Researchers at the Caltech have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past.
Scientists have found a way to take the temperature of dinosaurs that have been extinct for millions of years.
Finds that rocks used as key geologic evidence were formed deep within Earth millions of years after the ice age ended.
Researchers use a ground-breaking technique that reveals a relationship between cooler temperatures and Earth's second largest mass extinction, which occurred about 450 million years ago.
Although you won't find oceans, lakes, or even a shallow puddle on the moon's surface, a team of geologists has found structurally bound hydroxyl groups (water) in a mineral in a lunar rock returned to Earth by the Apollo program.
Geochemical findings could help explain facets of early human evolution, including the development of bipedalism.
Could help scientists track paleoclimate, determine whether dinosaurs and other species were warm- or cold-blooded.
