Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

Craters, craters, and yet more craters: this snapshot from ESA's Mars Express is packed full of them, each as fascinating as ...

Since the 1970s, planetary geologists have known that volcanic features cover large swaths of Mars. Early Mariner 9 images ...

Researchers have identified powerful Martian electrical discharges, similar to lightning, and strong enough to be observed from orbit.

One thing that makes the Lassen Peak Trail special is its accessibility within the context of Lassen Volcanic National Park.

It measures 310,000 square kilometres (119,000 square miles) and its ‘roots’ extend around 30 kilometres (18 miles) into the Earth’s crust. (For comparison, the US state of Washington is 184,661 ...

How did young volcanoes on Mars form? This is what a recent study published in the journal Geology hopes to address as a team of scientists investigated th | Space ...

A Martian volcano once thought to be the result of a single eruption turns out to have a much more complex past. Orbital imaging and mineral data show it developed through multiple eruptive phases, ...

When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the ...

Volcanoes may look like simple mountains that erupted once and then fell silent, but in reality they are often the surface expression of complex processes happening deep underground. Magma can move, ...

Forbes contributors publish independent expert analyses and insights. Brianna Randall writes about the intersection of travel and science. The Valle de la Muerte (Death Valley) near San Pedro de ...
