Statistical approach improves models of atmosphere on early Earth and exoplanets
As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, ...

A spider stellar engine could move binary stars halfway across a galaxy
Eventually, every stellar civilization will have to migrate to a different star. The habitable zone around all stars changes as they age. If long-lived technological civilizations are even plausible in our universe, migration ...

Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat ...

Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for ...

Could life at TRAPPIST-1 survive the star's superflares?
The TRAPPIST-1 system is a science-fiction writer's dream. Seven Earth-sized worlds orbit a red dwarf star just 40 light-years away. Three of those worlds are within the habitable zone of the star. The system spans a distance ...
