A routine survey of the U.S. Atlantic Coastline recently revealed a strange phenomenon. Multitudes of gas plumes were seen bubbling up to the ocean surface, and though the gas has yet to be analyzed, scientists are almost certain that it is methane.

"We don’t know of any explanation that fits as well as methane," said lead study author Adam Skarke, a geologist at Mississippi State University in Mississippi State.

With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.

The work shows, Valley says, that the time when our planet was a fiery ball covered in a magma ocean came earlier.
