Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.

If you put very fine black powder powder in a confined space it explodes in a cloud of heat, gas and noise.

The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.

Surface deformation or other signs of an impending explosion may not occur. Instead, supervolcanic eruptions can be much more insidious.

The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.

Asymmetric organocatalysis is an environmentally friendly way of accelerating chemical reactions and creating specific types of molecules.

Much like computing technology, the Great Red Spot has been getting smaller and faster over the last few years.

Without Benjamin List and David MacMillan, chemists would still be using metals and enzymes to catalyze chemical reactions.

A new study shows that the Bernardinelli-Bernstein Comet is much larger than previously thought — potentially the largest ever spotted.

David Julius and Ardem Patapoutian were awarded the highest honor in medicine for their research into how human bodies make sense of and respond to the outside world.

The development of the revolutionary gene-engineering tool CRISPR is a tale fit for the big screen.
