels. The spacecraft body is partly visible on the left wrapped in reflective gold-coloured insulating foil and partially covered by a translucent protective sheet secured with small pieces of red tape.

Our Mars Express (image 1) meets NASA's Psyche (image 2) 🤝 As Psyche flew past Mars for a gravity boost on its way to an asteroid, the two missions captured exactly the same patch of the Red Planet's surface. Find out why these joint observations can be useful 👉 www.esa.int/ESA_Multimed... 🔭 🧪

This month with Mars Express, we visit one of the most ancient parts of the Red Planet, surfing over shimmering waves in the enormous Kaiser Crater. Zoom in and explore the image in more detail 👉 www.esa.int/Science_Expl... 🔭 🧪 #planetsci

Metallic waves on ancient Mars

The European Space Agency’s Mars Express has spotted a swathe of metallic-looking waves filling Mars’s large Kaiser Crater – an ancient and otherworldly dune field sculpted by wind.

🔊 What if you could listen to the Universe instead of looking at it? Enter Expedition Sound – our new podcast using sonification to explore what our missions teach us about space, guided by the expertise of scientists and vision impaired astronomers. 🔭 🧪

The key visual of the Expedition Sound podcast, which shows Our Sun in the top right corner. From there, a flowing ribbon of colourful wave-like lines travels across the dark blue, star-filled background, weaving past planets of the Solar System. The ribbon continues toward a glowing spiral galaxy in the upper left, visually linking the destinations across the Universe.
