Are there any active volcanos on the Moon?
The Moon’s volcanoes have been extinct for billions of years. The dark spots you see on the Moon are ancient lava flows and most of these were deposited between 3 and 4 billion years ago! The youngest mare rock is thought to be approximiately 1 billion years old, but as no direct samples have been made of these rocks, that age is not very well constrained. So I’m sorry to report that “no, there are no active volcanoes on the Moon.”
