Looks like Venus is much more alive than previously thought:

 

A new study identified 37 recently active volcanic structures on Venus. The study provides some of the best evidence yet that Venus is still a geologically active planet. A research paper on the work, which was conducted by researchers at the University of Maryland and the Institute of Geophysics at ETH Zurich, Switzerland, was published in the journal Nature Geoscience on July 20, 2020.

I've always suspected the coronae looked a little bit like volcanic collapse calderas on Earth, but without the giant ash flow sheets, which would be suppressed by Venus' thick atmosphere.  Curiously, though, there seems to be a somewhat similar remnant on Mars, on the southeast side of which is perched Olympus Mons.  I wonder if that could be the collapsed roof of a magma chamber, after the magma itself had been injected out to one side, producing the giant volcano.

 

We desperately need higher resolution images, and a lander that can withstand the heat long enough to do a little soil sampling.
