Bacteria are the most diverse organisms on Earth, with a number of species that’s difficult to quantify. They’re also incredibly old. Bacteria consist of a single cell. They do not have bones and are ...

Stars that pass by our solar system have altered the long-term orbital evolution of planets, including Earth, and, by extension, modified our climate. "Perturbations—a minor deviation in the course of ...

In this week's Science for All newsletter, Divya Gandhi explains how water shaped Earth’s evolution three billion years ago ...

Earth's surface is the living skin of our planet—it connects the physical, chemical and biological systems. Over geological time, this surface evolves. Rivers fragment the landscape into an ...

The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...

A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For ...

Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and influencing their tectonics. New findings suggest these violent impacts ...

When the sun dies, it will become hundreds of times its current size and engulf the innermost planets. Earth may escape this infernal fate, according to state-of-the-art stellar evolution models.
