Scientists uncover ozone rise in Mars' polar vortex
Riportato dall'IA
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.
ESA Mars orbiters capture images of interstellar comet
European Space Agency's Mars orbiters have observed the third known interstellar comet, 3I/ATLAS, as it passed near the Red Planet. The faint visitor, discovered in July 2025, revealed a glowing coma in images taken from about 30 million kilometers away. Researchers are analyzing the data to uncover its composition and origins.
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.
CO2 ice blocks carve mysterious gullies on Mars
Riportato dall'IA
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.
NASA Reveals Evidence of Life on Mars
Riportato dall'IA
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.
