Supernovas May Have Triggered Two Mass Extinctions on Earth
A new study suggests that two of Earth's biggest mass extinction events might have been caused by nearby supernovas, based on calculations of supernova rates from the past billion years and their potential impact on Earth's ozone layer.

Earth's Inner Core Deforms, Potentially Affecting Magnetic Field
New research reveals that the Earth's inner core has deformed by approximately 100 meters or more in places over the past two decades, potentially impacting the planet's magnetic field; scientists used seismic wave data from 1991-2023 to make this discovery.

Ancient Meteorite Suggests Earth Was Inherently Hydrated
Analysis of a 4.6-billion-year-old enstatite chondrite meteorite reveals intrinsic hydrogen, suggesting Earth was inherently hydrated, challenging the theory that water arrived via asteroid impacts.

Supernovae Linked to Two Mass Extinction Events
A study suggests that two of Earth's five mass extinction events may have been caused by nearby supernovae, occurring roughly every 400 million years, based on an analysis of OB stars and the timing of ozone depletion events.

Earth's Inner Core Shape Changes Detected
Scientists have discovered evidence of changes in the shape of Earth's inner core over the past 20 years, using data from seismic waves generated by earthquakes; this builds upon the 2024 discovery that the inner core recently reversed its spin and now rotates backward relative to the rest of the pl...
