Jupiter’s Europa could contain life — and these missions aim to find it

It’s brilliant news. In just over a decade, there will be two spacecraft exploring one of the most habitable worlds in the solar system – Jupiter’s moon Europa.

Scientists are taking zero-gravity flights to understand the brain’s function in space

More than 500 people have traveled into space to date and, while we know a little about how life without gravity affects our physical health, we know almost nothing about how it affects our minds.

How finding the first exoplanet changed our perception of the universe

The 2019 Nobel Prize in Physics was awarded for “contributions to our understanding of the evolution of the universe and Earth’s place in the cosmos. ” Half the prize went to cosmologist Jim Peebles, and the other half was awarded jointly to Michel Mayor and my colleague Didier Queloz for the first discovery of an exoplanet orbiting a sun-like star.
