velvetclassic.netIs Mars Really Red? A Physicist Explains the Science Behind Its Colour and More
A physicist explains the science behind Mars’s red appearance, linking its hue to iron oxide or rust. While known as the Red Planet, rover images and telescope data show varied colors, from tan to white ice caps. Observations in ultraviolet and infrared light reveal deeper insights into Mars’s atmosphere, surface, and seasonal changes, enriching planetary science.
A recent study published in Science Advances suggests that the enigma of water loss on Mars could be directly linked to solar radiation, a hypothesis that marks a radical shift in the understanding of Martian climate.For decades, scientists have suspected that Mars was once a watery world, full of rivers, lakes and even oceans.The traces of this humid past are still visible in its eroded geography and meandering valleys.The new research, led by …
Out-of-season water escape during Mars’ northern summer triggered by a strong localized dust storm
Mars almost certainly had a significant amount of water in its past. Recent observations reveal that during southern summer, when the atmosphere is warmer and dustier, water vapor can reach high altitudes without condensing, leading to water loss to space. Here, we identify a new pathway for wate...
