Gravitational waves are ripples in spacetime. The phenomenon can be compared to ripples on a sheet when a heavy ball is placed on it and spun around. In the universe, these "balls" are massive objects such as black holes and neutron stars, which vibrate spacetime as they orbit and eventually merge. These gravitational waves are emitted through space and, although very subtle, can be detected on Earth with the correct equipment.

A team of researchers led by Vincent Pelgrims (ULB) dust off the Galaxy to build the first 3D map of the Universe's magnetic field. A new launch for astronomy, allowing us to explore the depths of the sky like never before. A study published in the journal Astronomy & Astrophysics. The space between stars is "dirty".

From April 15 to 19, Benoit Scheid and his team produced and observed, for the very first time in the world, antibubbles in zero gravity. Their work could lead to advances in water treatment and drug encapsulation . Twice a year, the European Space Agency (ESA) organizes weightlessness (or microgravity) flights.

Researchers from the Department of Chemical Engineering at the Vrije Universiteit Brussel, Riga Technical University and the MESA+ Institute at the University of Twente have succeeded in arranging very small particles (10 µm to 500 nm, 10 to 100 times thinner than a human hair) in a thin layer without using solvents.
