In its early life, Earth suffered a meteorite pummelling that lasted 100 million years and may have changed its chemical makeup forever, researchers said Wednesday.
Anyone who's ever noticed a water puddle drying in the sun has seen an environment that may have driven the type of chemical reactions that scientists believe were critical to the formation of life on the early Earth.
Early Earth was an inhospitable place where the planet was often bombarded by comets and other large astrophysical bodies.
A new view of the Moon's formation: Crucial difference in 'fingerprints' confirms explosive, interconnected past
Within the first 150 million years after our solar system formed, a giant body roughly the size of Mars struck and merged with Earth, blasting a huge cloud of rock and debris into space. This cloud would eventually coalesce ...
One of the most important areas in all of biology is the evolution of photosynthesis. Some species of single celled cyanobacteria, through photosynthesis, forever changed the atmosphere of the early Earth by filling it with ...
Our young sun may have routinely blasted Earth with gobs of energy more powerful than any similar bombardments recorded in human history.
A spark from a lightning bolt, interstellar dust, or a subsea volcano could have triggered the very first life on Earth. But what happened next? Life can exist without oxygen, but without plentiful nitrogen to build genes ...
How do you take the temperature of the Earth billions of years ago? The answer lies in the rocks.
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates.
The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
