We Know More About That Underground Lake on Mars | SciShow News

The video discusses the discovery of a massive underground lake on Mars's South Pole, detected by the Mars Express spacecraft using radar technology. This finding suggests the presence of smaller water bodies, possibly formed by volcanic activity and natural salts. The video also explores the mystery of the Sun's corona being hotter than its surface, highlighting the role of nano jets and nano flares in this phenomenon. Future solar missions like NASA's Parker Solar Probe aim to provide more insights into these solar mysteries.
