Editor’s note: We have mission en route or soon to be launched to visit ice -covered ocean worlds in the Jovian system. Some day we’ll visit Enceladus and other ice-covered […]
A NASA study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential […]
Ocean worlds, or icy bodies in the outer solar system that have or once had subsurface liquid water oceans, are among the most compelling topics of astrobiology. Typically, confirming the […]
As astrophysics technology and research continue to advance, one question persists: is there life elsewhere in the universe? The Milky Way galaxy alone has hundreds of billions of celestial bodies, […]
In this study we investigated the interiors of rocky exoplanets in order to identify those that may have large quantities of water.
Editor’s note: Prime targets for Astrobiology missions in the coming decades include ice-covered ocean worlds in the outer solar system such as Europa, Enceladus, Ganymede, Callisto, Mimas, Titan and others. […]
The icy moon Europa is a primary target for the study of ocean worlds. Its subsurface ocean is expected to be subject to asymmetries on global scales (tidal deformation) and […]
Considering subglacial liquid water, a significant extension of the classical Habitable Zone is obtained. Elaborating on the model of Wandel (2023) it is shown how an atmosphere and liquid water […]
We present a thermal observation of Callisto’s leading hemisphere obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz). The angular resolution achieved for this observation was […]
It has been long puzzling whether the ice thickness variations observed on Enceladus can be sustained sorely by a polar-amplified bottom heating. The key to this question is to understand […]
