Could more of Earth’s surface host life?

Of all known planets, Earth is as friendly to life as any planet could possibly be — or is it? If Jupiter’s orbit changes, a new study shows Earth could be more hospitable than it is today. When a planet has a perfectly circular orbit around its star, the distance...

Sleeping giant could end deep ocean life 

A previously overlooked factor — the position of continents — helps fill Earth’s oceans with life-supporting oxygen. Continental movement could ultimately have the opposite effect, killing most deep ocean creatures. “Continental drift seems so slow, like nothing drastic could come from it, but when the ocean is primed, even a...
