BioLogos

BioLogos is an Old Earth Christian site. Their ‘About Us’ page starts with the statement:

Are science and religion at war? Many people today believe they are in conflict. BioLogos exists to show that you don’t have to choose between modern science and biblical faith. Our website offers hundreds of articles, profiles, videos, and curricula, and our speakers appear at dozens of universities, churches, and conferences around the country.

Their articles tend to be short and always clearly and respectfully explained. The articles tend to integrate Christian theology within them, but the science is relevant and accessible to people of any faith.
