Most scientists believe the rate at which the moon and Earth have been bombarded by meteorites has remained constant for the past two to three billion years. Understanding the age of craters on the moon can help us better understand the age of our own planet because the Earth would have received similar numbers of impacts.

It’s been assumed that the rarity of young craters on Earth (those created 300-600 million years ago) is attributed to preservation bias — craters have been erased over the years by erosion and the movement of the Earth’s plates. Since then however, using a…

NATO’s going to call space a war zone, but don’t worry there won’t be any fighting

At an upcoming summit in early December, NATO is expected to declare space as a “warfighting domain,” partly in response to new developments in technology. If it does declare space a war zone, NATO could start using space weapons that can destroy satellites or incoming enemy missiles.

A psychotherapist explains why some adults react badly to young climate strikers

Young climate strikers I spoke to recently are confused and distressed about the things adults are doing. It’s not just inaction during the worsening climate crisis that bothers them, but the increasingly bizarre criticism many older people throw at striking schoolchildren, in the media and elsewhere.

How climate change infiltrated popular culture

It seems that people are finally waking up to the threat of climate change. The most poignant sign of this for me was seeing an infographic I created adorning the main music stage at Reading Festival 2019.

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. That’s thanks to a recent announcement by NASA that the orbiter Europa Clipper has been given the go ahead, scheduled to reach the moon at the beginning of the 2030s.

China’s emerging social credit system (SCS): rarely has a topic been more hotly discussed, and more poorly understood. When most people think about the SCS, they imagine it primarily as a scoring mechanism, a way for the central government to rank China’s citizens and companies based on their behavior.

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.
