Strange signals on Venus may be coming from an erupting volcano
Now, using archival observations from old orbiter missions and the results of experimental work conducted on Earth, a team of scientists is making the case that the 1.5-mile high, 125-mile wide Idunn Mons has been active within the past few thousand years, and is likely still erupting today. They won’t have to wait long to confirm their hunch: Within the next decade, a small squadron of missions capable of detecting volcanic activity on the surface will begin their journeys to Venus.
