The first astronomical liquid mirror telescope sees first light at the Devasthal observatory

In April 2022, the ILMT (International Liquid Mirror Telescope), located at the Devasthal Observatory in the north of India, has been used for the first time to observe the sky. This event, called the ‘first light’, marks the debut of this new telescope, designed and built by an international consortium with contributions from Belgium, Canada, India, Poland, and Uzbekistan. The [...]

Two Events in June 2022 on Asteroids, Sun and Space Exploration

In June 2022, the Royal Observatory of Belgium will participate in two events, in which it will present its activities related to asteroids, planetary defence, solar physics and space exploration. The first event will be held at the Natural Science Museum in Brussels on June 23. The second event will be held on June 24 and 25, at the Summer [...]

Belgian astronomers help create the most detailed survey of our Milky Way

13 June 2022 – Today, the European Space Agency (ESA) announces the most detailed Milky Way survey to date. The third data release of the Gaia satellite provides a wealth of information on the stars and other celestial objects that make up our Milky Way. Belgian astronomers, including scientists from the Royal Observatory of Belgium, contributed to the Europe-wide consortium [...]

‘Le Soleil et nous’, a popular book written by a scientist of the Observatory

A new book on the Sun has just been published in French, and its author, Frédéric Clette, is a researcher at the Royal Observatory of Belgium. Inspired by his career and his experience in popularising science, he presents us, in this book intended for a wide readership, a global panorama of the Sun, its multiple influences on our planet and [...]

The EUI telescope causes a revolution in solar physics

On March 26, 2022, the Solar Orbiter satellite came closer to the Sun than ever before. A particularly exciting moment. The images of this closest approach -the perihelion-, taken by the Extreme Ultraviolet Imager (EUI) on board will revolutionize solar physics! 


The largest volcanic explosion after Krakatau in 1883 studied within an international collaboration

Two Belgian researchers, including Thomas Lecocq from the Royal Observatory of Belgium, are participating in an international collaboration on the eruption of the Hunga volcano (Tonga archipelago) of 15 January 2022, the largest explosion since Krakatau in 1883. This study has just been published on Thursday 12 May 2022 in the journal Science.

On 15 January 2022, the Hunga[1] volcano (Tonga [...]

Extreme hydrometeorological events, a challenge for gravimetric and seismology networks

Measuring gravity and seismic vibrations of the ground makes it possible to observe extreme events such as the catastrophic floods that hit East Belgium in July 2021. A team of researchers led by Michel Van Camp of the Royal Observatory of Belgium has demonstrated, with gravity and seismic data from the Membach station, the importance of these measurements for understanding [...]

A patchwork image of the Sun

On 7 March, 2022, the high-resolution telescope of the Extreme Ultraviolet Imager (EUI) onboard the Solar Orbiter spacecraft made a mosaic image of the solar disk. Over a period of more than 4 hours, the satellite aimed at different positions each time capturing a small square of the Sun at very high resolution. These images were then stitched together like [...]
