The surface of Venus is cracked and moves like ice floating on the ocean – likely due to tectonic activity

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.

Huge volcanic eruption didn’t cause climate change and mass extinction 140 million years ago

Huge volcanic eruptions were once believed to be the cause of mass extinctions on Earth. However, new research has found that super eruptions did not necessarily result in mass extinctions.
