Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
A team of scientists from the Lunar and Planetary Laboratory at the University of Arizona, TU Delft, and Caltech has developed a new method to compute...
Europa and Enceladus are key targets to search for evidence of alien life in our Solar System. However, the surface and shallow subsurface of these airless...
Ocean worlds are planetary bodies that have a liquid ocean, often under an icy shell or within the rocky interior. In our own Solar System, several moons...
Enceladus, the sixth-biggest moon of Saturn, presents a remarkable opportunity in our Solar System for searching for evidence of extraterrestrial life,...
Using data from NASA’s Cassini mission, planetary scientists have detected several compounds of strong importance to the habitability of Saturn’s icy...
Astronomers from NASA and the University of Washington have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets...
Enceladus is a prime target in the search for life in the Solar System, identified by NASA as the second-highest priority site for a flagship mission in...
This new image of Saturn, taken with the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope on June 25, 2023, serves as...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
As Enceladus orbits rapidly around Saturn with a period of only 1.37 Earth days, the ejected water vapor is spread along and around its orbit, forming...
The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets because of...
Enceladus, the sixth-biggest moon of Saturn, is a top candidate in the search for extraterrestrial life in the Solar System.
An artist’s impression of...
Enceladus is one of the prime targets in the search for life in our Solar System. Observations made by NASA’s Cassini spacecraft show that this small...
The underwater snow is known to form in low temperature environments, e.g., beneath ice shelves, on Earth. New research led by University of Texas at Austin...
Someday, dozens of tiny swimming robots could whisk through the water beneath the icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking...
Saturn’s 500-km- (300-mile) diameter moon Enceladus is covered in ice which contains many long fractures or rifts, including fractures called tiger stripes....
Observations from NASA’s Cassini spacecraft established that Enceladus, the sixth-largest of Saturn’s moons, has a global subsurface ocean. An analysis...
A novel theory proposed by planetary scientists from Caltech and NASA’s Jet Propulsion Laboratory challenges the current thinking that the saltwater...
