29 paź 2024 · A new paper in Nature Communications makes their most compelling case to date that Mars’ life-enabling magnetic field could have survived until about 3.9 billion years ago, compared with previous estimates of 4.1 billion years — so hundreds of millions of years more recently.
1 dzień temu · Researchers at Harvard’s Paleomagnetics Lab have made a compelling case that Mars’ magnetic field, which could have supported life, lasted until 3.9 billion years ago—much later than previously thought. Evidence suggests that billions of years ago, Mars may have been a thriving environment for life. Today, however, the planet is cold, dry ...
26 lip 2024 · Yesterday, NASA announced that a rock spotted on Mars by its Perseverance rover contained some of the best signs yet that ancient microbial life may have once existed on the Red Planet.
2 lut 2022 · The late Noachian period (from 4.1 billion to 3.5 billion years ago) is the period usually thought to be habitable on Mars, with significant rain near the equator, as demonstrated by the presence of valley networks – features formed by erosion from flowing water — at this age.
5 dni temu · Currently, Mars is wobbling back and forth between 15 and 35 degrees’ obliquity, on a timescale of about 100,000 years. But every million years or so, it leans over as much as 60 degrees. Along with these changes in obliquity come changes in climate and atmosphere.
7 paź 2024 · Mars today bear signs of once having had abundant water, with features resembling valleys and deltas, and minerals that only form in the presence of liquid water. ... while cryogenic temperatures in the mid-latitudes of Mars would indicate a less habitable environment where most water is locked up in ice and not available for chemistry or ...
