They say variety is the spice of life, and now new discoveries from Johns Hopkins researchers suggest that a certain elemental ‘variety’—sulfur—is indeed a ‘spice’ that can perhaps point to signs of life.

NASA's Wide Field Infrared Survey Telescope (WFIRST) will identify planets with large orbits, similar to our solar system's far-flung giants, Uranus and Neptune.

The Mars Helicopter is riding to the Red Planet this summer with NASA's Perseverance rover. The helicopter's chief engineer, Bob Balaram, shares the saga of how it came into being.

Cornell astronomers have created five models representing key points from our planet’s evolution, like chemical snapshots through Earth’s own geologic epochs.

A recent study is contributing to our understanding of the end-Cretaceous mass extinction, which occurred some 66 million years ago. This event is possibly best known for wiping out the dinosaurs, and is one of the most well-studied mass extinctions in Earth’s history.

Along with capturing an image before its steepest ascent ever, the Curiosity Mars Rover robotic explorer filmed its "selfie stick," or robotic arm, in action.

using ESO’s Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals.

To help answer one of the great existential questions - how did life begin? - a new study combines biological and cosmological models. It reveals life in the universe could be common, but not in our neighborhood

By measuring iron isotopes, researchers from the University of Copenhagen have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.

Research team explores how fundamental features of genome affects organism's ability to thrive in an extreme environment on Earth and beyond.
