Researchers will follow up this summer with additional observations with Webb, which they hope will allow them to definitively conclude if the planet has an atmosphere. The planet whips around its star in just two days, far faster than any planet in the Solar System. “Nothing cataclysmic is happening,” he added.īased on new evidence from the NASA/ESA/CSA James Webb Space Telescope, this illustration reflects the conclusion that the exoplanet LHS 475 b is rocky and almost precisely the same size as Earth. The study’s finding, he said, “means that the inner core is now more in sync with the rest of the planet than a decade ago when it was spinning a bit faster.” “The inner core doesn’t come to a full stop,” he said. However, the speed of this rotation, and whether it varies, is debated, said Hrvoje Tkalcic, a geophysicist at the Australian National University, who was not involved in the study,

Knowing how the inner core rotates could shed light on how these layers interact and other processes deep in the Earth. The spin of the inner core is driven by the magnetic field generated in the outer core and balanced by the gravitational effects of the mantle. “When you look at the decade between 19 you see clear change but when you see 2010 to 2020 you don’t see much change,” added Song. “We show surprising observations that indicate the inner core has nearly ceased its rotation in the recent decade and may be experiencing a turning-back,” they wrote in the study. This, they said, suggested that the inner core rotation had paused. Since 2009, seismic records, which previously changed over time, showed little difference. What they found was unexpected, they said.

Martin Stollberg/TRUMPFĬar-size laser deflects lightning atop a mountain in Switzerland It was focused above a 124m high transmitter tower belonging to the operator Swisscom, equipped with a traditional lightning conductor. The 'LLR' laser has been installed on the summit of the Säntis (2500m) and was activated from June to September 2021.
