On 21 November, the Copernicus Sentinel-6 Michael Freilich satellite lifted off from the Vandenberg Air Force Base, California, US. The Copernicus Sentinel-6 Michael Freilich satellite is the first of two identical satellites to provide critical measurements of sea-level change. Since sea-level rise is a key indicator of climate change, accurately monitoring the changing height of the sea surface over decades is essential for climate science, for policy-making and, ultimately, for protecting the lives of those in low-lying regions at risk. Once in orbit and commissioned, this new mission will take the role of radar altimetry reference mission, continuing the long-term record of measurements of sea-surface height started in 1992 by the French–US Topex Poseidon and then the Jason series of satellite missions.
The Copernicus Sentinel-6 mission is a true example of international cooperation. While Sentinel-6 is one of the European Union’s family of Copernicus missions, its implementation is the result of the unique collaboration between ESA, NASA, Eumetsat and NOAA, with contribution from the French space agency CNES.

Ahead of the upcoming Ariane 5 launch of the James Webb Space Telescope, the Copernicus Sentinel-2 mission takes us over Kourou – home to Europe’s Spaceport in French Guiana, an overseas department of France.
Located around 60 km northwest of the French Guianese capital Cayenne, Kourou is a coastal town in the north-central part of the country and is visible in the lower right of the image. The town lies at the estuary of the Kourou River which, after its journey of 144 km, empties into the Atlantic Ocean. Its muddy waters appear brown most likely due to sediments picked up from the surrounding forest.
Long, white sandy beaches line the town’s ocean coast, while the riverbank and inland area consists mostly of mangrove and dense tropical rainforest. The surrounding area’s economy is largely agricultural, with coffee, cacao and tropical fruits being grown.
Just northwest of Kourou lies Europe’s Spaceport – chosen as a base from which to launch satellites in 1964 by the French Government, and currently home to ESA-developed rocket families Ariane and Vega.
As Kourou lies just 500 km north of the equator, it makes it ideally placed for launches into orbit as the rockets gain extra performance thanks to a ‘slingshot effect’ from the speed of Earth’s rotation. In addition, there is no risk of cyclones or earthquakes. This launch base and the jungle that surrounds it covers 690 sq km and protects an abundance of wildlife and plants.
From here, the largest and most powerful telescope ever launched into space – the James Webb Space Telescope – is scheduled for launch. After liftoff, it will embark on a month-long journey to its destination, around one and a half million kilometres from Earth.
Following the footsteps of the Hubble Space Telescope, Webb is designed to answer questions about the Universe and to make breakthrough discoveries in all fields of astronomy. The telescope will be able to detect infrared light generated by galaxies as they formed more than 13.5 billion years ago, in the aftermath of the Big Bang. Webb will see farther into our origins – from the Universe's first galaxies, to the birth of stars and planets, to exoplanets.
In the first month after launch, Webb will unfold its sunshield, which is around the size of a tennis court, and deploy its 6.5-metre primary mirror. This will be used to detect the faint light of distant stars and galaxies with a sensitivity of a hundred times greater than that of Hubble.
Webb is a joint project between NASA, ESA and the Canadian Space Agency (CSA). Find out more about Webb in ESA’s launch kit and interactive brochure.

no es cualquier ventana. No. Es una de las ventanas de la casa del campo de mis padres y que antes fue de mi abuelo. Lugar en el que jugué y de la que tengo lindos recuerdos. Casa que ya no me resultaba tan querida y entrañable en mi adolescencia cuando pasarme un finde en el campo no era el mejor programa, aunque a veces si me llevaba amigas con quienes compartir podia ser el mejor plan. Luego, ya con hijos el campo volvió a ser el mejor lugar en el que compartimos infinidad de aventuras. Y ahora con hijos adolescentes tengo la suerte de que como vamos poco y siempre invitan amigos para ellos es un buen programa.

La vieja casa en silencio
y ninguno se lo explica,
cómo pasan esa cosas
tan feliz que parecía.
Mi madre llora en el patio,
Pedro duerme en la cocina,
y ninguno se ha acordado
de que coman las gallinas.
María llega de lejos
ella que nunca venía,
y el tío Luis a mi hermano
le dice un par de mentiras.
El crucifijo de plata
se lo lleva Catalina,
la mecedora Francisco
y la mantilla Corina.
El perro no entiende nada,
el gato ya lo sabía,
él fue después del abuelo
el que más la conocía.
La vieja casa en silencio
y ninguno se lo explica,
cómo pasan esas cosas
tan feliz que parecía.
Cómo pasan esas cosas...
tan feliz que parecía!

Captured by Copernicus Sentinel-2 on 11 January 2026, this image shows active wildfires near Lake Rivadavia in Los Alerces National Park, Argentina, observed from low Earth orbit. This protected area is home to ancient Alerce trees (Fitzroya cupressoides), among the longest-living on Earth, with some standing for more than 3600 years. Fires like this pose a serious threat to a unique ecosystem.
Shown in false colour, the image highlights burned areas in brown, the active fire front in red and orange, and snow-covered regions in light blue, contrasted against white clouds.
From orbit, Earth-observing satellites help track wildfires in near-real time, delivering vital data to support emergency response and environmental protection on the ground.

Different types of crops growing east of the Czech capital, Prague (left), are distinguished in this land cover classification image.
This crop map was created by combining over 1000 scenes from the Sentinel-1, Sentinel-2 and Landsat-8 satellites taken over the course of 2015.
With its 13 spectral bands, the Sentinel-2 mission for Europe’s Copernicus programme is the first optical Earth observation mission of its kind to include three bands in the ‘red edge’, which provide key information on vegetation state.
Sentinel-2 is designed to provide images that can be used to distinguish between different crop types as well as data on numerous plant indices, such as leaf area, leaf chlorophyll and leaf water – all essential to monitor plant growth accurately.
This image was produced in collaboration with the European Commission (lead by the Joint Research Centre), the State Agricultural Intervention Fund of the Czech Republic and ESA.

Deliciosa sesión en Vegueta con la inmejorable compañía de Cristo Bolaños y la maravillosa modelo Ariadna Quintana
Mentiría si asegurase haber olvidado ese otoño. tu abrigo, tus manos frías, tantas tardes contigo. debo afirmar que, en ese entonces, nadie había calado jamás tan hondo en mi. hace un año entero de ese miércoles, y nadie me hubiera podido convencer entonces de que todo esto iría así. hay tanto que decir, tantos momentos, tanto pasado, que las palabras resultan pequeñas, vacíos trazos de tinta que no llegan a emular la vida que hubo en esas miradas azules.
te agradezco ese pasado, el poder mirar atrás y esbozar una sonrisa, aunque todo haya cambiado, hay momentos y personas que jamás se olvidan.
sé feliz.

Engineers stand in front of the Jupiter Icy Moons Explorer (Juice) with the high-gain antenna in full view, while the medium-gain antenna at top right is inspected from above. The high-gain antenna is covered with a temporary protective sheet that will later be removed.
Juice will make detailed observations of Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for the numerous giant exoplanets now known to orbit other stars.

The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope Picture of the Week is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms and bright blue star clusters. Also captured in the upper left-hand corner of this image is a far closer object: a star just 577 light-years away in our own galaxy.
UGC 5460 has hosted two recent supernovae named SN 2011ht and SN 2015as. It’s because of these two stellar explosions that Hubble targeted this galaxy, collecting data for three observing programmes that aim to study various kinds of supernovae.
SN 2015as was what’s known as a core-collapse supernova: a cataclysmic explosion that happens when the core of a star far more massive than the Sun runs out of fuel and collapses under its own gravity, initiating a rebound of material outside the core. Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.
SN 2011ht might have been a core-collapse supernova as well, but it could also be an impostor called a luminous blue variable. Luminous blue variables are rare stars that experience eruptions so large that they can mimic supernovae. Crucially, luminous blue variables emerge from these eruptions unscathed, while stars that go supernova do not. Hubble will search for a stellar survivor at SN 2011ht’s location, and the explosion’s identity may be revealed at last.
[Image Description: A spiral galaxy seen close to face-on. The centre of its disc is a bright, pale yellowish oval shape. Spiral arms extend from either side of the oval through the disc on irregular paths. They are marked throughout by bright bluish-white patches of stars. Distant background galaxies appear as small orangish blobs around the spiral galaxy. In the top-left corner a nearby star shines brightly, spikes radiating from it.]

A snapshot taken a second before a powerful M-class solar flare was unleashed from the Sun on 30 September 2024 – as seen in unprecedented detail by the ESA-led Solar Orbiter mission.
The image is an excerpt from a video created from Extreme Ultraviolet Imager (EUI) images taken every two seconds leading up to the solar flare.
This frame captures the moment a dark filament of twisted magnetic field lines dripping with plasma rises from the surface. It captures the unravelling of the rope-like filament as one end (towards the bottom of the frame) becomes detached, launching into space. The unwinding closest to the connected end is recorded at 250 km/s, increasing to 400 km/s at the site of disconnection.
Bright sparks are seen all along the filament in stunning high resolution, representing sites of reconnection – where twisted magnetic field lines break apart and reconnect, creating a surge of energy.
The complete sequence of high-resolution imagery revealed that just as avalanches on snowy mountains start with the movement of a small quantity of snow, a solar flare is triggered by initially weak disturbances that quickly become more violent. This rapidly evolving process creates a ‘sky’ of raining plasma blobs that continue to fall even after the flare subsides.
Solar Orbiter is a space mission of international collaboration between ESA and NASA. The EUI instrument is led by the Royal Observatory of Belgium (ROB).

This view was generated from the digital terrain model and the nadir and colour channels of the High Resolution Stereo Camera on ESA’s Mars Express.
It shows a bird’s-eye view of a crater lying in Mars’s ancient southern highlands, located just next to a far larger basin named Trouvelot Crater. It shows dark, volcanic deposits covering the crater floor and wall. The crater measures around 30 km across.
[Image description: A close-up, angled view of a Martian crater. The large circular crater dominates the scene, with steep, shadowed inner walls and a smooth, sandy-looking floor. The surrounding terrain is pale reddish-brown and gently sloping, dotted with a few smaller craters. The lighting highlights the rugged edges of the main crater against the otherwise smooth landscape.]

This new picture from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). Herbig-Haro objects are luminous regions surrounding newborn stars (known as protostars), and are formed when stellar winds or jets of gas spewing from these newborn stars form shockwaves colliding with nearby gas and dust at high speeds. HH 797, which dominates the lower half of this image, is located close to the young open star cluster IC 348, which is located near the eastern edge of the Perseus dark cloud complex. The bright infrared objects in the upper portion of the image are thought to host two further protostars.
