Mars "asleep". Extraordinary discovery on the Red Planet

A study published in Science Advances reveals that hydrochloric acid detected in Mars' atmosphere may indicate volcanic activity beneath the surface. Researchers suggest that the presence of this gas, particularly around Alba Mons, points to emissions from potentially dormant volcanoes. Observations show an annual increase in hydrochloric acid concentration during early summer, possibly linked to underground magma processes. This discovery raises questions about Mars' geological activity and its implications for the potential existence of life, as volcanic activity could create warmer environments that support microbial life.
