... Credit Copyright: Elisabetta Bonora Marco Faccin ( Alive Universe Images ) Explanation: Spacecraft Rosetta continues to approach, circle, and map Comet Churyumov-Gerasimenko. Crossing the inner Solar System for ten years to reach the vicinity of the comet last month, the robotic spacecraft continues to image the unusual double-lobed comet nucleus . The reconstructed-color image featured, taken about 10 days ago, indicates how dark this comet nucleus is. ... NASA Official: Jay Norris. ...

... Существующие на Европе (спутнике Юпитера) кратеры от столкновения с космическими объектами говорят о том, что толщина его ледяного покрова, скрывающего жидкий океан, составляет более 3-4 км, с таким заявлением выступили ученые Аризонского университета. ... Один из самых известных кратеров Европы, 24-километровый Pwyll, является обладателем центрального возвышения диаметром 5 км и высотой 500 м. Если бы под пиком Pwyll'а находился теплый лед, то он разрушился бы менее, чем через год. ...
... Interacting galaxies . ... Catalogues . ... We define a volume limited sample of over 14,000 early-type galaxies (ETGs) selected from data release six of the Sloan Digital Sky Survey. The density of environment of each galaxy is robustly measured. By comparing narrow band spectral line indices with recent models of simple stellar populations (SSPs) we investigate trends in the star formation history as a function of galaxy mass (velocity dispersion), density of environment and galactic radius. ...
