Super-earth or mini-Neptune? Telling habitable worlds apart from lifeless gas giants
Perhaps the most intriguing exoplanets found so far are those bigger than our rocky, oceanic Earth but smaller than cold, gas-shrouded Uranus and Neptune. This mysterious class of in-between planets—alternatively ...
Cassini probe gets close views of large Saturn hurricane (w/ video)
(Phys.org) —NASA's Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole.
Scientists detect water around a hot Jupiter
Scientists at the Naval Research Laboratory (NRL) are part of a research team that has detected water vapor in the atmosphere of a planet outside our solar system. The team, including scientists from California ...
Novel membrane reveals water molecules will bounce off a liquid surface
Consider the nearest water surface: a half-full glass on your desk, a puddle outside your window, or a lake across town. All of these surfaces represent liquid-vapor interfaces, where liquid meets air. Molecules of water ...
Planners for hypersonic SpaceLiner craft propose a 50 year timeline
A hot new look at working fuel cells
Measuring a fuel cell's overall performance is relatively easy, but measuring its components individually as they work together is a challenge. That's because one of the best experimental techniques for investigating ...
Study estimates rate of intensification of extreme tropical rainfall with global warming
Extreme precipitation in the tropics comes in many forms: thunderstorm complexes, flood-inducing monsoons and wide-sweeping cyclones like the recent Hurricane Isaac.
Panasonic trims Ene-Farm fuel cell size and price
Nature can selectively buffer human-caused global warming
Can naturally occurring processes selectively buffer the full brunt of global warming caused by greenhouse gas emissions resulting from human activities?
Water in stratosphere plays key role in Earth's climate
Water vapor changes in the stratosphere contribute to warmer temperatures and likely play an important role in the evolution of Earth's climate, says a research team led by a Texas A&M University professor.
Chemists' discovery could be breakthrough in developing new tools for cleaner air and energy production
(Phys.org) —Chemists at the University of South Florida and King Abdullah University of Science and Technology have discovered a more efficient, less expensive and reusable material for carbon dioxide (CO2) capture an ...
Rugged, rapid monitor safeguards space crews
There are few things as important on, and especially off, Earth as breathable, quality air. When air quality is compromised, we often don't have seconds to spare, which is why development of the Multi-Gas ...
UCLA study yields more accurate data on thousands of years of climate change
Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world.
