The chemical reactions that dust storms on Mars cause indicate that our quest to find life on the red planet may need to go beneath the surface.

"This tells us that the basic organic chemistry needed for life is present in the raw gas prior to the formation of stars and planets."

There's growing interest in making the US food system more resilient and flexible, but soil – the origin of nearly everything we eat – is often left out of the picture.

The exoplanet Fomalhaut-b likely never was, say astronomers. Their work suggests an expanding cloud of dust instead.

The original Dust Bowl crashed US wheat production. Today, it would reduce global stocks by a third.

The star Betelgeuse dimmed 40% last year, fueling popular speculation that the red supergiant would soon explode as a massive supernova.
