A peculiar bright burst of radio waves in the Milky Way

What's out there? It's a fundamental but fascinating question in space science. Back in 1969, we managed to first travel to our neighbour, the Moon, and explore it. However, the whole picture is much more complex as most objects in the Universe are too far... click to read more

A missing ingredient in dark matter theories?

In 1933, Fritz Zwicky, observing the Coma galaxy cluster, noted that single galaxies were moving too fast for the cluster to remain bound, according to the measure of visible mass. Only a far more significant amount of invisible matter could explain the strong gravitational force... click to read more
