Scientists uncover ozone rise in Mars' polar vortex
Researchers have observed a dramatic buildup of ozone inside Mars' north polar vortex, where extreme cold and darkness freeze out water vapor. This phenomenon, detected using data from ESA and NASA orbiters, offers insights into the planet's ancient atmospheric chemistry and potential habitability. The findings were presented at a joint meeting in Helsinki.
Martian permafrost may hide veins of habitable liquid water
New calculations suggest that Mars's frozen subsurface could contain networks of narrow liquid water channels large enough to support microbial life. These veins, formed in permafrost, might exist in regions with high salt content that prevents freezing. Researchers argue this could be a promising site for searching extraterrestrial life.
Martian volcanoes may have delivered ice to equator
Scientists propose that explosive volcanic eruptions billions of years ago transported water from Mars's interior to its equatorial regions, forming thick ice layers beneath the surface. This mechanism explains radar-detected ice in the planet's hottest area without relying on shifts in Mars's axial tilt. The discovery could aid future human missions by providing accessible water resources.
NASA Reveals Evidence of Life on Mars
Von KI berichtet
NASA scientists have uncovered the strongest evidence yet of potential life on Mars through analysis of recent rover data. The findings include organic compounds that suggest microbial activity in the planet's past. This discovery was announced in a press conference today.
CO2 ice blocks carve mysterious gullies on Mars
Scientists have uncovered how blocks of frozen carbon dioxide dig eerie channels into Martian dunes through explosive sublimation. Lab experiments replicating Martian conditions revealed the process, matching observed features on the Red Planet. The discovery explains a long-standing geological puzzle without needing water or life.
