Creation In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. 3 And God said, “Let there be light,” and there was light.
The sun, at 4.6 billion years old, predates all the other bodies in our solar system. But it turns out that much of the water we swim in and drink here on Earth is even older.
A new model of the chemistry of the early solar system finds that up to half the water now on Earth was inherited from an abundant supply of interstellar ice as our sun formed. That means our solar system’s moisture wasn’t the result of local conditions in the proto-planetary disk, but rather a regular feature of planetary formation — raising hopes that life could indeed exist elsewhere in the universe.
Scientists have found evidence that Earth was covered by a global ocean that turned the planet into a “water world” more than 3bn years ago.
Telltale chemical signatures were spotted in an ancient chunk of ocean crust which point to a planet once devoid of continents, the largest landmasses on Earth.
If the findings are confirmed by future work, they will help researchers to refine their theories on where and how the first single-celled life emerged on Earth, and what other worlds may be habitable.
