Freshwater streams and rivers naturally clean up some forms of pollution originating from urban and agricultural areas, but increased storm intensity reduces this ability.
20 years ago I made a trip to West Virginia to hang out with SETI researcher Jill Tarter and see how she searched the skies for evidence of life elsewhere….
Is there life beyond Earth in the cosmos? Astronomers looking for signs have found that our Milky Way galaxy teems with exoplanets, some with conditions that could be right for extraterrestrial life….
Stratosphere circulation is important to interpret abundances of photo-chemically produced compounds like ozone that we aim to observe to assess habitability of exoplanets….
Received via Iridium 29 November 2017 4:30:03 PM EST: “Hi Keith The earlier weather forecasts were spot on and we have had blowing snow and high winds most of the day forcing us to retreat into our various tents for…
We study the prospects for life on planets with subsurface oceans, and find that a wide range of planets can exist in diverse habitats with relatively thin ice envelopes…
Plate tectonics is a geophysical process currently unique to Earth, has an important role in regulating the Earth’s climate, and may be better understood by identifying rocky planets outside our solar system with tectonic activity….
It has been established theoretically that atmospheric thermal tides on rocky planets can lead to significant modifications of rotational evolution, both close to synchronous rotation and at faster rotations if certain resonant conditions are met….
We analyze the interiors of HD~219134~b and c, which are among the coolest super Earths detected thus far. Without using spectroscopic measurements, we aim at constraining if the possible atmospheres are hydrogen-rich or hydrogen-poor….
We report the first interstellar detection of DC7N and six 13C-bearing isotopologues of HC7N toward the dark cloud TMC-1 through observations with the Green Bank Telescope, and confirm the recent detection of HC515N….
