An atmospheric haze around a faraway planet—like the one which probably shrouded and cooled the young Earth—could show that the world is potentially habitable, or even be a sign of life itself.
Stanford scientists have discovered a surprising source for an organic molecule used as an indicator for life on early Earth.
"Why would NASA want to study a lake in Canada?"
UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago—300 million years earlier than previous research suggested. The discovery indicates that life may have begun shortly ...
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.
