Земля . Обилие жидкой воды на поверхности и кислорода в атмосфере - вот, пожалуй, основные отличия Земли от всех известных на сегодняшний день небесных тел. Если земная атмосфера представляется из космоса тонкой и прозрачной, и если бы не облака, она выглядела бы совсем жалко, то занимающие около 70% поверхности океаны выглядят впечатляюще. Средняя глубина этой полноправной оболочки - гидросферы - примерно 4 км, и она представляет собой не просто заполненные водой впадины. ...

Comment on J0627-3529 . We have detected the core of an FR-I object and early-type galaxy (Venturi et al. 1995). The core is 0.54 Jy at 2.3 GHz on the Parkes-Tidbinbilla baseline (Morganti et al. 1997) and 0.6 Jy at 5 GHz (VLA data, Ekers et al. (1989) and Morganti, Killeen & Tadhunter (1993)). The VLBA image at 2.3 GHz with the resolution of 15x9 mas shows a "core-jet" structure, with the core brightness of 494 mJy/beam (Venturi et al. ...
