A partial solar eclipse will take place on Saturday, 29 March 2025 and will be visible in Belgium. Instruments of the Royal Observatory of Belgium will observe it. If the weather permits it, there will also be an observation event at the Planetarium. [...]
A new documentary about the end of the dinosaur era research will be screened on March 27 and April 2, 2025, at the 2025 DOCVILLE festival in Leuven. Named ‘De dag dat het zonlicht niet meer scheen’ (The day the sun stopped shining in English), it was based on a science pitch of Cem Berk Senel from the Royal Observatory [...]
On Mars 12 2025, at 13:51 (Belgian local time), the ESA Hera mission for planetary defence made a close flyby of the planet Mars and its moons Deimos and Phobos. Scientists took the opportunity to study Deimos, photograph Mars and Phobos and calibrate Hera instruments. Scientists from Royal Observatory of Belgium (ROB) take part in the data analysis of the [...]
Recent restrictions on science and scholarship brought by the new US administration executive orders have prompted the European Federation of Academies of Sciences and Humanities (ALLEA) to respond with a statement calling for their members, partners and like-minded organisations to take a stand to safeguard academic freedom and the autonomy of scientific institutions. The Royal Observatory of Belgium (ROB) endorses [...]
Brussels, 17 February 2025 – A recent five-year study has uncovered new insights into the properties of Yellow Hypergiants, a heavy star class known for their dramatic outbursts. Scientists focused on Rho Cassiopeiae (Rho Cas), HR 8752, and HR 5171A, revealing that Rho Cas exhibits cyclical outbursts every 10 to 40 years, with large fluctuations of its surface temperature. Alex [...]
Today is the International Day of Women and Girls in Science. Let’s put those in the research fields of the Royal Observatory of Belgium in the spotlight. [...]
Previous studies posited that the mass extinction that wiped out the dinosaurs was caused by large volumes of sulfur released from rocks within the Chicxulub crater following the asteroid impact. A new paper published in the journal Nature Communications questions this scenario. The authors, including Cem Berk Senel and Özgür Karatekin of the Royal Observatory of Belgium, used groundbreaking empirical [...]
Over a period of 10 years and a half (which is 2 times the mission’s nominal duration), Gaia has provided more than a million of gigabytes of data for some 2 billion objects in the sky. At this stage, it has already had a significant impact on our knowledge of the structure, composition and dynamics of the Milky Way. [...]
In 2024, 141 earthquakes were located by the Royal Observatory of Belgium in or near Belgium.

How many earthquakes were experienced in your municipality?
In 2024, the Seismology and Gravimetry section of the Royal Observatory of Belgium (ROB) published a new paper presenting an overview of a century of felt earthquakes in Belgium. Compiling the seismic impact on Belgium was rendered possible by reviewing all testimonies of the Belgian population to the ROB on how they experienced [...]
