‘Born-again’ star offers rare chance to watch stellar evolution in real time

Le Binh San Pham — Wed, 16 Sep 2026 09:49:34 +0000

A team of astronomers led by the Royal Observatory of Belgium have found that a star called Sakurai’s Object has become 6 times hotter in the past 30 years, one of the fastest increases ever seen. Sakurai’s Object is a dead star which re-ignited in the 1990’s as a ‘born-again’ star. 30 years ago it was similar in temperature to our Sun. It has now entered a new stage of stellar evolution, representing a Wolf-Rayet star. New observations show the star is reheating more gradually than some of the most recent theories predicted, providing an important test of theories describing the final stages of a star’s life. The rapidly changing star offers astronomers a rare opportunity to watch stellar evolution unfold in real time.

Using the European Southern Observatory’s Very Large Telescope (VLT) in Chile, researchers, led by Peter van Hoof and Griet Van de Steene from the Royal Observatory of Belgium, studied Sakurai’s Object, a rare ‘born-again’ star that unexpectedly burst back to life in 1996 after reaching the final stages of its evolution.

Their findings, published today in Monthly Notices of the Royal Astronomical Society, show that the star has entered a new phase of its evolution, developing the powerful stellar wind characteristic of Wolf-Rayet stars.

The research provides new insight into the final stages of stellar evolution and helps astronomers test theories that would otherwise take thousands or millions of years to verify.

As a result of the evolution of Sakurai’s Object, it has also been increasing in luminosity a lot between 2006 and 2023. In this video Sakurai’s Object is marked by the green circle. Credits: Peter van Hoof (ROB).

Dr Peter van Hoof of the Observatory said: “For most stars it is impossible to see them evolve on a human timescale. To understand their evolution, our only choice is to observe many different stars and piece together which of those are on different stages of the same path. Sakurai’s Object offers something far rarer. It is one of the very few stars known to have changed dramatically within just a few decades, giving us the opportunity to watch stellar evolution unfold in real time. With our observations, we can test theories of how stars evolve and gain new insights into one of the shortest and least understood phases in the life of a dying star.”

The scientists believe the star was similar to our Sun, but had already ended nuclear burning and begun its journey towards becoming a white dwarf – the hot, dense core left behind after an ordinary star dies. It underwent a rare event known as a “very late thermal pulse”, when a layer of helium deep inside the dead star suddenly reignites.

The event caused the star to rapidly expand, cool and eject large amounts of material into space, temporarily returning to an earlier stage of its life, leading astronomers to describe it as a “born-again” star.

Only two stars have ever been directly observed undergoing this type of dramatic rebirth: Sakurai’s Object and V605 Aquilae.

Following its outburst, Sakurai’s Object became hidden behind thick clouds of gas and dust released during the eruption, making it difficult to study directly.

To investigate its current state, the team analysed light collected by the Very Large Telescope and compared it with sophisticated computer models that simulate the atmospheres and powerful winds of Wolf-Rayet stars.

The observations revealed distinctive signatures of carbon and helium, allowing the researchers to find its temperature, chemical composition and the characteristics of its stellar wind.

Their analysis suggests the star’s surface temperature is currently between around 27,000 and 36,000 degrees Kelvin, showing that it is reheating following its dramatic eruption nearly three decades ago.

Dr Griet Van de Steene of the Observatory added: “Sakurai’s Object evolved much more quickly than pre-existing models for stellar evolution predicted. This led to a new generation of models that we now need to test. Our measurements show that the star is reheating more gradually than some of these new models predicted. That gives us an important way of testing which theories best describe what happens when a dying star briefly springs back to life. As we continue to monitor the star over the coming years, we expect to learn much more about this remarkable phase of stellar evolution.”

The findings also suggest that Sakurai’s Object is at an earlier stage of its evolution than V605 Aquilae, which experienced a similar event around 80 years ago.

The team will continue observing Sakurai’s Object as it continues reheating and resumes its journey towards becoming a white dwarf, learning more about one of the most rapid and unusual phases of stellar evolution ever observed.

The findings have been published in Monthly Notices of the Royal Astronomical Society

ERC Starting Grant Awarded to a Researcher at the Royal Observatory

Le Binh San Pham — Thu, 03 Sep 2026 10:02:35 +0000

The European Research Council (ERC) today announced the winners of its latest Starting Grant competition. Kaustubh Hakim, researcher at both the Royal Observatory of Belgium and KU Leuven, has been awarded a grant for the ExoGeochem project, with the Observatory as host institution.

The ERC Starting Grants are awarded to early-career researchers across Europe. The grants will help researchers develop ambitious ideas, build their own teams and establish their independence at a pivotal stage in their careers.

Kaustubh Hakim is one of the 421 laureates of the ERC Starting Grant. The scientist holds a joint appointment between the Royal Observatory of Belgium and the Institute of Astronomy at KU Leuven through the BELSPO FED-tWIN programme. He is the first active researcher in the FED-tWIN programme to be awarded an ERC grant.

He trained first as an electronics engineer and worked in banking before turning to astronomy, for a master’s degree in Belgium, a PhD in the Netherlands and a long postdoctoral position in Switzerland before returning to Belgium. His research connects geochemistry and planetary science to work out what exoplanets are made of.

A grant for studying exoplanets through modelling, high-pressure experiments and observations

The project ExoGeochem (Geochemical Atmospheric Signatures of Sub-Neptune Exoplanets) is hosted by the Royal Observatory of Belgium, with KU Leuven as a beneficiary partner. It aims to establish what sub-Neptune exoplanets are made of, and how their interiors shape the atmospheres we observe.

Roughly half of the exoplanets found so far belong to this class: worlds between twice the size of Earth and the size of Neptune. Our own solar system contains nothing like them, which leaves astronomers without a reference point for what lies beneath their thick atmospheres.

ExoGeochem will supply the thermochemical data that are missing: how hydrogen, rock and iron behave when they meet at the pressures and temperatures found deep inside such planets. Laboratory experiments, quantum-mechanical simulations and atmospheric chemistry models will be brought together into a single framework, so that spectra recorded by the James Webb Space Telescope, and later by Ariel and the Extremely Large Telescope, can be read in terms of what a planet is actually made of.

The Starting Grant will provide about €1.5 million over a maximum period of five years. As the Principal Investigator, Kaustubh Hakim will recruit and supervise the team and take scientific responsibility for executing the project. Part of the budget will equip a laboratory with diamond anvil cells, in which sub-millimetre-sized samples are squeezed and heated to reproduce conditions deep inside a planet. His own scientific contribution centres on the interior–atmosphere interactions in rocky and sub-Neptune exoplanets, which is the thread tying the theoretical, experimental and observational parts of the project together.

“Planetary interiors have been studied at the Royal Observatory for decades, but mostly through models,” says Hakim. “What this grant makes possible is to recreate those conditions in the laboratory, measure what actually happens, and then take those numbers back to the telescope data. Closing that loop between experiment and observation is what has been missing for sub-Neptunes.”

Solar eclipse of August 2026 in Humain

Le Binh San Pham — Fri, 21 Aug 2026 10:04:20 +0000

On 12 August 2026, a total solar eclipse took place. While people had the chance to witness the totality of this event in Spain, Iceland and Greenland, eclipse watchers from Belgium witness the Moon covering about 90% of the Sun. On this occasion, the Royal Observatory of Belgium organised an eclipse observation event in its radioastronomy station in Humain (Marche-en-Famenne) and welcomed about 300 visitors.

In Humain, the eclipse began at 19:20, with a maximum at 20:14 and ended at 21:07, a few minutes after sunset (at 20:58). The site offers a clear view of the setting Sun, which allowed people to enjoy the eclipse from the beginning to nearly its end with eclipse glasses.

Solar telescopes were also installed for visitors to observe the eclipse in more detail, and, on the surface of a white tent, they could view the eclipse with alternative ways (by projecting sunlight through a skimmer for example).

The sunlight is projected on the white tent through a skimmer and holes of a cardboard. Through the holes, one can observe the eclipsed Sun. Credit: ORB-KSB.

Beside eclipse viewing, visitors also had the occasion to learn more about solar physics and space weather research at the Observatory, discover how a seismometer works and visit a new museum about the history of the Humain radioastronomy station. After sunset, the remaining people had the occasion to see Venus with the naked eye. The event ended at 22:30, with a few lucky observers admiring the first Perseid shooting stars of the night.

In Uccle and in space

In Uccle, the solar telescopes, with their advantage of being placed 12 m above the ground, had the chance to take snapshots of the eclipse. The space-based solar telescopes managed by the Observatory were also at the ready. The Proba-2 travels so fast around Earth that it crossed the Moon’s shadow multiple times allowing its instruments, SWAP and LYRA, to capture three partial eclipses in a row. The ASPIICS instrument onboard Proba-3 observed at the same time a natural total solar eclipse by the Moon and an artificial eclipse by its occulting satellite covering the solar disk. This is double eclipse will only happen once during the mission’s lifetime.

Solar eclipses take place two to three times a year, some of which are total solar eclipses. However, each of these events is only visible from a small region on Earth and the zone where the totality can be observed is even smaller.

Fortunately, the next total solar eclipse that will be partially visible in Belgium is not far away: it will take place next year, on 2 August 2027, with the totality visible in North-Africa and the south of Spain. In Belgium, the Moon will cover a bit less than half of the surface of the Sun. Precise times of the solar and lunar eclipses in Belgium in 2027 will soon be published on the Information website of the Observatory.

Stay tuned and don’t put your eclipse glasses too far away!

The Observatory Publishes Its Podcasts

Le Binh San Pham — Fri, 14 Aug 2026 18:18:06 +0000

Since June 2026, the Royal Observatory of Belgium has been publishing a series of podcasts entitled Sous les coupoles d’Uccle/Onder de koepels van Ukkel (Under the domes of Uccle in English). The podcasts are freely available on Spotify, Apple Podcasts, YouTube Studio or via an RSS feed.

Every month, the Observatory’s scientists take you to the heart of their research, from space missions to the most distant stars, via the measurement of time. Episodes are released alternately in French and Dutch. For listeners who do not understand Dutch (or French), a summary of the podcast is available in the notes for the Dutch language (or French language) episode.

Two episodes are already available. The first episode, Le bruit de la Terre (The Noise of the Earth in English), is in French and, featuring Raphael De Plaen, explores seismic noise as a tool for understanding the climate, the subsurface and natural hazards. The second episode, in Dutch, is entitled Belgische blik op de Zon (A Belgian Glance at the Sun in English) and, with David Berghmans and Elke D’Huys, talks about the role of the Royal Observatory in space missions, higlighting the SOHO, Proba-2, Solar Orbiter and Proba-3 missions.

Sous les coupoles d’Uccle/Onder the koepels van Ukkel is one of the special publications and activities marking the 200^thanniversary of the Royal Observatory of Belgium. The first series will comprise 12 episodes.

Music, Sound & Imagination Exhibition at the Royal Palace

Flore Van Maldeghem — Wed, 08 Jul 2026 07:43:03 +0000

From July 3 to August 16, 2026, the Royal Palace is open to the public. This is an opportunity to explore the “Science and Culture” exhibition entitled Music, Sound & Imagination.

In the Grand Gallery, visitors can discover objects, works of art, sound clips and documents, all relating to sound and music. The Music, Sound & Imagination exhibition is organised by Belspo in collaboration with the Federal Scientific Institutes, of which the Royal Observatory of Belgium is a member, as well as the Royal Conservatoire of Brussels and the Queen Elisabeth Music Chapel.

Star Sounds and a Mini-Podcast

On this occasion, the Royal Observatory of Belgium has collaborated with the AstroSounds project to present “star sounds” to the public. AstroSounds is a citizen science project inviting members of the public to analyse the light spectra of stars that have been converted into sounds. Stars vibrate, and by studying their vibrations, we can glean information about the interiors of these celestial bodies. This science, known as asteroseismology, is one of the Observatory’s fields of expertise.

Just like the sounds of musical instruments, the “sounds” of stars are distinguished by their timbre, making it possible to recognise the type of star simply by listening to them. The exhibition and the Observatory’s website showcase the sounds of four types of stars: a sun-like star, an RR Lyrae star, a Beta Cephei star and a classical Cepheid.

Visitors will also have the opportunity to discover other sounds linked to the Observatory and its activities. The mini-podcast, which is also available online, invites listeners to experience a day in the heart of the Observatory’s laboratories and to discover the daily lives of its scientists.

Successful Proba-3 mission extended until 2028

Le Binh San Pham — Tue, 16 Jun 2026 13:42:39 +0000

The European Space Agency’s (ESA) Proba-3 mission is extended until August 2028. This space mission, involving a significant Belgian contribution, is studying the lower layers of the Sun’s corona. The pair of satellites were originally due to complete their mission at the end of this year. Thanks to the exceptional scientific and technological results already achieved by this space mission, it was decided to allow the two satellites to continue their work until 31 August 2028 in order to carry out more extensive research.

The lifespan of satellite missions can vary greatly, from a few years to decades. This depends mainly on their objective, but also on the orbit in which they are situated, and how precisely they are placed into orbit by the launcher. Normally, an initial duration is planned for each mission, which can then be extended if the ESA member states wish to do so, there is a budget for it and the satellite is still in good condition. An extension thus provides additional scientific value and maximises the return on investment.

This is also the case for Proba-3. This mission was launched on 5 December 2024 with the aim of creating artificial solar eclipses using two satellites. This allows them to study the solar corona, which is otherwise only briefly visible during natural solar eclipses.

‘Since the start of operations, the satellite constellation has already delivered a large amount of high-quality data,’ says Ronald Van der Linden, Director of the Royal Observatory of Belgium. ‘The unique formation is working exceptionally well. This allows us to study the lower layers of the solar corona in great detail, something that was previously impossible. Now that the satellites will be operational for longer, we can continue these important studies. Among other things, this helps us to better understand the Sun’s activity and to predict solar storms and streams of fast solar wind. In this way, we can better protect terrestrial technologies, our space infrastructure and astronauts from the dangerous consequences of these phenomena.’

Belgium’s key role

Belgium plays a central role in this space mission, with a contribution of approximately 66 million euros out of a total budget of 166 million euros, funded via the Belgian Science Policy Office (BELSPO) through Belgium’s contribution to ESA. The chairman of BELSPO, Arnaud Vajda, is pleased: ‘The two satellites have proven their robustness. Earlier this year, we briefly lost contact, but this was restored and operations were able to resume in full. The extension of the mission demonstrates that this feat of technology is worth continuing to develop. It confirms the success of this ambitious mission and Belgium’s strong position within European space activities.’

The extension is funded through ESA’s science programme, a mandatory programme run by the agency, and therefore does not require any new investment from our country.

The Royal Observatory of Belgium leads the scientific operation of the coronagraph, which is the mission’s core task. Other instruments have also been installed on the satellites, such as 3DEES, in which the Royal Belgian Institute for Space Aeronomy is involved. This instrument measures high-energy particles around the Earth to better understand radiation in space. Thanks to this knowledge, we can better protect space infrastructure such as satellites, but also astronauts, especially if they were to travel to the Moon or eventually to Mars.

200 candles for the Royal Observatory of Belgium

Le Binh San Pham — Mon, 08 Jun 2026 16:04:33 +0000

8 June 2026 marks the 200^th anniversary of the Royal Observatory of Belgium. To mark the occasion, the institute organises a wide range of activities, with events scheduled right through to 2027. These are regularly updated on the Observatory’s 200^th anniversary website: 200year.observatory.be.

An institute that has grown throughout 200 years

The Observatory was founded before the creation of the Belgian state, on the initiative of the mathematician, statistician and astronomer Adolphe Quetelet. Wishing to establish an observatory in a territory corresponding to present-day Belgium, he submitted a report to King William I of the Netherlands. The latter, having accepted Quetelet’s proposal, signed the decree establishing the Observatory on 8 June 1826.

Decree of the foundation of the Royal Observatory of Belgium stored in the archives of the Brussels City and exhibited during the special event of 5 June 2026 in the occasion of the 200^th of the Royal Observatory of Belgium. The full transcription of the decree can be found here. Credit: ORB-KSB.

Over the past 200 years, the institute has embraced scientific revolutions and expanded its expertise in Earth and space sciences. It also moved from Saint-Josse-ten-Noode to its current site in Uccle. Two other related institutes emerged from the Observatory: the Royal Meteorological Institute and the Royal Belgian Institute for Space Aeronomy, both also located on the Uccle plateau.

Today, the Royal Observatory of Belgium has established itself on the international stage for its scientific expertise, particularly in astronomy, timekeeping, solar physics, seismology, gravimetry, geodesy using GNSS positioning satellites, planetary science and space weather.

To mark this anniversary, the Royal Observatory of Belgium organised a special event for distinguished guests, presenting them the planned activities as well as an exhibition of its antique books. It also invited the entire staff from the institutes on the Uccle site and their external sites to a social event featuring a barbecue and various games.

A range of activities until 2027

For the public, the Observatory, together with its Planetarium located at the Heysel site, plans a wide range of activities and publications to mark this jubilee year, including

Open door days on the weekend of 26 and 27 September 2026, together with the Royal Meteorological Institute and the Royal Institute for Space Aeronomy of Belgium;
Guided tours of the solar physics and space weather departement,
Guided tours of the Humain site (located near Rochefort),
An observation evening of the solar eclipse and the Perseid meteor shower in Humain on 12 August 2026,
Street astronomy sessions,
Concerts at the Planetarium in January 2027, with the Brussels Philharmonic,
Lectures at the Palace of the Academies in French and Dutch, in collaboration with the Collège Belgique of the Académie royale de Belgique for the French-speaking part.

Also worth noting are lectures at the Planetarium, evening visits and observations through the large 45 cm telescope, the publication of a book to mark the Observatory’s 200^th anniversary, the release of podcasts, an exhibition at the Planetarium, an exhibition on the grids of the Uccle plateau, the issue of special stamps in collaboration with bpost, and the release of a special coin in collaboration with the National Geographic Institute and the National Bank of Belgium.

The calendar of events is regularly updated on the Observatory’s 200^thanniversary website, where you will also find anecdotes for every day of the year as well as walking routes in Brussels and in Belgium on the theme of astronomy.

Airborne validation of new-generation satellites for weather and climate

Le Binh San Pham — Mon, 01 Jun 2026 09:49:15 +0000

From the 1^st to the 30^th of June 2026 an airborne campaign – with the name MAGIC Avalon – will take place over France and Belgium for the validation of the new European weather satellite Metop-Second Generation.

The Royal Observatory of Belgium participates in this campaign in collaboration with the Laboratoire d’Optique Atmosphérique (LOA) of the University of Lille. They are specifically focused on demonstrating the capabilities of the future climate mission Earth Climate Observatory (ECO).

ECO is currently at the end of its Phase 0 study as a candidate of the ESA Earth Explorer 12 future space mission, aimed at measuring the most essential of all climate variables: the Earth Energy Imbalance. The Phase 0 will be concluded by an EE12 User Consultation Meeting held in Tallinn, Estonia on 7-8 July 2026, where it will be decided whether ECO can continue to Phase A studies.

A key concept of the ECO space mission is the combination of cameras for high resolution observation, and a radiometer for high accuracy observation. This concept will be tested in the MAGIC Avalon campaign from the combination of the OSIRIS camera with a baffled CMP22 pyranometer. A test flight took place on the 9^th of April in the South of France, the data of this test flight is currently analysed and shows promising results, that will be presented at the EE12 UCM.
