The Morning After: Scientists have confirmed a fifth layer within the Earth’s core

Destroy middle school geology posters: We have an update. A team at the Australian National University (ANU) found evidence of a new fifth layer on the planet, an iron-nickel alloy ball in the inner core. Scientists found the hidden core by studying seismic waves that travel up to five times across the Earth’s diameter – previous studies only looked at one bounce. Seismic waves probe areas near the center at angles that suggest a different crystal structure at depth.

ANU researchers also believe that the inner core is signs of a major event in Earth’s past that had a “significant” impact on the heart of the planet. As the researchers say The Washington Post, it also helps explain the formation of Earth’s magnetic field. The field plays a major role in supporting life because it protects the Earth from harmful radiation and prevents water from drifting into space.

The spacecraft landed successfully on Saturday night.


MS-23, the Soyuz spacecraft sent by Russia to bring cosmonauts Sergey Prokopyev and Dmitry Petelin and NASA astronaut Frank Rubio back to Earth, has arrived at the International Space Station. According to, the spacecraft docked with the ISS at 7:58 PM ET on Saturday night. MS-23 was scheduled to launch later this year, but Roscosmos was forced to postpone the flight after MS-22 — Prokopyev, Petelin and Rubio’s original return craft — developed a coolant leak in December following a micrometeoroid strike. If an emergency were to occur on the ISS and the entire crew had to evacuate, it is unclear whether MS-22 would be able to safely transport its crew back to Earth. That is no longer the case, now the Soyuz spacecraft has landed.
