The presence of electrical activity has implications for surface chemistry, future human exploration and habitability on the Red Planet

A minor earthquake struck California in the early hours of the morning on November 26

Launched just a little over three months ago, Copernicus Sentinel-5A has returned its first images – including a global map of ozone, maps of nitrogen dioxide over the Middle East and South Africa, formaldehyde over parts of Africa, and emissions of sulphur dioxide from an active volcano in Russia – showcasing the mission’s powerful capability to monitor atmospheric gases worldwide.

The first high-resolution images have been received from Copernicus Sentinel-1D and were shared publicly for the first time at the European Space Agency’s Ministerial Council, held today in Bremen, Germany. Glaciers in Antarctica, the tip of South America, as well as the city of Bremen, are visible in these stunning radar images.

What are the physics of life? That is more than just a philosophical question - it has practical implications for our search for life elsewhere in the galaxy. We know what Earth life looks like, on a number of levels, but finding it on another planet could require us to redefine what we even mean by life itself. A new paper from Stuart Bartlett of Cal Tech and his co-authors provides a new framework for how life could be defined that could reach beyond just what we understand from our one Pale Blue Dot.

Wild turkeys once nearly disappeared, but today they’re thriving.
