1. SGL X Star Party Timelapse


    from James Mackay Added

    I've combined three (and a bit) timelapses taken from the Stargazers Lounge's astronomy forum (www.stargazerslounge.com) annual star party at Lucksall Camping & Caravan Site near Hereford, held this year 19th - 23rd March 2015. All three nights I attended had clear patches but with a considerable amount of high cloud which is visible in the video. Most of the footage was captured using a Canon 6D with 14mm Samyang lens video, the last few seconds were captured on a modified Canon 650D although approaching daylight didn't allow for the modded nature of the camera to show. All exposures were 30 seconds, mostly at either f/2.8 or f/3.2.

                This video sequence starts with a broad view of the Milky Way before closing in on the sky close to the familiar bright star Sirius. The final sequence shows a new VLT image of the Thor’s Helmet Nebula taken on the occasion of ESO’s 50th Anniversary, 5 October 2012, with the help of Brigitte Bailleul — winner of the Tweet Your Way to the VLT! competition.

                    Earliest atmospheres of terrestrial planets: Steam atmospheres, carbon atmospheres, and ocean planets Linda T. Elkins-Tanton, Massachusetts Institute of Technology Terrestrial planets may obtain atmospheres from three primary sources: Capture of nebular gases, degassing during accretion, and degassing from subsequent tectonic activity. Though the first atmospheres on the Earth and Mars have been changed and lost past recognition, they may have played important roles in determining the future of the planets’ surfaces and their habitability. Compositions of primitive and differentiated meteorites provide a range of reasonable starting bulk materials for planetary formation and atmospheric degassing. These compositions may have been processed through a planetary melting event (a magma ocean), assumed to occur one or more times during accretion of planets in the first tens of millions of years of planetary formation through highenergy impacts of large bodies. These physical processes produce predictions for the mass and composition of degassed atmospheres as well as for the initial composition and density of the planetary silicate mantle, from which comes later degassing into the atmosphere. A very small initial water content (less than a half mass percent) in the accreting Earth can produce a dense steam atmosphere, while a small change in chemistry can produce a carbon-based atmosphere, such as that on Venus. The presence of surface water may be critical in both preventing a Venusian runaway greenhouse and encouraging plate tectonics. Further, modest initial water contents (10 mass% of the planet and above) create planets with deep surface liquid water oceans soon after accretion is complete.
