This center, which inspires both historically and scientifically, promises a unique experience to its visitors by offering different activities and guided tours. How about spending time in this unique place to discover Belgium's scientific heritage?

History of the Royal Observatory of Belgium

The story of the Royal Belgian Observatory begins in 1823 with the idea of ​​the famous scientist Adolphe Quetelet to establish a scientific center. First established in Brussels, in the Saint-Josse-ten-Noode district, this observatory was equipped with the most advanced technological instruments of the time and hosted important discoveries in the world of astronomy. Today, this magnificent structure, bearing the traces of science and history, invites travelers to a journey through time.

Initially, the observatory began with studies such as calculating the longitude difference between Greenwich and Brussels, and in later years it focused on star catalogs and studies examining the movements of celestial bodies such as the Moon and Venus. This observatory, where the foundations of modern astronomy were laid, also made important contributions to fields such as meteorology and terrestrial physics in the 19th century. In particular, the first international astronomical expedition to observe the passage of Venus in front of the Sun is one of the important moments in history.

In the 20th century, the observatory underwent a major transformation. Enriched with modern instruments, the observatory pioneered developments in many fields such as astrophysics, seismology and sky mapping. In addition, the Royal Meteorological Institute, Belgium's national meteorological service, was born from this observatory.

Today, the Royal Observatory of Belgium is not only a research centre, but also a point of discovery. With telescopes used throughout history, interesting observation devices and contributions to international astronomy projects, the observatory offers its visitors a unique experience.

Institutes of the Royal Belgian Observatory

A large area on the Avenue Circulaire in Uccle is a true science center for enthusiasts of the sky and the universe! The area has evolved over the years and today brings together three different institutes: the Royal Observatory of Belgium, the Royal Meteorological Institute and the Royal Belgian Aeronautics Institute. These institutes are home to discoveries ranging from the atmosphere of the Earth and other celestial bodies to the depths of the universe.

These three prestigious institutions are housed under one roof, Pôle Espace 2. The planetarium of the Royal Belgian Observatory is also located here, offering visitors a journey through the stars. The planetarium provides an educational and fascinating experience for both adults and children.

If you want to explore a day full of science, then this is the area for you. You can learn about everything from meteorology to space aviation, astronomy to the secrets of planetary atmospheres, and explore this inspiring place where modern science and history intersect.

Science and Discovery Centre: Royal Observatory of Belgium

The Royal Observatory of Belgium is a scientific centre that seeks answers to many questions about the sky and the earth. The various research carried out under four operational departments make this observatory a special stop for science and exploration enthusiasts. Here are the areas of discovery offered by these departments:

Reference Systems and Planetology

This department focuses on navigation technologies and studies examining the physical properties of planets. Research includes the following topics:

• Space Geodesy and Time Scales: Precise positioning and timing measurements via GNSS satellites.
• The Rotation of the Earth: Measurement of the Earth's movements and axial shifts.
• Planetology: Geodetic and geophysical analyses of telluric planets (Earth-like planets) and moons.

These studies offer a dazzling depth for those who want to better understand the universe.

Seismology and Gravimetry

This department, which is the centre for research on earthquakes and gravity changes, manages seismic measurement networks throughout Belgium and Luxembourg.

• Earthquake Investigations: Monitoring and analysis of earthquakes.
• Gravity Measurements: The study of subtle changes in gravity through gravimetry.

During your visit, you can gain fascinating insight into what goes on deep underground.

Astronomy and Astrophysics

The stars and celestial bodies of the universe are the main field of study of this department. Research themes:

• Evolution and Rotation of Stars: Studies on the life cycle of stars.
• Binary and Multiple Star Systems: Study of interconnected star systems.
• Planetoid Detection: Discovery of minor planets in the solar system.
• Asteroseismology: Studies aimed at understanding the internal structure of stars.

This department offers interesting discoveries for astronomy enthusiasts.

Solar Physics and Space Weather

The observatory's internationally recognized Solar Impacts Data Analysis Center (SIDC) studies the dynamics of the Sun and space weather. Its research interests include:

• Solar Activity Monitoring: Monitoring sunspots and activity cycles with the SILSO data center.
• Space Weather Forecasts: Prediction studies that analyze the effects of the Sun on the Earth.
• Sun Viewing: Visual analyses of the Sun by spacecraft such as PROBA-2.

Solar physics and space weather studies are providing fascinating insights into the Sun, the most important star in the universe.
