“Earth may have had more than enough ingredients to form water from the beginning,” said planetary scientist Patrick Shober, who was not involved in the research.

Water is fundamental to life on Earth, yet the origins of this vital resource remain a scientific puzzle. Researchers have long debated whether comets, asteroids, or both were the main ...

The origin of life on Earth stands as one of the great mysteries of science. To find out if we are alone in the galaxy, we will need to better understand what geochemical conditions nurtured the first ...

Meteorites - rocks that fall to Earth from space - have pelted our planet from its birth about 4.5 billion years ago to today, often causing scant damage but sometimes triggering cataclysms.

Researchers say they discovered evidence that early Earth was home to more hydrogen than previously thought, calling into question widely held beliefs about the origins of water and the planet’s ...
