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 [...]

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 [...]
