Today's Picture of the Week depicts different angles of a very peculiar asteroid named (44) Nysa. Asteroids are leftovers from the formation of planets in the Solar System, with the majority found in a circular belt between Mars and Jupiter. These rocky bodies come in various shapes and sizes, but new images of (44) Nysa, located at the inner edge of the asteroid belt, reveal an unusual structure unlike anything observed before!
\r\nTo resolve (44) Nysa’s shape, a team of astronomers used the SPHERE instrument on ESO’s Very Large Telescope in Chile, and SHARK-VIS, an instrument by the Italian National Institute for Astrophysics on the Large Binocular Telescope in the USA. Both instruments use adaptive optics to correct atmospheric blur and obtain crisp images of this asteroid.
\r\nThe data shows that the asteroid is 80 km across and is composed of three distinct blobs, or ‘lobes’, joined by two narrower sections that encircle the asteroid, or ‘necks’. All previous identifications of asteroids with a neck have been interpreted as ‘bilobates’, having just two lobes, but (44) Nysa has a unique ‘trilobate’ structure.
\r\nThe team has two possible explanations for how (44) Nysa got its odd shape. Either the asteroid originates from a single object that was heavily deformed though collisions, or is a composite of three objects that impacted and merged, forming necks at the point of contact.
\r\nFurther research is needed to clarify which hypothesis holds true, but for now astronomers are delighted to have determined the structure of (44) Nysa, which had long evaded attempts to identify its true nature. The asteroid is named after the mythical birthplace of the ancient Greek god Dionysus, who is associated with theatre and masks. “The name is quite fitting, after the land of a god known for concealing his true nature,” says Kate Minker, lead author of the study announcing the discovery. “We’ve managed to finally unmask (44) Nysa”.
\r\nThis video takes us to the red supergiant star Betelgeuse, where astronomers have obtained the clearest image yet of what likely is a companion star orbiting it: Betelgeuse B.
\r\nThe video combines images taken at different times with various telescopes at different wavelengths. It begins with a wide view of the sky in visible light. At 0:22 we see a mid-infrared image taken with the VISIR instrument at ESO’s Very Large Telescope (VLT), showing a large and complex dusty envelope around Betelgeuse.
\r\nAs we keep zooming in we eventually see Betelgeuse’s surface at 0:35, imaged in January 2019 with the SPHERE instrument, also at the VLT. The video ends with another SPHERE image where Betelgeuse has been removed, revealing a bright source next to it which is likely its companion, Betelgeuse B. This image was obtained in December 2024, when the companion was predicted to be furthest away from Betelgeuse as seen from Earth.

\r\nThis animation demonstrates how astronomers found a ‘moon’ in the CD-35 2722 system. CD-35 2722 is a star about half as massive as the Sun, seen here in the background (point-like source). It has a companion: a brown dwarf that orbits the star approximately every 5000 years. This brown dwarf is 37 times more massive than Jupiter: too massive to be a planet, but not massive enough to be a star.
\r\nThe brown dwarf is, in turn, orbited by another object. The gravitational pull of this ‘moon’ makes the brown dwarf wobble back and forth. This periodically shifts the spectrum of the brown dwarf towards bluer and redder colours via the Doppler effect.
\r\nAstronomers used the CRIRES+ spectrograph at ESO’s Very Large Telescope (VLT) to monitor the brown dwarf over a couple of years. They found evidence of an object at least as massive as Jupiter orbiting the brown dwarf every 170 days. Interestingly, this ‘moon’ is as massive as a planet, and it orbits an object that is neither a planet nor a star.

The telescope’s construction saw a lot of progress and important milestones during this time. The entire project is more than 75% complete and closer than ever to helping us understand more of the secrets of our Universe.
\r\nThe ELT’s dome, still partially uncovered and showing its steel skeleton in the beginning of this video, has mostly finished receiving its layer of protective insulated cladding, designed to protect the telescope and its instruments from the harsh desert environment, including very rare but heavy rains. When the massive doors were installed the dome reached its highest point of 80 meters in April of 2025, with a topping-out ceremony that featured the raising of ESO and Chile flags on top of the dome. Later in the year, the dome’s doors were moved for the first time.
\r\nMeanwhile, inside the dome, the main structure of the ELT, that will hold its mirrors and instruments, is progressing fast. This structure, currently weighing around 3500 tonnes, was recently rotated around its vertical axis for the first time.
\r\nThis video doesn’t capture the advances carried out off-site, such as testing the ELT’s deformable mirror, key to correct atmospheric turbulence and obtain sharp images. The construction of MICADO and METIS, the first instruments to be installed at the ELT, is also progressing well. An agreement for MOSAIC, another ELT instrument, was signed in the end of 2025. With the telescope components and instruments coming together, the ELT is well on its way to start observing the cosmos later this decade.
\r\nThis video compiles footage and time-lapses of ESO’s Extremely Large Telescope (ELT), taken between January 2025 and July 2026. The video shows progress in the construction of the dome and the telescope’s main structure. For more information about the advances made in this period, check this page.

ESO staff at the construction site, together with Ace/Cimolai’s team, who are leading the construction of the dome and main structure, rotated the telescope first by hand by a few centimetres, and then a full rotation using auxiliary motors. While this may seem small, the entire structure currently weighs around 3500 tonnes, which will further increase up to 4600 tonnes once the mirrors and science instruments are installed. The structure rests on a layer of oil just 80 microns thin that allows the telescope to rotate smoothly. Testing this motion is thus key to ensure that this massive telescope can point at all areas of the southern sky.
\r\nThis time-lapse shows satellites crossing the night sky above the northern Atacama Desert in Chile, over a period of just one hour. The video was taken on 15 October 2025, about two hours after sunset. A few streaks are caused by planes, and can be easily identified by their blinking-coloured lights, but most trails are due to satellites.
\r\nIn the foreground we see the dome of ESO’s Extremely Large Telescope (ELT), the world’s largest optical/infrared telescope, currently under construction atop Cerro Armazones. Behind it we see the lasers of ESO’s Very Large Telescope (VLT) at Paranal Observatory, 22 km away from the ELT.

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.

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.

This detailed image consists of 554 million pixels, and is a combined mosaic image of observations taken with the 268-million-pixel OmegaCAM camera at the VLT Survey Telescope, hosted at ESO’s Paranal Observatory.
\r\nOmegaCAM can take images through several filters that each let the telescope see the light emitted in a distinct colour. To capture this image, four filters have been used, represented here by a combination of magenta, blue, green and red. The result is an extremely detailed and stunning view of both the gaseous filaments in the remnant and the foreground bright blue stars that add sparkle to the image.

\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\nToday’s Picture of the Week, taken with ESO’s Very Large Telescope (VLT), is in fact a series of images taken over the course of four years, showing a rotating disc of gas and dust around the young star AB Aurigae. 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\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!

It will detect high energy radiation from some of the most powerful events in the Universe, from supernova explosions to hungry black holes. But our atmosphere protects us from gamma rays, so how will the CTAO achieve this? By doing something seemingly impossible: observing particles that move faster than light, without breaking the laws of physics.

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.
