In space, not everything is what it seems. This Picture of the Week shows the nebula Sh2-46, also named Gum 80, situated roughly 6000 light-years away. The strong red hues of Sh2-46 might be beautiful, but they hide an impostor.
\r\nThe big blue-white star at the centre of the image is HD 165319, an O type star, one of the brightest, but rarest types of stars in the Universe. The star is largely responsible for the striking red tones around it, caused by the ionisation of the hydrogen atoms that make up the nebula. This star, however, should not be here.
\r\nAstronomers think that this star was born somewhere else: in the nearby Eagle Nebula. Located in the tail section of the Serpens constellation (the snake), the Eagle Nebula is full of star-forming regions. Once born, these stars become bound by gravity, creating a giant open cluster. Sometimes, though, a few of them become disentangled, embarking on a solitary mission through space that can lead them to infiltrate other unrelated nebulae. A bow shock next to HD 165319 seems to indicate that the star is currently plunging through Sh2-46. Perhaps this nebula will end up looking differently if the star ends up leaving it behind…
\r\nThis highly detailed picture of Sh2-46 was taken by the VLT Survey Telescope (VST), which explores the sky in visible light. Currently owned by INAF, the Italian National Institute for Astrophysics, the VST is located at ESO’s Paranal Observatory, in Chile. This image is being released on the occasion of the 100 years of the Planetarium, with a full-dome version being shown at the ESO Supernova Planetarium & Visitor Centre.

During explosions like this, shock waves ripple out through the surrounding gas, compressing it into intricate thread-like structures. The energy that’s released during a supernova then heats these threads, causing them to shine brightly. The result is what we can see in this Picture of the Week: the Vela supernova remnant.
\r\nThis picture is just a small chunk of a much larger image, taken with the OmegaCAM instrument on the VLT Survey Telescope (VST), which is hosted at ESO’s Paranal Observatory. At only 800 light-years from Earth, the Vela supernova remnant is one of the closest examples of these dramatic events. Thanks to its proximity we can study this object in great detail, to help us understand what happens when massive stars reach the end of their life in spectacular fashion.

Attentive viewers may find that part of Gum 3 resembles a Koi fish in this VST image. Equipped with the OmegaCAM instrument, an enormous 268-megapixel camera, the telescope is designed to survey large areas of the southern sky in visible light and take stunning images like this one.
\r\nGum 3 is an interstellar cloud of gas and dust located about 3600 light-years away, between the Monoceros and Canis Major constellations. It is named after Colin Stanley Gum, an Australian astronomer who catalogued 84 nebulae in the southern sky.
\r\nWhen the intense ultraviolet radiation from nearby young stars hits hydrogen atoms in the cloud, they emit visible light at very specific colours, which we see as shades of red and pink in the image. At the same time, tiny particles of dust within the cloud reflect starlight, especially blue colours, similar to what makes the sky look blue here on Earth. This play of colours makes nebulae like this spectacular to look at.
\r\nThis image shows not only colour, but also the lack of it. Look closely at the area just right of the brightest part of the cloud — right of the pink “Koi-smic fish”. Does anything look odd to you? It’s not that there really are fewer stars in this dark area; instead, there is a big clump of dust that blocks part of the visible light, hiding the stars from VST and us.

\r\nThe picture was taken with ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA), operating in Chile’s Atacama Desert.

As VISTA observes infrared light, it is able to peer through most of the dust in this region, which would block our view when observing in visible light. Behind the dust, VISTA is showing young stars within dusty cocoons and cold ‘failed’ stars known as brown dwarfs, thus revealing the secrets within these young stellar nurseries.

\r\nThis animation illustrates how astronomers can infer the strength of magnetic fields in exoplanets from their effect on the winds on these planets.
\r\nThe planets shown here are gas giants like Jupiter, but they are tidally locked: one side is constantly facing the star and is therefore much hotter than the other side. This temperature difference drives powerful winds from the day side to the night side. We expect these winds to be faster on planets that are overall hotter, as they have more energy to power the winds. This is shown at the beginning of the animation, with the wind speed indicated by a speed meter.
\r\nThe winds carry charged particles –– ions and electrons –– like a giant, planet-sized electrical circuit. The magnetic field of the planet dissipates the energy of these particles, slowing down the wind. This effect is more pronounced in hotter planets: the higher temperatures break down more molecules into ions and electrons, making the wind more susceptible to this magnetic drag. This is shown in the second part of the animation, where the hotter planet to the right ends up having slower winds than the colder planet.
\r\nUsing spectrographs astronomers can measure the temperature and wind speed on exoplanets. A trend of decreasing wind speed with increasing temperature can betray the presence of magnetic fields on these planets.

\r\nThis animation shows magnetic activity in an exoplanet. The planet is a gas giant like Jupiter, but it’s very close to its host star and tidally locked: one side always faces the star and is scorching hot, whereas the other side is extremely cold. This steep temperature difference creates fast winds that blow from the day side to the night side. The planet’s magnetic field, shown here with blue lines, can slow these winds down.

This swirling cloud is a planetary system in formation and it is the perfect example to study their structure, letting us take a closer look at the dynamics of planet birth.
\r\nAB Aurigae is located in the Auriga constellation, 520 light-years away from Earth. While the overall rotation of the material within the disc is governed by the star’s gravity, there are features like “twists” signalling the places where planets could be forming. As the new planets interact with surrounding material and feed with gas and dust, they create disturbances that cause this phenomenon as the planet rotates around the star. These features are better seen in the right side of the video, which has been processed to enhance these structures.
\r\nThe images were taken with the SPHERE instrument at the VLT, which blocks the glare of the central star, revealing the disc around it in great detail. In particular, the images show radial shadows caused by opaque clumps from denser parts of the disc that can be seen orbiting this star. These SPHERE observations will be key to understanding the precise way in which planets form around this star.
\r\nFour laser beams shine across the magnificent Southern sky in this timelapse video. Each laser comes from one of the four Unit Telescopes (UTs) of ESO’s Very Large Telescope (VLT), here working together as part of the VLT Interferometer (VLTI). A glowing bead of light appears sequentially on each beam, produced by the interaction of each laser with passing thin clouds. These spots were a happy accident, as the lasers themselves target a much higher layer in our atmosphere: 90 kilometres above the Earth’s surface.
\r\nThe ELT Explorer is a virtual, realistic and interactive visit to the digital twin of the Extremely Large Telescope (ELT), an astronomical facility of the European Southern Observatory (ESO) currently under construction in Chile’s Atacama Desert.

\r\nThe video combines images taken with different telescopes at different times and various wavelengths. The clip begins with a wide view of the night sky in visible light. It then transitions to an infrared image captured with ESO’s Visible and Infrared Telescope for Astronomy (VISTA). The video ends with a closeup taken with ESO’s Very Large Telescope (VLT), showing both planets carving out gaps in the disc around the star. The star itself is not visible in this last image, as its light has been blocked to reveal the faint structures around it.

\r\nThis video shows a portion of the Triangulum galaxy, also known as Messier 33, at different colours or wavelengths of light. The data were taken with the MUSE instrument at ESO’s Very Large Telescope (VLT) in Chile, and it shows complex filamentary clouds within this galaxy.
\r\nMUSE decomposes the incoming light from astronomical sources into its constituent colours, but it does so at every single point within its field of view. In other words: it allows us to image astronomical objects at thousands of colours simultaneously.
\r\nAs the video scans through the dataset, the galaxy lights up at very specific wavelengths where certain atoms like hydrogen, oxygen or sulphur shine brightly. These observations allow astronomers to map the distribution of different chemical elements in great detail, and to better understand the interplay between these gas clouds and the stars that form within them.
\r\nWith its 39 m primary mirror, ESO's Extremely Large Telescope (ELT) will be the biggest and most powerful optical telescope in the world. In this episode of Chasing Starlight we take you on an exclusive tour of the ELT, from the massive telescope structure inside the dome to the facility that will coat the mirrors with reflective silver.

\r\nAPEX is a telescope designed to explore cold, dark regions of our Universe, such as dense clouds of gas and cosmic dust where new stars are born. While visible light is obscured by the dust, these regions glow bright at the (sub)millimetre wavelengths that APEX observes. APEX allows astronomers, among other things, to study the chemical conditions within these clouds, detecting a variety of molecules in these dark, distant regions of our Universe.
\r\nWater vapour in the atmosphere absorbs these wavelengths. That's the reason APEX is located on the Chajnantor plateau in Chile’s Atacama Desert at an altitude of 5100 m: one of the driest regions on Earth with few clouds.
\r\nOnce a joint project of the Max-Planck Institute for Radio Astronomy (MPIfR), the Onsala Space Observatory (OSO) and ESO, APEX now enters a new chapter and becomes a project solely of the MPIfR. But the science continues!

The video, taken by Juan Beltrán, an instrumentation technician at ESO’s Paranal Observatory in Chile, marks the beginning of a new interferometry era.
\r\nMost of the time these so-called Unit Telecopes (UTs) work as standalone telescopes, each one observing a different object. But they can also point at the same target, combining their light with interferometry to obtain the same level of detail of a huge 130 m virtual telescope. This requires measuring and correcting the effects of Earth’s atmosphere, which was previously done through bright reference stars, hard to find next to the object one wants to study.
\r\nAs part of the GRAVITY+ upgrade, new lasers were installed in the previously unequipped UTs. These lasers create artificial stars high up in the atmosphere, near the observation target on sky, that can be used to correct atmospheric turbulence. Now that the lasers are ready, the observations are not limited to natural bright reference stars anymore, opening the whole southern sky to the VLTI. And the GRAVITY+ trial run in early November blessed us with the mesmerising view of all four lasers pointing to one target on the sky, as if they were fist bumping as a team.
\r\nWhat’s the biggest black hole in existence? This video takes you on a journey through the universe to compare black holes of all sizes — from stellar remnants just a few kilometers wide to the mind-bending supermassive monsters that can engulf entire solar systems. Discover how these cosmic giants form, how big they can grow, and what happens if you get too close to their event horizon.

About 22 million light-years away the supernova, SN 2024ggi, exploded in the galaxy NGC 3621. Using the ESO’s Very Large Telescope, astronomers managed to capture the very early stage of the supernova when the blast was breaking through the star’s surface. Observing the breakout so early on — 26 hours after the supernova was first detected — revealed its true shape. The supernova broke out in an olive-like form. This marks the first ever observation of the shape of a supernova explosion at this very early stage.
\r\nAs the explosion spread outward and collided with the material around the star, its shape flattened and its axis of symmetry rotated. Yet deep within the blast, the ejecta’s axis of symmetry, untouched by the surrounding matter and revealed by later observations, remained unchanged.

Today’s Picture of the Week is a timelapse of an important milestone: the first movement of one of the dome’s giant doors.
\r\nThe ELT dome and its doors guard the telescope from the harsh conditions of the Atacama Desert in Chile. Each of the doors will weigh approximately 650 tonnes once completed, including walkways, ducts for heating, ventilation and air conditioning, and other related mechanisms already installed. Moving these massive doors is no small feat, and the test shown in this timelapse, captured in early October, is key to ensuring that everything works as it should.
\r\nOnce both doors are fully installed and operational they will be closed, providing a more stable and controlled environment inside the dome for the upcoming construction phases. These include installing critical systems like the hydrostatic oil bearings that will allow for a smooth and precise movement of the telescope. Once the ELT is in operation the doors must respond quickly to protect the telescope against sudden changes in the external conditions. At night, the doors will allow the biggest eye on the sky to scrutinise Chile’s uniquely dark skies.

Located about 620 light-years away, this rogue planet is about 5-10 times more massive than Jupiter and doesn’t orbit a star. The planet is eating up material from a disc around it and, using ESO’s Very Large Telescope (VLT), astronomers have discovered that it is now doing so at a rate of six billion tonnes per second –– the fastest ever found for any kind of planet. This is illustrated shortly after the clip begins, where the flow of gas and dust from the disc onto the planet intensifies. The team suspects that strong magnetic fields could be funnelling material towards the planet, something only seen in stars before.
\r\nWhen the infalling material reaches the planet it heats up its surface, creating a bright hot spot. The X-shooter spectrograph on ESO’s VLT detected a marked brightening in mid-2025, and found a clear fingerprint that this was caused by infalling gas. The observations show that the planet is now accreting matter about 8 times faster than a few months before.

\r\nThe video combines images taken with different telescopes at different times and various wavelengths. It begins with a wide view of the night sky in visible light. As we zoom in, we switch to an infrared view taken with ESO’s Visible and Infrared Telescope for Astronomy (VISTA). Finally, we show an artist’s animation of the planet, which is eating up gas and dust from a disc around it. Using ESO’s Very Large Telescope (VLT), astronomers have found this is now happening at a rate of about 6 billion tonnes per second.

In 2031, Japan’s Hayabusa2 spacecraft is planned to rendezvous with this tiny asteroid, after its prior successful mission to the much larger 162173 Ryugu in 2018. Ryugu is 900 metres wide and can be seen in this video looming behind 1998 KY26, although in reality both asteroids follow very different orbits, and are only shown close together in this animation for comparison While both asteroids are spinning, 1998 KY26 spins much more quickly, further complicating Hayabusa2’s future touchdown.

Now, using observations from 2017, 2018 and 2021, astronomers have found some changes in this now iconic image that could be caused by variations in the magnetic field around the black hole.
\r\nNote that the Greenland Telescope (GLT) was added to the EHT in 2018: it was left out of the map at 7:58 by mistake.
\r\nThis video zooms in on the gamma-ray burst GRB 250702B, a powerful explosion that repeated several times over the course of a day on 2 July, an event unlike anything ever witnessed before. The event took place in another galaxy, but its cause remains unknown.
\r\nThe video combines images taken with different telescopes at different times and various wavelengths. The journey begins with a wide-field view of the sky in visible light, which then switches to infrared light. The video ends with a sequence of infrared images taken with ESO’s Very Large Telescope showing the aftermath of the explosion, with the source fading from 3 July (one day after the explosion) to 15 July.

\r\nThis sequence of images shows the evolution over several days of the gamma-ray burst GRB 250702B. This GRB was first observed with high-energy telescopes on 2 July, which detected several flares of gamma rays over the course of a day.
\r\nAstronomers then used ESO’s Very Large Telescope (VLT) to pinpoint the exact location of the explosion and monitor how its so-called afterglow faded over several days.
\r\nThe images shown here were taken with the VLT’s HAWK-I infrared camera. For clarity, only the central area updates from one frame to the next. The explosion appears to be nested within an elongated galaxy, later confirmed by the NASA/ESA Hubble Space Telescope.
\r\nIn the last 30 years we've discovered around 6000 planets orbiting other stars. But how do astronomers find these exoplanets? And can we take real images of them? In this Chasing Starlight episode we give you an overview of some of the most popular exoplanet hunting methods.

\r\nThe instrument has 2436 fibres, which can independently move to point at the stars or galaxies researchers wish to observe. The light of these objects is then directed into spectrographs that will split it into its constituent colours, allowing astronomers to work out properties of these sources such as their composition, their speed or their distance. Over a planned 5-year survey, 4MOST is expected to capture spectra of more than 25 million different sources spread over an area larger than 60 000 full Moons.
\r\nIn this clip, the accuracy of the fibres is being tested by illuminating them from the back so that special cameras can pinpoint their exact locations and fine-tune them as necessary. The instrument, led by the Leibniz-Institut für Astrophysik Potsdam (AIP), is currently being tested and assembled at ESO’s Paranal Observatory in Chile, where it will be installed on the Visible and Infrared Survey Telescope for Astronomy (VISTA).
\r\nThis video zooms into HD 135344B, a young star located around 440 light-years away. The star is surrounded by a disc of dust and gas with prominent spiral features. New observations obtained with ESO’s Very Large Telescope (VLT) may have unveiled a planet that could be sculping these features.
\r\nThe video combines images taken with different telescopes at different times and various wavelengths. The journey begins with a wide view of the night sky in visible light. As we approach HD 135344B we see three images of the immediate vicinity of the star. First, an image of the star’s dusty disc taken with the Atacama Large Millimeter/submillimeter Array (ALMA). Then, an infrared view of the spiral arms within the disc, captured with the SPHERE instrument at the VLT. Finally, a new infrared image revealing a candidate planet, taken with the VLT’s new ERIS instrument.

Identified as a comet, 3I/ATLAS is only the third visitor from outside the Solar System ever found, after 1I/ʻOumuamua and 2I/Borisov. Its highly eccentric hyperbolic orbit, unlike that of objects in the Solar System, gave away its interstellar origin.
\r\nIn this VLT timelapse, 3I/ATLAS is seen moving to the right over the course of about 13 minutes. These data were obtained with the FORS2 instrument on the VLT on the night of 3 July 2025, just two days after the comet was first discovered. The data were made immediately public through the ESO archive.
\r\nAt the end of the video, we see all frames stacked into a single image: the deepest and best to date we have of this foreign object. But this record won’t hold for long as the comet is getting closer to Earth and becoming less faint. Currently more than 600 million kilometres away from the Sun, 3I/ATLAS is travelling towards the inner Solar System and is expected to make its closest approach to our star in late October 2025. While 3I/ATLAS will be hiding behind the Sun at that point, it will become observable again in December 2025, as it makes its way back to interstellar space.
\r\nTelescopes around the world, including the VLT, will continue to observe this rare celestial visitor for as long as they can, to find out more about its shape, its composition and its origin. What surprises will these observations reveal? Stay tuned!
\r\nCorrection (October 2025): In late October 2025, 3I/ATLAS will have its closest approach to our star, the Sun, not to the Earth as indicated in a previous version of the text. The closest approach to our planet will happen in December in 2025.
\r\nThis animation illustrates the supernova remnant SNR 0509-67.5, the leftovers of a star that died with a double-detonation. These two blasts imprinted a characteristic layered structure in the expanding material around the star. At the end of the animation we show a real image captured with ESO’s Very Large Telescope (VLT), which displays different chemical elements in different colours. The are two concentric shells of calcium, seen here in blue, a telltale sign that the star met its end with two detonations.
