Jul 28, 2023 · We don’t know for sure, though, and looking for evidence of past life on Venus is almost impossible with current technologies. Although orbiters can teach us a lot about a planet, to search for signs of past life we need to take a much closer look. On Mars, we look for past microbial life by sending rovers like Curiosity and Perseverance to ...
Nov 6, 2023 · Tectonic Clues Point to a Habitable Past. A recent study has turned the tables on our understanding of Venus by suggesting it once featured Earth-like plate tectonics. This assertion, derived from Venus’s current atmospheric composition, signals that the planet might have supported life billions of years ago. Credit: NASA/JPL.
Mar 28, 2024 · Alien life could thrive in Venus' acidic clouds, new study hints. Earth life may have traveled to Venus aboard sky-skimming asteroid. "It doesn't mean that life there will be the same as here. In ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
The ultimate goal of NASA’s exoplanet program is to find unmistakable signs of current life on a planet beyond Earth. How soon that can happen depends on two unknowns: the prevalence of life in the galaxy and how lucky we get as we take those first, tentative, exploratory steps. Our early planet finding missions, such […]
Sep 29, 2023 · Many are optimistic of detecting life signs on a faraway world within our lifetimes - possibly in the next few years. And one scientist, leading a mission to Jupiter, goes as far as saying it ...

Nov 10, 2020 · Venus is a kind of negative to Earth’s positive; by studying what went so very wrong, we might learn what it takes to get life right. “Venus gives us an example of an alternative evolution for planets,” said Vikki Meadows, an astrobiologist who heads the Virtual Planetary Laboratory in NASA’s Nexus for Exoplanet System Science.
