A potential volcanic eruption on Mars
One thing that Earth and Mars apparently share is volcanic activity. We know that volcanoes exist on Earth and have seen how much damage they can cause when they erupt. This is far more significant than if it happened on Mars, where there would apparently be no life forms affected by it. However, this doesn’t mean that volcanic eruptions here don’t do anything remarkable. The next of these unusual images of Mars reveals what may well be a 50,000-year-old (or less) volcanic eruption site. According to one research team, the “mysterious dark deposit” in this photo – which is apparently slightly larger than Washington D.C. – could be a volcanic deposit.
Water drops on Mars?
The fact that there could be water on Mars doesn’t mean that the planet experiences rain as it does on Earth. In fact, it seems an incredibly long time since Mars experienced such a phenomenon, which could explain why it’s so dry and dusty here. Of course, while there may be no rain, that doesn’t mean there are no raindrops. It seems that NASA has already captured an image of some of the dunes around the Copernicus crater, and it’s hard not to see them as raindrops. Curiously, their existence is actually linked to the lack of rain. That’s because they’re rich in olivine, a mineral that isn’t found much on the Earth’s surface because it quickly turns to clay when exposed to water.
