Genetic analyses of an Antarctic octopus show that the West Antarctic Ice Sheet (WAIS) collapsed during the Last Interglacial ~129,000 to 116,000 years ago when temperatures were only about 1 […]

Practicing For Ocean And Ice World Exploration: Mapping Earth’s Strongest Sea Current
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 […]
Some Icy Exoplanets May Have Habitable Oceans And Geysers
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 […]
Surface Volatile Composition as Evidence for Hydrothermal Processes Lasting Longer in Triton’s Interior Than Pluto’s
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 […]
Can Signs Of Life Be Detected On Enceladus?
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, […]
Water Content Of Rocky Exoplanets In The Habitable Zone
In this study we investigated the interiors of rocky exoplanets in order to identify those that may have large quantities of water.
Monitoring Ice World Surfaces From Orbit: Antarctic Iceberg Sails Away
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. […]
Detectability Of Local Water Reservoirs In Europa’s Surface Layer Under Consideration Of Coupled Induction
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 […]
Extended Habitability Of Exoplanets Due To Subglacial Water
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 […]
Thermal Properties Of The Leading Hemisphere Of Callisto Inferred From ALMA Observations
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 […]
