📣 Most ancient quasars ever found! @ESA_Euclid has discovered 31 ancient quasars. Two of them shone with the light of a trillion Suns back when the Universe was 670 million years old – just 5% of its current age. Discover more 👉 esa.int/Science_Exploration/…

🆕 How did this planet survive the death of its star? ☠️⭐ WD 1856 b is a Jupiter-sized exoplanet which orbits its host star (a white dwarf) extremely tightly. If it had originally been orbiting at this distance, it would have been obliterated while the star was a red giant! 🔥 1/3

A 3rd launch anniversary gift for you! 🎁 📹 In just 26 hours, @ESA_Euclid imaged millions of stars at the heart of our galaxy 🤩 Hidden among them are planets we cannot see. Yet, thanks to gravity and chance alignment, we can detect their presence. How? 👇 youtube.com/watch?v=O6S0nO1n…

New distance measurements for our galaxy 📏 @ESA_XMM & NASA's @chandraxray have measured the distance to three bright explosions echoing through the outer spiral arms of our galaxy. In doing so, they found the arms to be up to 10% further away than we thought 👉 esa.int/Science_Exploration/…

Our ESA/Hubble Picture of the Month features a starry chandelier 💡 This is the globular cluster NGC 6723, also known as the Chandelier Cluster. Each of its ‘lightbulbs’ is an individual star 27,000 light-years away in the constellation Sagittarius (the Archer) 🏹 1/3

🆕 Webb has pinpointed millions of stars in the Cigar Galaxy!  The edge-on spiral galaxy Messier 82 (M82), also known as the Cigar Galaxy is a unique sight. It is undergoing tremendous star formation (thought to be the result of a galaxy merger) for a galaxy of its size and location. 1/3

Astronomers pointed Euclid to this area to study exoplanets using a technique called microlensing. Discover how here 👉esa.int/Science_Exploration/… Thanks to these observations they will be able to confirm any exoplanet found in this region and measure its mass. 7/8
