Scientists have recently discovered that Mars had once had a thicker atmosphere, much like Earth’s, billions of years ago. This is thanks to the detection of carbon dioxide layering in the planet’s atmosphere. This discovery is incredibly important for our understanding of the evolution of Mars’ atmosphere and climate.

In a groundbreaking new study, scientists have uncovered evidence of layering of carbon dioxide in the atmosphere of Mars. This layering is an important indicator of the past climate of the planet and suggests that billions of years ago, Mars had a much thicker atmosphere that was more similar to Earth’s. This exciting discovery could drastically change our knowledge of the evolution of Mars’ atmosphere and climate.
