📷 This NASA/ESA #Hubble Space Telescope image shows NGC 1511, a spiral galaxy experiencing a burst of star formation. 🧪🔭
🔗 esahubble.org/images/potw2...

@science.esa.int @stsci.edu
A spiral galaxy, tilted away so that it is seen mostly from the edge. The disc of the galaxy glows blue from its centre, due to younger stars in the spiral arms. There are large and small patches of gas, glowing in red and pink colours, where new stars are forming. Webs of dark dust are spread over the disc. The glow of the disc fades into a dark background, with a couple of stars.

🛰️ Welcome to Kourou, #Galileo!

After crossing the Atlantic Ocean, two Galileo satellites have safely arrived in Kourou in preparation for their upcoming launch on Ariane 6 #VA266.

ESA, EUSPA and OHB SE teams are on site to prepare for the next launch from Europe's Spaceport in French Guiana.
After crossing the Atlantic Ocean by air, two Galileo satellites have safely arrived in Kourou and are unloaded from their transport aircraft in preparation for their upcoming launch. Before the Galileo satellites can be launched into space, they are transported to Europe's Spaceport for checks and integration on to the Ariane 6 rocket.

📷This is the Branco River in Brazil, as seen by #IRIDE HEO constellation. The near-infrared channel used to process this image helps us better distinguish between vegetated and areas where vegetation has been cleared, such as on the left of the image. 🧪🌏

This image shows the Rio Branco river from space. The river is black, and the surrounding forest is shown in bright red, with patches of grey highlighting areas where vegetation has been removed.

Insects on the space menu 🦗

👨‍🚀 @esa.int has gathered experts from across Europe to study whether these resilient and nutritionally rich creatures could become part of an astronaut’s meal.

🌍 Billions of people eat insects on Earth – have you eaten one before?

With final tests complete, ESA's HydroGNSS mission is set for launch this month. Part of the FutureEO programme, this Scout mission will use GNSS reflectometry to measure climate variables to improve understanding of Earth’s water cycle 🧪🌏

SWOOSH! 🧹 When a meteoroid struck Mars, it triggered ~100 dust avalanches down an ancient volcano's slopes.

@esa.int's ExoMars Trace Gas Orbiter captured the dramatic effect of the rare cascade. A new @nature.com study examines the most common causes of these streaks.

📷 This shimmering view from the ESA Euclid mission shows the dark cloud LDN 1641. Though nearly invisible to the human eye, Euclid’s infrared vision uncovers a rich landscape of gas, dust and dozens of newborn stars🧪🔭

@science.esa.int @ec-euclid.bsky.social
The focus of the image is a portion of LDN 1641, an interstellar nebula in the constellation of Orion. In this view, a deep-black background is sprinkled with a multitude of dots (stars) of different sizes and shades of bright white. Across the sea of stars, a web of fuzzy tendrils and ribbons in varying shades of orange and brown rises from the bottom of the image towards the top-right like thin coils of smoke.

The Sentinel-1 mission – which provides radar vision for the Copernicus Earth observation programme – has a new addition to its family of satellites, with the arrival in orbit of Sentinel-1D, the last of the groundbreaking first generation. The launch took place at 22:02 CET (18:02 local time), on Tuesday, 4 November, on board an Ariane 6 launcher from Europe’s Spaceport in French Guiana.

📷 What lies at the heart of this unusual-looking spiral galaxy? This NASA/ESA #Hubble Space Telescope image shows galaxy NGC 4102, home to what astronomers call an 'active galactic nucleus' 🧪🔭
Spiral galaxy NGC 4102. The inner region immediately around the bright centre is golden in colour. A gap separates this region from a bright ring, itself surrounded by a glowing halo. Strands of dark brown dust swirl around the centre and the outer ring, joined in one spot by a curved arm. Bright, blue and pink specks of light dot the ring, showing where stars are concentrated or have recently formed.

This image captured by the Copernicus Sentinel-3 mission on 26 October 2025 shows the ‘brightness temperature’ at the top of Hurricane Melissa as it moved through the Caribbean Sea towards Jamaica, where it was expected to make landfall. Part of the Red Spider planetary nebula: the nebula’s central star is hidden by a blotchy pinkish cloud of dust. A strong red light radiates from this area, illuminating the nearby dust.
