• •A new study reveals overlooked signs of geological activity on Venus.
• •Scientists have found evidence of ongoing tectonic activity on Venus by studying giant circular features called "coronae."
• •The study suggests that Venus may be geologically active in complex and varied ways, giving researchers insight into how tectonics might work on planets without Earth-like plate boundaries.
• •Higher resolution images captured by the upcoming VERITAS mission will help clarify the results.

A recent study has uncovered evidence of ongoing geological activity on Venus, challenging previous assumptions about the planet's inactivity. Researchers examined coronae, large circular features on the surface, and found signs of subsurface forces at work. This research suggests that tectonic activity may be more widespread on Venus than previously believed. The findings offer insights into how tectonics might function on planets without Earth-like plate boundaries and potentially shed light on Earth's early history.
