Five Ways We Study Baby Planets

Some say there is nothing that beats the joy of watching a child grow up. But what about watching a planet grow up?

Most Of Earth’s Carbon Was Hidden In The Core During Its Formative Years

Comparing carbon's compatibility with the silicates that comprise the Earth’s mantle (outer circle) to its compatibility with the iron that comprises the planet’s core (inner circle)

New work published this week in Proceedings of the National Academy of Sciences reveals how carbon behaved during Earth’s violent formative period. The findings can help scientists understand how much carbon likely exists in the planet’s core and the contributions it could make to the chemical and dynamic activity occurring there—including to the convective motion powering the magnetic field that protects Earth from cosmic radiation.

A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska’s Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes. The findings are published in Scientific Reports by Helen Janiszewski, recently of Carnegie, now at the University of Hawaiʻi at Mānoa, and Carnegie’s Lara Wagner and Diana Roman.

Hélène Le Mével prepares for a year-long study in Chile to study Villarrica volcano, one of the most active volcanoes in the world. The study will include one of the most-extensive monitoring plans to date for the volcano, which is a popular tourist destination. It will also present an opportunity to pioneer the use of gravity as a monitoring tool.
