“Intellectual growth should commence at birth and cease only at death.” — Albert Einstein, Out of My Later Years

“A man's ethical behaviour should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.” ― Albert Einstein

A smooth galaxy, observed with the Hubble Space Telescope in the COSMOS survey. It is at redshift 0.57 (lookback time 5.70 billion years) with coordinates (149.99418, 1.77989). 50 volunteers classified this galaxy in Galaxy Zoo: Hubble.

Hubble went back to observe interstellar comet #3I/ATLAS on 30 November. At the time, the comet was about 286 million kilometres from Earth 👉 www.esa.int/ESA_Multimed... Hubble tracked the comet as it moved across the sky. That's why background stars appear as streaks of light. 🔭 🧪

Mission confirmed ✅ #CopernicusEU Sentinel-6B is now in orbit and ready to begin its Launch & Early Operations phase with @operations.esa.int. The satellite is ready to continue a decades-long mission to track the height of the planet’s seas – a key measure of climate change.

Hubble has returned to the ‘Lost Galaxy’, a spiral galaxy about 50 million light-years away in the constellation Virgo. Its nickname comes from the fact that it’s extremely faint when viewed through a small telescope. Not the case for Hubble though! Read more 👉 esahubble.org/images/potw2... 🔭

🚀It’s almost time to shape the next chapter of Europe’s journey in space. The European Space Agency’s Council Meeting at Ministerial Level, known as #CM25, will take place in Bremen, Germany, on 26 and 27 November 2025. Journalists register here 👉 www.esa.int/Newsroom/Pre...

We’re seeing double: two interacting galaxies imaged by #Hubble and #NASAWebb. Hubble shows obscuring brown dust and blue star-filled regions, while Webb shows glowing cold dust as white material and pink stars still embedded in dust: https://bit.ly/3F72M4a 🔭 🧪

🌍 Iron-rich red soils and parallel sand dune ridges stand out in this Φsat-2 image of the Gibson Desert. Spanning over 150 000 sq km, the desert’s landscape is shaped by wind and a dry climate. In the lower part of the image, the dry lakebed of the Fortescue River is visible.

Venus is a Solar System enigma. Although Venus is similar in size and distance from the Sun to Earth, it has evolved very differently from our planet. Our #Envision mission will aim to solve some of the puzzle by thoroughly studying our closest neighbour. www.esa.int/Science_Expl... 🔭

Here’s an obvious one that I’ve never imaged before. This is Messier 17, the Swan or Omega Nebula, another brilliant star factory located in the constellation Sagittarius. It’s nice to be outside again but the nights seem too short this time of year. 🔭 #astrophotography

Totalling around 120 hours of observing time, this is the longest the NASA/ESA/CSA James Webb Space Telescope has ever focused on a single target. The deep field aims to probe the Cosmic Dawn, when the Universe was only a few million years old. Read more 👉 www.esa.int/ESA_Multimed... 🔭 🧪 ☄️

Ridin' solo 💫 A single member of a galaxy pair takes centre stage in this NASA/ESA Hubble image. The galaxy NGC 3507 is classified as a barred spiral because the galaxy’s sweeping spiral arms emerge from the ends of a central bar of stars rather than the central point of the galaxy.

You're an interesting species. An interesting mix. You're capable of such beautiful dreams, and such horrible nightmares. You feel so lost, so cut off, so alone, only you're not. See, in all our searching, the only thing we've found that makes the emptiness bearable, is each other.

Why do we know so little about Mercury? 🤔 It mostly comes down to the planet's proximity to the Sun. This makes Mercury more difficult to observe, harder to reach and too hot to orbit up close. But our #BepiColombo mission is ready for the challenge. Read more 👉 www.esa.int/Science_Expl... 🔭 🧪
