For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research ...

In an investigation to find out what sparked life on Earth, researchers have discovered that RNA formed through surprisingly ...

Evidence is mounting that the same basic chemistry that made Earth habitable is unfolding, or once unfolded, on Mars. From ...

Grab-and-go missions to asteroids have provided some of the most scientifically valuable samples since the Apollo ...

The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of ...

Polyester microdroplets, possible precursors to life, were formed from alpha-hydroxy acids (αHAs) in early Earth-like conditions even at low reaction volume, low reactant concentrations, and/or high ...

A new study suggests that cloud-to-ground lightning might have been key in creating the building blocks essential for life on Earth from nitrogen and carbon. In Earth's early days, comets, asteroids ...

A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years ...

Earth was not always the blue-green world we know today: the early Earth's oxygen levels were about a million times lower than we now experience. There were no forests and no animals. For ancient ...

Scientists have uncovered a surprising role for calcium in shaping the building blocks of life. Their study reveals that calcium ions help determine the molecular 'handedness' (chirality) of tartaric ...

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in surprising and fascinating ways.
