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.

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

Fresh evidence of volcanic activity on Mars is reshaping how scientists think about the planet’s potential to host life, past or present. Instead of a cold, geologically dead world, Mars increasingly ...

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 the complex geological processes responsible ...
