From 25 July 2014 to 15 January 2025, the Gaia space observatory performed high-precision measurements of nearly two billion stars from its Lissajous orbit around the L2 Lagrange point, 1.5 million km from Earth.
After 10.5 years of groundbreaking observations, Gaia’s cold gas supply for attitude control has been depleted. On 27 March 2025, Gaia will leave its Lissajous orbit and transition into a stable heliocentric orbit. Soon after, the spacecraft will be passivated, with its instruments and transmitters switched off.
While Gaia will no longer collect new data, its scientific mission is far from over! The team continues working on Gaia Data Release 4 (expected 2026) and the final legacy catalogue (to be published not before the end of 2030), ensuring that Gaia’s discoveries will shape astronomy for decades to come.
This video visualises how Gaia leaves its Lissajous orbit and enters its final heliocentric orbit.

On 19 March 2025, our Euclid mission released its first batch of survey data, revealing an astonishing view of the cosmic web.
With just one scan of its deep fields, Euclid has already detected 26 million galaxies, some as far as 10.5 billion light-years away! This is just a preview of what’s to come, as Euclid will continue mapping the Universe in unprecedented detail.
What’s in this first release? – Three vast mosaics covering 63 square degrees of the sky – A catalogue of 380 000 galaxies, classified with AI + citizen scientists – 500 new gravitational lens candidates, almost all never seen before – The first hints of Euclid’s full cosmic atlas, which will eventually cover one-third of the sky
This data is a huge leap forward in understanding how galaxies are distributed across the Universe and how dark matter and dark energy shape the cosmos.
Over the next six years, Euclid will revisit these deep fields 30 to 52 times, uncovering billions of galaxies and pushing the astrophysics’ boundaries.

Using data from the European Space Agency’s Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia’s ability to sense the gravitational tug or ‘wobble’ the planet induces on a star. Both the planet and brown dwarf are orbiting low-mass stars, a scenario thought to be extremely rare.

At present it’s as though the distance ladder observed by Hubble and Webb has firmly set an anchor point on one shoreline of a river, and the afterglow of the Big Bang observed by our Planck mission from the beginning of the Universe is set firmly on the other side. How the Universe’s expansion was changing in the billions of years between these two endpoints has yet to be directly observed.

This image was captured by NIRCam, Webb’s primary near-infrared camera, and contains the lensing galaxy cluster SDSS J1226+2149. It lies at a distance of around 6.3 billion light-years from Earth, in the constellation Coma Berenices. By combining Webb’s sensitivity with the magnifying effect of gravitational lensing, astronomers were able to use this gravitational lens to explore the earliest stages of star formation in distant galaxies. To do so, they relied on earlier studies by the NASA/ESA Hubble Space Telescope, which provided the ‘prescription’ for this gravitational lens.

This video takes the viewer on a journey through space to the Rho Ophiuchi cloud complex.
From our cosmic backyard in the Solar System to distant galaxies near the dawn of time, the NASA/ESA/CSA James Webb Space Telescope has delivered on its promise of revealing the Universe like never before in its first year of science operations. To celebrate the completion of a successful first year, a new Webb image has been released of a small star-forming region in the Rho Ophiuchi cloud complex. While the region is relatively quiet, its proximity at 390 light-years makes for a highly detailed close-up, with no foreground stars in the intervening space.

ESA’s latest astrophysics mission, Euclid, lifted off on a Space X Falcon 9 from Cape Canaveral in Florida, USA, at 17:12 CEST on 1 July 2023.
Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometres from Earth, in the opposite direction from the Sun.
The telescope will survey one third of the sky with unprecedented accuracy and sensitivity. By observing billions of galaxies out to 10 billion light-years, it will create the most extensive 3D-map of the Universe, with the third dimension representing time.
ESA’s Euclid mission is designed to explore the composition and evolution of the dark Universe. Euclid will chart how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.
Four weeks after launch, Euclid will enter its orbit around L2. Once in orbit, mission controllers will start the activities to verify all functions of the spacecraft, check out the telescope and finally turn the instruments on. Following this, scientists and engineers will be engaged in an intense two-month phase of testing and calibrating Euclid’s scientific instruments, and preparing for routine observations. The telescope begins its early phase of the survey of the Universe three months after launch.

Watch Mercury appear from the shadows as the ESA/JAXA BepiColombo spacecraft sped by the planet’s night side during its 19 June 2023 close flyby, and enjoy a special flyover of geologically rich terrain.
The first part of the movie is composed of 217 images captured by BepiColombo’s monitoring camera M-CAM3. The image sequence starts from 19:46:25 UTC on 19 June 2023, at an altitude of 1 789 km above the planet’s surface, and ends at 20:34:25 UTC on 20 June 2023, when BepiColombo was 331 755 km away. The image cadence was roughly once per minute around closest approach, but much slower in the later phases.
The second part of the movie cuts to a flyover of a special region of interest, rotating around features such as the 600 km-long Beagle Rupes curved escarpment and the elongated Sveinsdóttir impact crater that it cuts through. It also features the 218 km-wide Manley Crater and the straight Challenger Rupes scarp. At the end, the animated topography fades out and the projected image used for 3D reconstruction appears. Regions like these will be important for BepiColombo’s main science mission, to learn more about Mercury’s geological history.
Music was composed for the sequence by ILĀ, with the assistance of AI tools developed by the Machine Intelligence for Musical Audio (MIMA) group, University of Sheffield.

ESA’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.
To better understand what dark matter and dark energy may be, we need a mission that can more closely reveal what effects they have had on galaxies, galaxy clusters and the expansion of the Universe itself. Euclid is that mission.
ESA’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.
From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.

This video takes the viewers on a journey to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.
With its ability to peer through the gas and dust enshrouding newborn stars, the NASA/ESA/CSA James Webb Space Telescope is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI and NIRCam — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.

More than 5000 exoplanets have been discovered to date, but what do they look like? ESA’s dedicated exoplanet missions Cheops, Plato and Ariel are on a quest to find out. Cheops will focus its search on mini-Neptunes, planets with sizes between Earth and Neptune, on short orbits around their stars. Cheops will find out how large these planets are, and may detect whether the planets have clouds. Plato will look at all kinds of exoplanets and determine their sizes and ages. Plato’s instruments are so sensitive it may discover the first Earth-like planet on an Earth-like orbit. Finally, Ariel will look at the atmospheres of exoplanets using the technique of transmission spectroscopy and discover what they are made of. Together these missions will discover what exoplanets and their systems look like and they will also reveal how special our own Solar System is.

Using data from our Gaia mission, astronomers have discovered not only the closest but also the second closest black hole to Earth. The black holes, Gaia BH1 and Gaia BH2, are respectively located just 1560 light-years away from us in the direction of the constellation Ophiuchus and 3800 light-years away in the constellation Centaurus. In galactic terms, these black holes reside in our cosmic backyard.
The two black holes were discovered by studying the movement of their companion stars. A strange ‘wobble’ in the movement of the stars on the sky indicated that they are orbiting a very massive object. In both cases, the objects are approximately ten times more massive than our Sun. Other explanations for these massive companions, like double-star systems, were ruled out since they do not seem to emit any light.

ESA’s Gaia mission has helped discover a new kind of black hole. The new family already has two members, and both are closer to Earth than any other black hole that we know of.
The two black holes were discovered by studying ultra-precise measurements of stellar positions and motions in Gaia’s third data release.

This sequence was taken by Solar Orbiter’s Extreme Ultraviolet Imager using the Full Sun Imager telescope, and shows the Sun at a wavelength of 17 nanometers. This wavelength is emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees. The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.

“After Euclid’s lifetime, it will just be floating in space. What if future beings found Euclid? How would they know anything about the humanity of the people?” – Tom Kitching, lead scientist of Euclid’s VIS instrument.
The team behind ESA’s Euclid mission has come together to create something special – a personal and collective galaxy-shaped fingerprint painting that has been attached to the spacecraft ready to launch into space. The collaborative nature of the artwork reflects the collaborative nature of the Euclid project overall; in both cases, people have come together to build something unique.
The Fingertip Galaxy was created by visual artist Lisa Pettibone and Euclid instrument scientist Tom Kitching. Since the very first fingerprint was pressed down in 2019, over 250 scientists and engineers have contributed to the piece of art.
So why a galaxy? Euclid is a galaxy-imaging machine that will observe billions of galaxies out to 10 billion light-years to make a 3D map of the Universe. The mission’s ultimate aim is to explore dark matter and dark energy.
“Although Euclid has always been beautiful in concept and materials, it didn’t really say anything about the people involved and humanity as a whole. We asked ourselves whether we could do something artistic that would speak to people,” says Lisa.
Scientists and engineers involved in Euclid were invited to dip their fingertips in paint and make their mark on a large piece of paper.
“We wanted something authentic, not perfect, and not shaped too much,” continues Lisa. “The result is a piece of art with a wonderful energy to it that captures all the energy of the people involved.”
The artwork was photographed and engraved onto a plaque using lasers at Mullard Space Science Laboratory – the same lasers that are used to etch parts for satellites. The plaque was fixed to Euclid and revealed at a ‘Goodbye Euclid’ event on 1 July 2022, when Euclid left Thales Alenia Space in Turin to head to Cannes for final testing as a complete system.
Euclid’s project scientist René Laureijs suggested adding text to the plaque to explain the thoughts behind it. Continuing the artistic nature of the project, poet Simon Barraclough wrote a dedicated poem, from which a short extract was chosen to be etched on to the plaque in a typewriter font that swirls around the galaxy of fingerprints. This video ends with Simon reading part of Since his poem.
Lisa summarises the Fingertip Galaxy: “It is adding an element of humanity to a dark, vast space, where as far as we can see there is no other intelligent life.”

On March 21, 2022, the number of known exoplanets passed 5,000 according to the NASA Exoplanet Archive. This 360-degree animation and sonification tracks humanity’s discovery of the planets beyond our solar system over time. Turning NASA data into sounds allows users to hear the pace of discovery with additional information conveyed by the notes themselves.
As each exoplanet is discovered, a circle appears at its position in the sky. The size of the circle indicates the relative size of the planet’s orbit and the color indicates which planet detection method was used to discover it. The music is created by playing a note for each newly discovered world. The pitch of the note indicates the relative orbital period of the planet. Planets that take a longer time to orbit their stars are heard as lower notes, while planets that orbit more quickly are heard as higher notes.
