Hubble Time! 🌌⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ UGC 695 is a low-surface-brightness (LSB) galaxy. These galaxies are so faint that their brightness is less than the background brightness of Earth’s atmosphere, which makes them tricky to observe. This low brightness is the result of the relatively small number of stars within them — most of the baryonic matter in these galaxies exists in the form of huge clouds of gas and dust. The stars are also distributed over a relatively large area. ⠀⠀⠀⠀⠀⠀ LSB galaxies, like dwarf galaxies, have a high fraction of dark matter relative to the number of stars they contain. Astronomers still debate about how LSB galaxies formed in the first place. ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀ Go to our @instagram Story to learn more about this image.⠀⠀⠀ ⠀⠀⠀⠀⠀⠀ 📸 @europeanspaceagency/@hubbleesa & @NASA, D.

Will we learn more with Cheops⁉️ 🤩 ⠀⠀⠀ With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth within the habitable zone by @ucl researchers in a world first. K2-18b, which is eight times the mass of Earth, is now the only planet orbiting a star outside the Solar System, or exoplanet, known to have both water and temperatures that could support life. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 🖥 @europeanspaceagency /@hubbleesa, M.

Slovenia

We are going down‼️ ⠀⠀⠀ Six astronauts, five space agencies and a fresh start into underground worlds to help prepare for living on other planets. Our latest training adventure will equip an international crew with skills to explore uncharted terrains on the Moon and Mars, this time with a focus on the search for water. ⠀⠀⠀ The CAVES training course takes astronauts to the depths of Earth to improve their communication, problem-solving and teamwork skills. ⠀⠀⠀ The six cavenauts of this edition of CAVES are our astronaut @astro_alex_esa, @NASA astronauts Joe Acaba and Jeanette Epps, @roscosmosofficial’ cosmonaut @spacelegion, @canadianspaceagency astronaut @astro_kutryk and @jaxajp Takuya Onishi. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 @europeanspaceagency@alessioromeo71

Strait of Gibraltar

Almost there 👉 💧 👈 ⠀⠀⠀ This tiny strip water captured by Luca Parmitano from the @iss, is all that separates the African continent from the Eurasian one. ⠀⠀⠀ When Luca posted this image of the Strait of Gibraltar on his Twitter account, he said: "Where two continents, two histories, meet and currents play with water and air creating pictograms of clouds and sea." ⠀⠀⠀ 📸 @europeanspaceagency / @NASA - L.Parmitano ⠀⠀⠀ ⠀⠀⠀

Mexicali, Baja California

All these trippy colours have a meaning! @esa_earth ・・・ Today, the Copernicus Sentinel-1 mission takes us just south of the US border, to the region of Baja California in northwest Mexico. Its capital city, Mexicali, is visible top left of the image. This false colour image contains three separate images overlaid on top of each other. Captured on 30 April, 12 May and 17 June, the different colours represent changes that occurred on the ground. The Colorado River, which forms the border between Baja California and Sonora, can be seen cutting through the rich and colourful patchwork of agricultural land at the top right of the image, before it fans out and splits into multiple streams. 📸 contains modified @copernicus_eu Sentinel data (2019), processed by @europeanspaceagency

We have a lot to learn, but @hubbleesa is here to help‼️✨ ⠀⠀⠀ Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that chronological age alone does not tell the complete story when it comes to the evolution of star clusters. ⠀⠀⠀Previous research on the formation and evolution of star clusters has suggested that these systems tend to be compact and dense when they form, before expanding with time to become clusters of both small and large sizes. New Hubble observations in the Large Magellanic Cloud (LMC) galaxy have increased our understanding of how the size of star clusters in the LMC changes with time. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 @europeanspaceagency/@hubbleesa & @NASA; @creativecommons CC BY 4.0 🖥 @europeanspaceagency/@hubbleesa & @NASA, L.

Byron Bay, New South Wales

Happy Mid-Autumn to everyone celebrating‼️ 🌕 ⠀⠀⠀ This outstanding image of the Moon was taken by amateur photographer Dylan O’Donnell as the @iss passed by at 28 800 km/h. At such speeds the weightless research laboratory was visible for only about a third of a second before returning to the dark skies. ⠀⠀⠀ Do you know the connection between Mid-Autumn festival and the Moon? Have you ever eaten Mooncake? ⠀⠀⠀ Tell us your stories in the comment section 👇 ⠀⠀⠀ 📸 Public Domain - @dylan_odonnell_ ⠀⠀⠀

Our Education office, the @raspberrypifoundation and our ambassador Luca Parmitano, are happy to announce the launch of the 2019-20 European Astro Pi Challenge‼️ 🥳 The European Astro Pi Challenge is a school project run by us in collaboration with the Raspberry Pi Foundation and gives young people the opportunity to write code that runs on Raspberry Pi computers on board the @iss. Visit our website to start coding! 👉 http://bit.ly/EuropeanAstroPiChallenge20192020 📹 @europeanspaceagency / @raspberrypifoundation

The beauty of simplicity 🔘 ⠀⠀⠀ Things got heated on the @iss this week after the Multiscale Boiling experiment, known as Rubi, was successfully switched on. ⠀⠀⠀ Our astronaut Luca Parmitano installed the shoe box-sized container studying the boiling process in the Fluid Science Laboratory of the Columbus module after its arrival on a Dragon cargo resupply mission in August. ⠀⠀⠀ The experiment is now in full swing and generated its first bubble under controlled conditions. ⠀⠀⠀ While the bubbles form, a number of measurements are taken. The temperature sensor in the left of this image measures bubble temperature while a high-speed camera records how the bubbles behave and an infrared camera tracks the temperature of the heated region. ⠀⠀⠀ Scientists will also observe and quantify the effect of external forces on the boiling process. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 @europeanspaceagency ⠀⠀⠀

There’s beauty all around us‼️🤩 ⁠⠀⁠⠀ @youresa ・・・ After a challenging Monday we head to the beach in 🇳🇿 to enjoy a beautiful Moon-set and Milky Way with ⁠@joshkirkley⁠⠀ ⁠⠀⁠⠀ Thanks a lot for the invitation, Josh!⠀⠀⁠⠀⁠⠀⁠⠀ ______________________________________________________ ⁠⠀⁠⠀⁠⠀ 🌌 Don't forget to tag your @instagram stories with for a chance to be featured and visit the link in our bio to dance with the stars!⁠

Svalsat

📡 🛰 ⠀⠀⠀ Ground stations in remote polar regions are positioned to communicate with the polar-orbiting satellites passing over them. This is SvalSat, part of our Estrack global tracking network - it's the northernmost of our ground station! ⠀⠀⠀ 📹 @europeanspaceagency ⠀⠀⠀
