How much atmosphere is too much for life? As scientists discover more super-Earths and mini-Neptunes, the question becomes more relevant.
A decade ago, a tiny but mighty probe descended into the soupy atmosphere of Titan. This moon of Saturn is of great interest to astrobiologists because its chemistry and liquid cycle remind us of what the early Earth could ...
While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable - a balance between a sun that provides energy and a planet ...
New work from Carnegie's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.
Some people might argue that the greatest moral challenge of our time is serious enough to justify deliberately tampering with our climate to stave off the damaging effects of global warming.
The bloom that began earlier this year and shut down several shellfish fisheries along the West Coast has grown into the largest and most severe in at least a decade.
Research published today in the journal Atmospheric Environment has found that drivers are exposed to dangerously high levels of air pollutants when stopped at red lights.
NASA scientists working toward putting people on Mars said Tuesday a supersonic parachute they are developing to slow a vehicle's approach to the Red Planet partially deployed in a test, but immediately ripped apart.
In another ominous sign of human-caused climate change, US government scientists said Wednesday that global carbon dioxide concentrations have reached a new monthly record of 400 parts per million.
Venus was once considered a twin to Earth, as it's roughly the same size and is relatively close to our planet. But once astronomers looked at it seriously in the past half-century or so, a lot of contrasts emerged. The biggest ...
