🎄 Are your holiday decorations ready? Euclid has a cosmic garland to add: NGC 646.

The large barred spiral galaxy appears close to a smaller galaxy to the left, but they’re actually about 45 million light-years apart 👉 https://www.esa.int/ESA_Multimedia/Images/2025/12/Euclid_s_galaxy_garland
🔭
An image of space made by the Euclid telescope shows a bright barred spiral galaxywith two sweeping arms glowing in shades of blue and white against a deep black background dotted with stars. Its core is luminous. Its spiral arms curve gracefully outward to the left and down to the right, resembling a cosmic garland draped across the scene. A smaller, faint and round galaxy appears to the left of the barred spiral galaxy.

The #CM25 historic increase of 3.5% per year beyond inflation for Science will enable some of the most imaginative missions in our history and bolster European scientific leadership.

First step: deliver the #CosmicVision missions such as LISA & NewAthena. The next great leap is #Voyage2050 🔭 🧪

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.

Curious how air pollution looks from space? 🌍
The 1st images from Sentinel-4 show us, offering an early glimpse of its capability to monitor Europe’s air quality hourly!

Onboard our new #MTGS1 satellite it will help deliver faster warnings to save lives & boost economies.

Tropospheric nitrogen dioxide concentrations measured over Europe on 8 Oct.
High concentrations can be seen in Italy’s Po Valley, along the north coast of Africa, and in other hotspots.
NO2 is released during the combustion of fossil fuels and is known to exacerbate various health conditions. 😷

High concentrations can be seen over Sicily, a signature of plumes from Mount Etna. 🌋
SO2 can contribute to health problems including heart & lung disease.

😎 First glimpses from space!

The new #Copernicus Sentinel-4 mission has delivered its first preliminary images during commissioning.

Sentinel-4’s spectrometer is hosted on @eumetsat.int's MTG-S1 satellite 🧪🌍

@josefaschbacher.esa.int @ec.europa.eu @esaearth.esa.int
The new Copernicus Sentinel-4 mission has delivered its first images, highlighting concentrations of atmospheric nitrogen dioxide, sulphur dioxide and ozone. Despite being preliminary, these images mark a major milestone in Europe’s ability to monitor air quality all the way from geostationary orbit, 36 000 kilometres above Earth. This image depicts tropospheric nitrogen dioxide with clear pollution hotspots visible along the Mediterranean coast and over Italy’s Po Valley. This image presents a vertical column density of sulphur dioxide. A distinct plume can be seen emerging from Mount Etna in Italy and drifting south-eastwards over the sea. Although Etna is currently relatively calm, much larger plumes are typically observed during periods of heightened volcanic activity. In addition to natural emissions from volcanoes, sulphur dioxide is also released through human activities, particularly from ships burning high-sulphur fuels and power plants using brown coal. This image shows a vertical column of ozone. While ozone high up in the stratosphere plays a crucial role in shielding life on Earth from harmful ultraviolet radiation, ozone in the lower atmosphere acts as a pollutant, contributing to poor air quality and respiratory problems. The overall ozone levels here are within the expected range. This image of Europe and part of North Africa is based on the first Earth radiance spectra measured by Sentinel-4. The false-colour image, generated by assigning the signals in specific spectral ranges to red, green and blue, shows the land, ocean and clouds as expected.
