A new study led by The Australian National University (ANU) has found seawater cycles throughout the Earth’s interior down to 2,900 km (1,800 miles), much deeper than previously thought, reopening questions about how the atmosphere and oceans formed….
By Ned Rozell As another major rainstorm hit California in February, downtown San Francisco surpassed its normal rain total for an entire year. Reservoirs in the high country were spilling over. So ended a five-year drought in the state that some people attributed to human-caused climate change. Those pictures of dried-up California lakes bothered Syun-Ichi Akasofu, who recently gave a talk “The Forthcoming Ice Age” at the University of Alaska …
Origin date/time: Fri, 24 Feb 17 08:48:08 GMT; Location: CULGAITH,CUMBRIA ; Lat/long: 54.669,-2.594; Depth: 7km; Magnitude: 0.5
Rocky planets orbiting M-dwarf stars in the habitable zone tend to be driven to synchronous rotation by tidal dissipation, potentially causing difficulties for maintaining a habitable climate on the planet….
There exists a positive correlation between orbital eccentricity and the average stellar flux that planets receive from their parent star. Often, though, it is assumed that the average equilibrium temperature would correspondingly increase with eccentricity….

With the discovery of rocky planets in the temperate habitable zone (HZ) of the close-by cool star TRAPPIST-1 the question of whether such planets could also harbour life arises….
Origin date/time: Wed, 22 Feb 17 21:20:23 GMT; Location: KAMES,ARGYLL AND BUTE ; Lat/long: 55.904,-5.278; Depth: 18km; Magnitude: 0.4
NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is…
