What if the Massive Martian Lakes Weren’t Lakes At All?

Scientists from the University of Hong Kong (HKU) have presented new research that challenges the popular Gale crater hypothesis on Mars. Until now, data from the Curiosity rover indicated that this crater in ancient times could have been a deep lake. However, an alternative view of the same data showed that the crater may have never been a Martian lake.

60,000-Year-Old Cave Art in Spain was Made by Neanderthals

Scientists have discovered in the Spanish cave of Ardales drawings left by Neanderthals between 45 and 65 thousand years ago. Chemical analysis showed that the cave art in Spain was of man-made origin, and archaic people brought ocher from outside the monument. Apparently, karst formations played a symbolic role among some groups of Neanderthals.
