Devastating volcanic eruptions may have been so enormous they turned the planet into “Snowball Earth” 717 million years ago, a study has found. The volcanic outburst — one of the largest in Earth’s history — likely triggered a series of chemical reactions that sucked carbon dioxide (CO2) from Earth’s ancient atmosphere. The massive eruptions, which … Read more
Planetary scientists have found groundbreaking evidence of recent volcanic activity on Venus.
