As Next Supercontinent Forms, Arctic Ocean, Caribbean will Vanish First

Geologists at Yale University have proposed a new theory to describe the formation of supercontinents, the epic process by which Earth’s major continental blocks combine into a single vast landmass. The new model radically challenges the dominant theories of how supercontinents might take shape.

In a paper published Feb. 9 in the journal Nature, Yale researchers introduce a process called orthoversion, in which each succeeding supercontinent forms 90 degrees from the geographic center of its ancient predecessor. Under the theory, the present-day Arctic Ocean and Caribbean Sea will vanish as North and South America fuse during a mutual northward migration that leads to a collision with Europe and Asia.

Probes Suggest Magnetic Bubbles at Solar System Edge

PASADENA, Calif. –– Observations from NASA’s Voyager spacecraft, humanity’s farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.

While using a new computer model to analyze Voyager data, scientists found the sun’s distant magnetic field is made up of bubbles approximately 100 million miles (160 million kilometers) wide. The bubbles are created when magnetic field lines reorganize. The new model suggests the field lines are broken up into self-contained structures disconnected from the solar magnetic field. The findings are described in the June 9 edition of the Astrophysical Journal. (more…)
