Cassini Finds Evidence for Hydrothermal Activity on Saturn's Moon Enceladus

Cutaway view depicting the interior of Enceladus. Water, salts, organics, and methane make their way from the hydrothermal vents on the ocean bottom to the surface through cracks in the icy crust, erupting as geysers. Image Credit: NASA/JPL

The deep oceans on Earth are teeming with life, despite the cold and darkness, thanks to […]

Scientists Debate How to Search for Life on Europa in New Mission

Jupiter’s moon Europa, with its subsurface ocean, is considered by many to be the best place in the Solar System to search for extraterrestrial life. With NASA […]

Exploring an Alien Sea: NASA Designs Submarine to Send to Titan

Who wouldn’t want to go explore an alien sea? It seems that NASA would certainly like to, and the agency has unveiled a new submarine […]

Cassini Data Indicates Enceladus' Ocean Similar to Soda Lakes on Earth

KENNEDY SPACE CENTER, FL — “A great path” lies ahead for “science and launching humans to Mars,” says astronaut […]

New Study Suggests Europa Is Far Less Geophysically Active Than Previously Thought

An artist’s impression of Jupiter and its moon Europa, based on actual visible light images. Last year, a team of astronomers using the Hubble Space Telescope, had reported the detection of signs of water vapour being vented off Europa’s south pole. A new study comes to challenge this interpretation, by presenting evidence that Europa’s […]

Coloring the Ice: Scientist Compiles First-Ever Global Color Maps of Saturn's Icy Moons From Cassini Data

A high-resolution color global map of Saturn’s moon Mimas, based on imaging data from NASA’s Cassini spacecraft. A set of new global maps of Saturn’s largest icy moons reveal the latters’ landscapes in unprecedented detail. Image Credit: NASA/JPL-Caltech/SSI/LPI

The first 50 years of planetary exploration have seen the successful completion of humanity’s epic, first […]

Dawn Spacecraft Takes Its Best-Yet Image of Dwarf Planet Ceres

The best image of dwarf planet Ceres obtained so far by the Dawn spacecraft, from 740,000 miles (1.2 million kilometers) away. Images will get much better as the spacecraft approaches Ceres over the next few months. Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

The Dawn spacecraft continues to make its way closer to a world which still hasn’t […]

ESA's JUICE Mission Receives Approval to Advance Toward Implementation
