I wouldn't rule out volcanic just yet. We've never seen any volcanic interaction with the incredibly thick Venus atmosphere. So we cannot be sure how that would transpire. There could be some totally unexpected consequences for such an event. And if this is purely atmospheric in nature, then why haven't we seen something of this magnitude before?
I'm not ruling out anything at this point, including comet or large asteroid hit. But a comet hit is unlikely because we should have seen it long before it struck. If it blindsided the planet, then that would be equally unusual and unlikely. In some respects this event might be more interesting if it is purely atmospheric in nature. We need more data. Does anybody have an idea where that might come from at this point? |
