New analyses suggest that the four largest moons of Uranus may hold a reservoir of liquid water beneath their thick crusts, possibly filled with ammonium salts. The heat preserved within these icy moons\u2019 interiors is thought to be enough to melt up to 30 km of the salt and ammonia-rich water ice. Under this sub-glacial ocean, there may even be conditions that are capable of supporting life. Previously, the icy moons of the outer Solar System were considered to be cold, frozen worlds, but now it is understood that several of them have liquid water and possibly life-sustaining conditions beneath their surfaces, including Jupiter\u2019s Europa, Ganymede and Callisto, Saturn\u2019s Enceladus and Titan, and even the distant dwarf planet Pluto and its moon Charon. Julie Castillo-Rogez of NASA\u2019s Jet Propulsion Laboratory said that \u201cplanetary scientists have found evidence of oceans in the most unlikely places, like the dwarf planet Ceres and Pluto and Saturn\u2019s moon Mimas. So there are mechanisms at play here that we don\u2019t yet fully understand.\u201d The four largest Uranus moons – Ariel, Umbriel, Titania and Oberon \u2013 are now thought to be some of the newest candidates for sub-glacial oceans, holding enough heat to prevent their complete cooling. The analysis suggests that the moons\u2019 crusts may be thick and porous enough to isolate the warmer interior, and the presence of ammonia and other salts would allow the water to remain liquid even at lower temperatures.<\/p>\n

Forscher haben neue Erkenntnisse \u00fcber die Monde des Planeten Uranus gewonnen. Es besteht die M\u00f6glichkeit, dass sich unter der dicken Kruste der vier gr\u00f6\u00dften Uranusmonde ein Reservoir aus fl\u00fcssigem Wasser mit Ammoniumsalzen befindet. Die innere Hitze dieser eisigen Monde k\u00f6nnte ausreichen, um bis zu 30 km aus Salz und Ammoniak-reichem Wassereis zu schmelzen. In diesen subglazialen Ozeanen k\u00f6nnten sogar Lebensbedingungen vorherrschen.\u00a0<\/p>\n
